Two containers, x and y, both contain nitrogen gas at a temperature of 30° c and a pressure of 1 atm. the initial volume of each of the containers is v30 = 0.5 liters. the only difference between the two containers is that while container x has a piston that is sealed and cannot move, the gas in container y is allowed to expand against the surrounding atmosphere. qx is the amount of heat required to raise the temperature of the gas in container x by 10° c, and qy is the amount of heat required to raise the temperature of the gas in container y by 10° c. what is the difference between qx and qy? use 0°c = 273.15 k qx - qy =

true tan speed = ang vel x radius

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
