A cylinder contains 3.5 {\rm L} of oxygen at350 {\rm K} and 2.4 {\rm atm}. The gas is heated, causing a piston in the cylinder to move outward. The heating reasons the temperature to rise to 610 {\rm K} and the volume of the cylinder to increase to 9.2 {\rm L}.
What is the gas pressure?
Would a plucked guitar sting vibrate for a longer time or a shorter time if the instrument had no sounding board? explain.
How far is he from the orgin. A simple pendulum has a mass of 0.350 kg and a length of 2.00 m. It is displaced through an angle of 7.0° and then free.
