The Earth's atmosphere at sea level and under normal conditions has a pressure of 1.01x105 Pa, which is due to the weight of the air above the ground pushing down on it. How much force due to this pressure is exerted on the roof of a building whose dimensions are 12.7 m long and 11 m wide?

Under normal circumstances, the vitreous humor, a jelly-like substance in the main part of the eye, exerts a pressure of up to 24 mmmm of mercury that maintains the shape of the eye.   If blockage of the drainage duct for aqueous humor causes this pressure to increase to about 50 mm of mercury, the condition is called glaucoma. What is the increase in the total force (in newtons) on the walls of the eye if the pressure increases from 24 mm to 50 mm of mercury? We can quite accurately model the eye as a sphere 2.2 cm in diameter. Express your answer in newtons.

At a given instant, the blood pressure in the heart is 1.7 x 104 Pa. If an artery in the brain is 0.46 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow.

In a tornado or hurricane, a roof may tear away from the house because of a difference in pressure between the air inside and the air outside. Suppose that air is blowing across the top of a 1820 ft2 roof at 167 mi/h. What is the magnitude of the force on the roof? (The density of air is 1.29 kg/m3)

Atmospheric pressure is about 1.00 × 105 Pa on average. What is the downward force of the air on a desktop with surface area 1.01 m2?

The Earth's atmosphere at sea level and under normal conditions has a pressure of 1.01x105 Pa, which is due to the weight of the air above the ground pushing down on it. How much force due to this pressure is exerted on the roof of a building whose dimensions are 10.2 m long and 14.5 m wide?

An automobile weighing 1.19 x 104 N has weight equally distributed over its wheels. The weight of the car causes each tire to be slightly flattened on the bottom so that there is a surface area in contact with the road. The gauge pressure of the air in the tire is 1.90 x 105 Pa (27.55 lb/in2). Find the area of contact, assuming that the only forces on the section of tire in contact with the road are the air pressure and the normal force exerted by the surface of the road.

A 72.0-kg man lies on his back on a bed of nails, with 1,202 of the nails in contact with his body. The end of each nail has area 1.14 ✕ 10−6 m2. What average pressure is exerted by each nail on the man's body?

At a given instant, the blood pressure in the heart is 1.1 x 104 Pa. If an artery in the brain is 0.38 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow. Number Type your answer here Units Choose your answer here

At a given instant, the blood pressure in the heart is 1.4 x 10^4 Pa. If an artery in the brain is 0.49m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow.
