The figure shows a glass cylinder of radius 6.8 cm, partially filled with oil of density 0.87 × 10³ kg/m³. . Floating freely on top with no oil leaking around the sides, a 2.8-kg wooden disk supports a 0.5-kg potato. Calculate the gauge pressure in psi at 13.6 cm below the surface of the oil. (1 psi = 6.895 kPa) %3D pooM psi (Note the units!) %3D = d

The absolute pressure in your car tires is 3.7 × 105 Pa at a temperature of 35.0°C when you drive it onto a ferry boat to Alaska a. What is the absolute pressure of the tires, in pascals, later when the temperature has dropped to -40.0°C? Assume the volume of each tire does not change.

A cylinder containing ideal gas is sealed by a piston that is above the gas. The piston is a cylindrical object, with a weight of 22.0 N, which can slide up or down in the cylinder without friction. The inner radius of the cylinder, and the radius of the piston, is 8.00 cm. The top of the piston is exposed to the atmosphere, and the atmospheric pressure is 101.3 kPa. The cylinder has a height of 30.0 cm, and, when the temperature of the gas is 20°C, the bottom of the piston is 11.0 cm above the bottom of the cylinder. (A) Find the number of moles of ideal gas in the cylinder. (B) Heat is added, gradually raising the temperature of the gas to 160°C. Calculate the distance between the bottom of the cylinder and the bottom of the piston when the piston comes to its new equilibrium position.

An airplane passenger has 100 cm3 of air in his stomach just before the plane takes off from a sea-level airport. What volume will the air have at cruising altitude if cabin pressure drops to 7.50 X 104 N/m2?

Tire gauges for air pressure, as well as most other gauges used in an industrial environment take into account the pressure due to the atmosphere of earth. That's why your car gauge reads 0 before you put it on your tire to check your pressure. That is called gauge pressure. The real pressure within a tire or other object contains pressurized stuff would be a combination of what the gauge reads as well at the atmospheric pressure. If a gauge on a tire reads 40.16 psi, what is the real pressure in the tire in pascals. The atmospheric pressure is 1.01x10^5 Pa.

The gauge pressure in your car tires is 2.55 × 105 Pa at a temperature of 35.0°C when you drive it onto a ferry boat to Alaska. What is the gauge pressure of the tires, in pascals, later when the temperature has dropped to -40.0°C? Assume the volume of each tire does not change.

determine the atmospheric pressure at a location where the barometric reading is 740 mm hg. Assume the temperature of mercury to be 10 degrees Celsius at which its density is 13570 kg/m3

Water flows at 0.25 L/sL/s through a 7.0-mm-long garden hose 2.5 cmcm in diameter that is lying flat on the ground.  The temperature of the water is 20 ∘C∘C. What is the gauge pressure of the water where it enters the hose? Express your answer in pascals.

A 0.504 kg metal cylinder is placed inside the top of a plastic tube, the lower end of which is sealed off by an adjustable plunger. The cylinder comes to rest some distance above the plunger. The plastic tube has an inner radius of 5.88 mm and is frictionless. Neither the plunger nor the metal cylinder allow any air to flow around them. If the plunger is suddenly pushed upwards, increasing the pressure between the plunger and the metal cylinder by a factor of 3.03, what is the initial acceleration a of the metal cylinder? Assume the pressure outside of the tube is 1.00 atm and that the top of the tube is open to the air.

A 0.458 kg metal cylinder is placed inside the top of a plastic tube, the lower end of which is sealed off by an adjustable plunger. The cylinder comes to rest some distance above the plunger. The plastic tube has an inner radius of 6.90 mm and is frictionless. Neither the plunger nor the metal cylinder allow any air to flow around them. If the plunger is suddenly pushed upwards, increasing the pressure between the plunger and the metal cylinder by a factor of 2.07, what is the initial acceleration a of the metal cylinder? Assume the pressure outside of the tube is 1.00 atm and that the top of the tube is open to the air. a = m/s?
