The document discusses atmospheric pressure and the measurement of gas pressures. It explains that Torricelli first demonstrated atmospheric pressure using mercury in a barometer in 1643. The document also outlines Boyle's law that at a constant temperature, the pressure and volume of a gas are inversely proportional. Finally, it discusses manometers as devices used to measure gas pressures.

Daniel Bernoulli discovered Bernoulli's principle in the 1700s through experiments observing water flow. Bernoulli's principle states that as the speed of a fluid increases, the pressure decreases. It explains that the pressure is lowest where the flow speed is highest. Some applications of this principle are how aircraft wings generate lift through differences in air pressure above and below the wing, and how ventilation works through higher pressure pushing lower pressure areas.

Bernoulli's PrincipleEngr.Muhammad Zaroon

Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure. The principle was introduced by Daniel Bernoulli in 1738 and describes the behavior of incompressible, non-viscous fluids. It explains various phenomena like aircraft lift, spoiler function, tennis ball motion, and carburetor/venturi tube operation. The document covers the theory, equation, and various applications of Bernoulli's principle.

Daniel Bernoulli discovered Bernoulli's principle in the 18th century while studying water flow through containers. Bernoulli's principle states that as the velocity of a fluid increases, the pressure within the fluid decreases. Some applications of Bernoulli's principle include venturi tubes, perfume sprayers, pitot tubes, the curved path of spinning balls, and the lift force created by airplane wings. The presentation provided examples of how Bernoulli's principle explains these phenomena in fluids and discussed its importance.

Nearly 150 million kilometers separate the sun and earth, yet solar radiation drives earth's weather and atmosphere. Most atmospheric gases extend only 30 km above the surface, where most weather occurs within the lower 10-15 km. The greenhouse gases of water vapor and carbon dioxide warm the atmosphere by absorbing and emitting infrared radiation. Human and natural activities release aerosols and pollutants into the atmosphere that impact weather and climate patterns. Meteorologists study weather using both satellite instruments that observe large-scale patterns and ground-based tools that measure local conditions.

Bernoulli's principle states that an increase in the speed of a fluid results in a decrease in pressure. It is named after Daniel Bernoulli and can be expressed by the Bernoulli's equation: P + 1/2mv^2 + mgh = constant. Some applications of Bernoulli's principle include: 1) The lift of airplane wings, which occurs because the shape of the wings causes faster moving air over the top surface, resulting in lower pressure lifting the plane. 2) The curved path of a spinning baseball, which results from higher pressure on one side of the ball pushing it in that direction. 3) Atomizers use Bernoulli's principle to create a fine spray by drawing liquid up through a nozzle using

The document discusses concepts related to light, shadows, and reflection. It defines key terms like luminous intensity, luminous flux, and illumination. It explains how shadows are formed from a point light source and how the shadows would look from two point sources or a circular source. It also covers image formation using plane mirrors, the difference between real and virtual images, and how to draw images formed in mirrors.

Bernoulli's principle states that as the speed of a moving fluid increases, the pressure within the fluid decreases. It explains how drinking straws work by describing that the air above the liquid in the straw moves faster than the air below, creating lower pressure and suction. An airplane wing is curved at the top to make the air above it move faster according to Bernoulli's principle, and the lower pressure helps lift the plane.

The document discusses various concepts related to liquid pressure including: - Pressure in a liquid increases with depth and acts equally in all directions. - The greater the density of the liquid, the greater the pressure at a certain depth. - Liquid pressure does not depend on the shape, size, or surface area of its container. - Pressure can be calculated using the formula P = hdg, where h is the height of the liquid, d is the density, and g is acceleration due to gravity.

The Solar System’s passage through the Radcliffe wave during the middle MioceneSérgio Sacani

��

As the Solar System orbits the Milky Way, it encounters various Galactic environments, including dense regions of the interstellar medium (ISM). These encounters can compress the heliosphere, exposing parts of the Solar System to the ISM, while also increasing the influx of interstellar dust into the Solar System and Earth’s atmosphere. The discovery of new Galactic structures, such as the Radcliffe wave, raises the question of whether the Sun has encountered any of them. Aims. The present study investigates the potential passage of the Solar System through the Radcliffe wave gas structure over the past 30 million years (Myr). Methods. We used a sample of 56 high-quality, young (≤30 Myr) open clusters associated with a region of interest of the Radcliffe wave to trace its motion back and investigate a potential crossing with the Solar System’s past orbit. Results. We find that the Solar System’s trajectory intersected the Radcliffe wave in the Orion region. We have constrained the timing of this event to between 18.2 and 11.5 Myr ago, with the closest approach occurring between 14.8 and 12.4 Myr ago. Notably, this period coincides with the Middle Miocene climate transition on Earth, providing an interdisciplinary link with paleoclimatology. The potential impact of the crossing of the Radcliffe wave on the climate on Earth is estimated. This crossing could also lead to anomalies in radionuclide abundances, which is an important research topic in the field of geology and nuclear astrophysics.

��

Iron oxide-hydroxide minerals in Martian dust provide crucial insights into Mars’ past climate and habitability. Previous studies attributed Mars’ red color to anhydrous hematite formed through recent weathering. Here, we show that poorly crystalline ferrihydrite (Fe5O8H · nH2O) is the dominant iron oxidebearing phase in Martian dust, based on combined analyses of orbital, in-situ, and laboratory visible near-infrared spectra. Spectroscopic analyses indicate that a hyperfine mixture of ferrihydrite, basalt and sulfate best matches Martian dust observations. Through laboratory experiments and kinetic calculations, we demonstrate that ferrihydrite remains stable under present-day Martian conditions, preserving its poorly crystalline structure. The persistence of ferrihydrite suggests it formed during a cold, wet period on early Mars under oxidative conditions, followed by a transition to the current hyper-arid environment. This finding challenges previous models of continuous dry oxidation and indicates that ancient Mars experienced aqueous alteration before transitioning to its current desert state.
