We start with 5.00 moles of an ideal monatomic gas with an initial temperature of 129 โC. The gas expands and, in the process, absorbs an amount of heat equal to 1180 J and does an amount of work equal to 2160 J . What is the final temperature Tfinal of the gas? Use R = 8.3145 J/(molโ K) for the ideal gas constant.

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ํ
=0.381meters and mass ํ=3.1ํํ. initially ํ"is on the ground and ํ#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ํ#just before it strikes the ground. assume the pulley bearing is frictionless.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
