We place a 1 mole sample of an ideal monatomic gas in a cylinder with a piston and we heat the gas so it expands and performs work against the piston. Suppose the temperature of the gas increases by 89 celcius while at the same time it performs 700J of work.
a) what is the change of the internal energy of the gas in this process?
b) How much heat does the gas absorb during the process?
If so evaluate their acceleraton and the tension in the string. If not determine the sum of the magnitudes of the forces of friction acting on the blocks.
A solid, frictionless cylindrical pulley with a mass of 3kg and a 0.420 m radius is used to draw water from a well. A 1.50kg bucket is attached to a cord that is wrapped around the pulley. If the bucket starts from rest at the top of the well and ..
