Atmospheric pressure is the force per unit area exerted on a surface by the weight of air above that surface in the atmosphere of Earth (or that of another planet). In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the mass of air above the measurement point. Low-pressure areas have less atmospheric mass above their location‚ whereas high-pressure areas have more atmospheric mass above their location. Likewise‚ as elevation increases‚ there is

Synthesis Essay: Pressures of Society My topic focuses on societal pressures on celebrities and people. While research may confirm that both celebrities and people have the same problems‚ you can’t help but notice that celebrities are more judged. This is a highly controversial topic because we are so quick to judge someone based on their actions without really knowing them. While some people think celebrities are a bad influence some still think they can also have some benefits to the community

The crew live and work inside the pressure hull. It must be strong enough to withstand the pressure of the water at the depth the submarine is designed to operate. When the air tanks are full of air the submarine will float - usually submarines are designed to float on the surface quite low in the water (only a little freeboard). When the submarine dives (submerges) water is let into the tanks; to surface again air is blown into them. This air must be stored inside the submarine in compressed air

(a) Give generalized conclusions (in point form) according to your observation in (a). 1. systolic pressure increases when the degree of exercise increases Systolic pressure increases gradually from 115 mmHg at rest to 150 mmHg during severe exercise. When thr degree of exercise increases‚ the skeleton muscle needs more energy(ATP) for rapid contraction by carrying out aerobic respiration. The skeleton muscle required faster uptake of oxygen and removal of carbon dioxide. At the same time‚ skeleton

Peer Pressure “Come on grab it hurry just grab it‚ it’s easy to steal the video game and I will let you play it first hurry‚ and grab it.” Peer pressure is basically someone around you who is trying to get you to do something you are not comfortable with‚ or something that is against your standards.

“There Will Be Blood” Let me begin by saying that the movie‚ “There Will Be Blood‚” was completely different than I had originally thought it would be. I knew very little about the storyline of the movie and had very little background information. I guess all I really presumed what that ‘there would be blood;’ which did not happen much either. Almost immediately after beginning the film‚ I was less than amused by the look of it. The plot begins in a desolate field; no people‚ just music. I had

Blood‚ cerebrospinal fluid (CSF) and brain tissue are all constituents of the cranium. The pressure within the cranium is known as intracranial pressure (ICP); it is the same as that found in the brain tissue and CSF. (2) The pressure-volume relationship between ICP‚ brain tissue‚ blood‚ volume of CSF‚ and cerebral perfusion pressure (CPP) is known as the Monro-Kellie hypothesis.(12) This hypothesis states that the cranial compartment is considered as an enclosed and inelastic container‚ which has

A pressure gauge is an instrument that measures the pressure in a vessel‚ a line‚ or whatever the pressure gauge is connected to. A Bourdon gauge consists of a C-shaped pipe with one end closed and the other end attached to a chamber whose pressure is being measured. When there is a pressure difference between the inside of the pipe and the outside‚ there will be a net force acting on the C-shaped pipe which will either try to curl the pipe into a tighter C shape (if the pressure in the pipe is
