What mass of silver has a volume of 150 cm3? A certain gas has a volume of 600 cm3. What is its volume when the pressure is tripled? Consider the gas in # 5 above. What is its volume if the pressure is changed to one-third its original value?

A water tank of height h has a small hole at height y. The water is replenished to keep h from changing. The water squirting from the hole has range x. The range approaches zero as y → 0 because the water squirts right onto the ground. The range also approaches zero as y → h because the horizontal velocity becomes zero. Thus there must be some height y between 0 and h for which the range is a maximum. (Figure 1) Figure h y < 1 of 1 Part B Find an algebraic expression for the range of a particle shot horizontally from height y with speed v. Express your answer in terms of the variables v, y and appropriate constants. ► View Available Hint(s) VE ΑΣΦ x = Submit Previous Answers Request Answer ?

The figure below shows a gas contained in a vertical piston–cylinder assembly. A vertical shaft whose cross-sectional area is 0.8 cm2 is attached to the top of the piston. Determine the magnitude, F, of the force acting on the shaft, in N, required if the gas pressure is 3 bar. The masses of the piston and attached shaft are 24.5 kg and 0.5 kg, respectively. The piston diameter is D = 10 cm. The local atmospheric pressure is 1 bar. The piston moves smoothly in the cylinder and g = 9.81 m/s2.

A tank with a volume of 0.100 m3 contains helium gas at a pressure of 150 atm. How many balloons can the tank fill if each balloon is a ball with a diameter of 0.300 m and a pressure of 1.20 atm?
