You are inside a chamber of pressure of 1atm, which exerts force of 30,000 N on your body. A child with 40% of your surface area is also inside the chamber. What is the force on the child's body? (The answer is not 7,500 N)
You are inside a chamber with air pressure of 1 atm, which exerts a force of 30,000 N on your body. A child with 10 percent of your surface area is also inside the chamber. What is the force on the child's body? 3000 N The air pressure is increased by 30 percent. What is the new force on your body?
Pumping air into a tire increases the pressure inside because ... ... the volume of air inside the tire is increased, hence air molecules have a greater surface area of tire that they hit, increasing the force on the inside wall of the tire. more air molecules collide with the inside wall of the tire during any given time interval. ... the higher air density in the tire increases the temperature, which is proportional to pressure in this scenario.
QUESTION 3 A 40,000 kg truck is held up by 18 wheels. The air pressure inside of the tires is 60 psi 4.13 X 105 Pa. Suppose that this is also the pressure that the tires exerts on the ground. What is the area of each tire which presses on the ground? 0.072 m2 0.067 m2 0.053 m2 0.032 m2

You and your younger brother are designing an air rifle that will shoot a lead pellet with mass m 1.00 g and cross-sectional area A = 0.0250 cm2. The rifle works by allowing high-pressure air to expand, propelling the pellet down the rifle barrel. Because this process happens very quickly, no appreciable thermal conduction occurs and the expansion is essentially adiabatic. Your design is such that, once the pressure begins pushing on the pellet, it moves a distance of L...
10. Air pressure inside a research submarine is 101,000 Pa. The total pressure outside the submarine is 201,940 Pa. What is the net force on a window with an area of 0.090 m´?
Draw a picture. Show open surfaces, pistons, boundaries, and other features that affect the pressure. Include height and area measurements and fluid densities. Identify the points at which you need to find the pressure. These objects make up the system; the environment is everything else. Determine the pressure at the various surfaces. For a surface open to the air, p0=patmos, usually 1 atm. For a surface covered by a gas, p0=pgas. For a closed surface, p=F/A, where F is the...
In this lab, you will be breathing into a 5 L mixing chamber. The mixing chamber will start with “regular” air (20.93 vol% O2, 0.04 vol% CO2, and 79.03 vol% N2). You will inhale air through your nose (which is exposed to “regular” air) and exhale through your mouth into the mixing chamber. As your exhaled air is added into the chamber, an equal volume of air leaves the other end of the chamber so that the system remains at...
You and your younger brother are designing an air rifle that will shoot a lead pellet with mass m = 1.00 g and cross-sectional area A = 0.0150 cm2. The rifle works by allowing high-pressure air to expand, propelling the pellet down the rifle barrel. Because this process happens very quickly, no appreciable thermal conduction occurs and the expansion is essentially adiabatic. Your design is such that, once the pressure begins pushing on the pellet, it moves a distance of...
