Waves can transfer energy from one place to another. There are two main types of waves: longitudinal waves, which vibrate the medium in the direction of travel, and transverse waves, which vibrate at right angles to the direction of travel. The key parts of a wave include the crest (high point), through (low point), wavelength (distance between corresponding points), and amplitude (maximum vibration distance from rest position).

There are two main types of progressive waves: transverse waves and longitudinal waves. Transverse waves involve particle motion perpendicular to the direction of wave propagation, with crests and troughs. Longitudinal waves involve particle motion parallel to propagation, characterized by regions of compression and rarefaction where particles are close together or spread apart.WAVES

There are two main ways that waves can be classified: by what they move through (the medium) and by how the energy moves through the medium. Waves that require a medium are mechanical waves like sound, water, and seismic waves. Electromagnetic waves can travel through matter or empty space. Mechanical waves are further divided into compressional/longitudinal waves where the medium vibrates parallel to the wave direction, and transverse waves where the medium vibrates perpendicular to the wave direction. Examples of each type of wave and their characteristics are provided.Wave Properties

Waves carry energy through matter or space in different forms. There are two main types of waves - mechanical waves which require a medium and electromagnetic waves which do not. Mechanical waves include waves on strings, springs, water surfaces and sound waves. Electromagnetic waves include visible light, infrared, radio waves, x-rays and gamma rays. A medium is the material that mechanical waves travel through such as solids, liquids, gases or combinations. Waves can be periodic, meaning the medium particles oscillate repeatedly.Physics: Waves

Here are the solutions to the seatwork problems:
1. Amplitude = 32 cm = 0.32 m
Period = 1/2.4 Hz = 0.416 s
Wavelength = 48 cm = 0.48 m
2. Speed = 6200 miles / 15 hours = 411 mph = 183 m/s
3. Wavelength = Speed / Frequency
= 2.997 x 108 m/s / 1.023 x 108 Hz
= 2.93 m
4. Speed = Distance / Time = 50 m / 21.8 s = 2.29 m/s

Reflection occurs when a wave bounces off a surface it cannot pass through and does not change the wave's speed or frequency but may flip it upside down. Refraction is the bending of a wave as it enters a new medium and occurs because the wave speed changes, with one side moving slower. Diffraction causes a wave to bend around obstacles, with larger wavelengths diffracting more. Interference results from waves combining constructively to make a larger displacement or destructively to make a smaller one. A standing wave appears stationary and has nodes of no displacement and antinodes halfway between nodes.Two types of_waves

Waves transfer energy and are made up of pulses. There are two main types of waves: transverse waves, where particle movement is perpendicular to velocity, and longitudinal waves, where particle movement is parallel to velocity. Longitudinal waves have two parts - compressions where particles are closer together, and rarefactions where they are farther apart. When two waves meet, their amplitudes add through interference and superposition, which can make the combined wave bigger or smaller.Waves Basics

Waves are caused by wind dragging across the surface of water, causing the water to oscillate rather than move as a solid block. Individual water particles move in circles while the wave energy travels forward. Key characteristics of waves include their height from trough to crest, wavelength between two crests, and period of time for one full wavelength to pass. Wave size depends on wind speed, duration, and the distance of open water over which the wind blows known as fetch. As waves approach shore, their speed decreases causing their height to increase and wavelength to decrease, sometimes causing waves to break.Wave motion

Okay, let's break this down step-by-step:
* Mr. H vibrates the snakey 32 times in 10 seconds
* So the frequency is 32/10 = 3.2 Hz
* There are 4 sections each occupied by an antinode
* Since there are nodes between each antinode, there must be 5 nodes total
* With 5 nodes, this is the 5th harmonic standing wave pattern
* The 5th harmonic has 6 nodes
* So the wavelength is the total length (6.2 m) divided by 6 nodes
* Wavelength = 6.2 m / 6 = 1.033 m
* Using the wave equation: Speed = Frequency x Wavelength
* Speed = 3Wsl Power Point

Chemistry is the study of matter, its properties, and its reactions. It examines how substances combine or change through various reactions and interactions. Chemistry can be considered a physical science as it studies matter and its transformations but does not examine living things. Some major branches of chemistry include organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry, and biochemistry. Chemistry plays an important role in daily life through applications in food, medicine, cleaning products, and more.Introduction to matter
Introduction to matterAndres Orozco
油
Matter is everything that has mass and takes up space. It is made up of tiny particles called atoms, which can combine to form molecules or compounds. There are three main states of matter: solid, liquid, and gas. Matter undergoes physical or chemical changes that alter its properties but not its chemical makeup.Solids, liquids and gases
Solids, liquids and gasesAndres Orozco
油
This document defines the three states of matter - solids, liquids, and gases. It explains that solids have particles that barely move and hold a defined shape, liquids have particles that flow freely but maintain a constant volume, and gases have particles that have no defined volume or shape and move very quickly. The document also notes that all states of matter are made up of particles that move at different speeds depending on whether they are a solid, liquid, or gas.Motion
MotionAndres Orozco
油
Motion refers to the change in an object's position or location over time. Kinematics is the study of motion without regard to forces or energies. An object is considered in motion if its position changes relative to a reference point.
Velocity refers to both an object's speed and direction of motion. Speed in a given direction is called velocity. Average speed is calculated by dividing the total distance traveled by the total time taken. Instantaneous speed refers to an object's speed at a given instant in time.
Acceleration is a vector quantity that represents the rate of change of velocity. It occurs when an object changes its speed. The formula for calculating acceleration is the change in final velocity minus initial velocity divided by the change in timeEnegry samuel

Energy is the ability to do work or cause change and there are different types, the most important being kinetic and potential energy. Kinetic energy is related to motion and calculated using the formula of half mass times velocity squared, while potential energy is energy that can be released to transform into kinetic energy, as stated by Newton's law of conservation of energy. This law says that energy is neither created nor destroyed, merely changed from one form to another, which is important for understanding how devices like solar panels and batteries work by transforming energy. Other types include chemical (stored in food), thermal (related to heat), and nuclear (from atomic nuclei fusion or fission).Introduction to Chemical Bonds
Introduction to Chemical BondsAndres Orozco
油
Atoms form ions by gaining or losing electrons to achieve a full outer electron shell like noble gases. Ions then bond to form ionic compounds between metals and nonmetals like NaCl. Covalent bonds form when atoms share electrons to achieve full outer shells, like in H2O. Polyatomic ions, which are ions of two or more bonded atoms, can also participate in ionic bonding, such as Ca(OH)2 which contains hydroxide ions bonding to calcium ions. The number of each type of atom in a compound is shown by subscripts based on the ions formed.Chapter1

Chemistry is the science that studies the composition, structure, and properties of matter. It plays an important role in our daily lives through the materials we use and consume like fuels for cars, medicines, and food. Ancient civilizations had a basic understanding of chemistry through extracting metals, making alloys and ceramics, and using fermentation. The field of chemistry began to take shape in the 17th century with Robert Boyle's work developing the scientific method and questioning existing theories through experimentation.Elements pererz e i単aky

Elements are composed of atoms of the same class that can be found naturally or created artificially in a laboratory. There are four main types of elements: alkali metals, halogens, transition metals, and noble gases. Noble gases are the most stable elements with full outer electron shells, while halogens have seven outer electrons and alkali metals have one. Transition metals occupy the central portion of the periodic table. Elements are classified based on their atomic numbers and valence electrons.Redox reactions
Redox reactionsAndres Orozco
油
Redox reactions involve the transfer of electrons between atoms or molecules. During redox, oxidation and reduction occur simultaneously. Oxidation is the loss of electrons by an atom, increasing its oxidation state, while reduction is the gain of electrons by an atom, decreasing its oxidation state. Metals typically undergo oxidation by losing electrons, while nonmetals gain electrons through reduction. The oxidation states of elements in compounds can be determined based on established rules and used to balance redox reactions.Bonds

This document defines and explains key chemistry concepts such as chemical bonds, molecules, substances, pure and not pure substances, compounds, covalent and ionic bonds, polyatomic ions, protons, electrons, valence electrons, and the periodic table. It discusses how chemical bonds form between atoms through the sharing or transfer of electrons. It also describes the differences between pure substances like elements and compounds, and not pure or heterogeneous substances. Key aspects of the periodic table such as its organization, atomic number, electron configuration and use in predicting chemical reactivity are outlined.Naming and writing compounds
Naming and writing compoundsAndres Orozco
油
This document provides instructions for writing formulas and naming different types of compounds. It explains that to write formulas, you must identify the elements and ions using the periodic table and write the cation first followed by the anion, balancing charges using the crisscross method. The three main types of compounds are ionic without transition metals, ionic with transition metals specified by Roman numerals, and covalent using prefixes and suffixes. Polyatomic ions also have set names and follow normal compound naming rules.Elements [chemistry]1

The document defines several key terms related to atoms and their structure. It explains that atoms are the fundamental building blocks of matter, consisting of protons, neutrons, and electrons. The nucleus of an atom contains protons and neutrons, while electrons orbit the nucleus in shells or orbitals. Valence electrons are located in the outermost orbital. The periodic table arranges the elements and groups them according to their chemical properties and number of valence electrons. Ions are atoms that have gained or lost electrons, giving them a positive or negative charge. Electronegativity refers to an atom's ability to attract electrons towards itself.Biochemistry
Biochemistry Andres Orozco

Biochemistry is the study of chemical processes within and relating to living organisms. There are four main classes of biomolecules: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates, lipids, proteins, and nucleic acids all have distinct structures and functions within the body. Carbohydrates provide energy and support various systems, proteins have a variety of roles including structure and defense, and lipids store energy and are components of cell membranes.Biochemistry

Biochemistry is the study of chemical processes within and relating to living organisms. There are four main classes of biomolecules: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates, lipids, proteins, and nucleic acids all have different structures and functions within the body. Carbohydrates provide energy and support various systems, proteins have a variety of roles including structure and defense, and lipids store energy and are composed of hydrocarbon chains.Diego a

John Steinbeck Popular Short Story
The Pearl adalah sebuah novella yang ditulis oleh John Steinbeck yang mengisahkan perjuangan seorang nelayan miskin bernama Kino dan istrinya, Juana, yang hidup sederhana di sebuah desa kecil Meksiko. Suatu hari, Kino menemukan sebuah mutiara raksasa "the Pearl of the World" yang diyakini akan mengubah nasib mereka.
Namun, alih-alih membawa kebahagiaan, mutiara itu justru menimbulkan keserakahan, kekerasan, dan penderitaan. Masyarakat di sekitarnya mulai menunjukkan niat jahat, dan bahkan keluarga Kino sendiri terjebak dalam konflik batin antara harapan dan kehancuran. Pada akhirnya, The Pearl menjadi simbol ironi: sesuatu yang tampak sebagai berkah berubah menjadi kutukan.
Melalui cerita ini, Steinbeck mengeksplorasi tema keserakahan, harapan, kemiskinan, dan ketimpangan sosial. Dengan gaya narasi yang lugas namun penuh makna simbolik, The Pearl menjadi refleksi tajam tentang sifat manusia dan dampak tragis dari keinginan yang tak terkendali.

In an era where users are bombarded with endless choices, capturing attention and driving meaningful engagement isn't just about building features it's about understanding what drives human behavior at its core. This presentation offers a deep dive into how psychological principles can inform smarter, more intuitive product decisions. Its not just theory its a hands-on blueprint for applying human-centered thinking at every stage of product development.
Grounded in behavioral science, consumer psychology, and cognitive design, this deck unpacks the key psychological drivers behind user motivation, decision-making, emotional engagement, and habit formation. From attention economics and dopamine-driven interactions to trust cues, loss aversion, and the paradox of choice you'll see how to harness what the mind naturally does to build digital products people dont just use they return to, talk about, and even advocate for.
Well explore:
Cognitive biases that shape user perception and choices and how to use them to your advantage without crossing ethical lines.
Emotional design principles that build trust, trigger desire, and turn features into feelings.
User behavior loops that build stickiness, deepen retention, and create emotional investments.
Psychological friction when to reduce it for conversion, and when to add it for intentionality.
Dark patterns vs. ethical persuasion the thin line between influence and manipulation.
A/B testing with a psychological lens learning not just what works, but why it works.
This is more than UX research or product marketing fluff. Its a call to build with empathy, backed by science, and sharpened by real-world product thinking. Whether youre shaping onboarding flows, gamifying engagement, designing pricing models, or rethinking retention strategies this deck will arm you with a new lens: the human mind.
Perfect for product managers, growth strategists, UX designers, behavioral scientists, and anyone serious about building products that resonate, retain, and inspire action.
Because at the heart of every great product is a human.

Since blockchains are increasingly adopted in real-world applications, it is of paramount importance to evaluate their performance across diverse scenarios. Although the network infrastructure plays a fundamental role, its impact on performance remains largely unexplored. Some studies evaluate blockchain in cloud environments, but this approach is costly and difficult to reproduce. We propose a cost-effective and reproducible environment that supports both cluster-based setups and emulation capabilities and allows the underlying network topology to be easily modified. We evaluate five industry-grade blockchains Algorand, Diem, Ethereum, Quorum, and Solana across five network topologies fat-tree, full mesh, hypercube, scale-free, and torus and different realistic workloads smart contract requests and transfer transactions. Our benchmark framework, Lilith, shows that full mesh, hypercube, and torus topologies improve blockchain performance under heavy workloads. Algorand and Diem perform consistently across the considered topologies, while Ethereum remains robust but slower.How Psychology Can Power Product Decisions: A Human-Centered Blueprint- Shray...

This contribution presents the integration of the EO Application Package model into the ILIAD Digital Twin of the Ocean architecture, using the OGC API Processes DRU specification. Built on the EOEPCA framework and OGC best practices and specifications, the approach enables standardized, containerized EO applications packaged with CWL to run across a wide range of infrastructures including Kubernetes and HPC. These applications are already in use across several platforms, and in ILIAD they have been applied to models such as oil spill forecasting, aquaculture, wave energy, and ship routing.
The EDITO platform supports OGC API Processes but is currently optimized for simpler workflows using environment variables. To enhance compatibility with EO Application Packages, ILIAD introduces a Kubernetes-based ADES implementation, enabling dynamic execution and integration with EDITO's object store and metadata catalog. The experience is also informing the evolution of the OGC Best Practice, and practical solutions for bridging architectural gaps will be discussed.What is Skeleton system.pptx by aahil sir

science, any system of knowledge that is concerned with the physical world and its phenomena and that entails unbiased observations and systematic experimentation. In general, a science involves a pursuit of knowledge covering general truths or the operations of fundamental laws.
Science can be divided into different branches based on the subject of study. The physical sciences study the inorganic world and comprise the fields of astronomy, physics, chemistry, and the Earth sciences. The biological sciences such as biology and medicine study the organic world of life and its processes. Social sciences like anthropology and economics study the social and cultural aspects of human behaviour.
Science is further treated in a number of articles. For the history of Western and Eastern science, see science, history of. For the conceptualization of science and its interrelationships with culture, see science, philosophy of. For the basic aspects of the scientific approach, see physical science, principles of; and scientific method.
