Massless rope

Two blocks of mass m and 3m are slug over a pulley by a massless rope. The massess are initially at the same height. The pulley is a uniform solid disk of mass 12m and radius R. The total length of the rope including the part that is slung over the pullley is L The masses are released at time t = 0 Determine the time it takes ...continues

Kinetic energy and rms speed of gas molecules

A cylinder contains a mixture of helium and argon gas in equilibrium at a temperature of 152 degrees Celsius. a) What is the average kinetic energy of each type of molecule (J/molecule)? b) What is the rms speed of each type of molecule? (m/s)

Force of a gas

A sealed cubical container 14.0 cm on a side contains three times Avoagadro's number of molecules at a temperature of 24.0 degrees celsius. Find the force exerted by the gas on one of the walls of the container (N).

Gases and Heat Transfer

A rigid tank contains .42 moles of oxygen. Determine the mass (in kg) of oxygen that must be withdrawn from the tank to lower the pressure of the gas from 42 atm to 27 atm. Assume that the volume of the tank and the temperature of the oxygen are constant during this operation. (in kg) Lead pellets, each of mass 1.60g, are he ...continues
