A monatomic ideal gas is contained within a perfectly insulated cylinder that is fitted with a movable piston. The initial pressure of the gas is 1.50 X 105 Pa. The piston is pushed so as to compress the gas with the result that the Kelvin temperature doubles. What is the final pressure of the gas?
A Ferris wheel is moving at an initial angular velocity of 1.0 rev/48 s. If the operator then brings it to a stop in 3.4 min, what is the angular acceleration of the Ferris wheel
A 0.66-kg metal sphere oscillates at the end of a vertical spring. As the spring stretches from0.14 to 0.25 m ( relative to its unstrained length), the speed of the sphere decreases from 6.15 to 4.55 m/s. What is the spring constant of the spring?
