One mole of n2gas (m = 28u) is confined to a container at temperature t = 387 k. assume the molecules both rotate and vibrate. a) what fraction of the molecules has translational kinetic energy within +/- 1% of the average kinetic energy? b) find the total internal energy.

what was the answer?

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.
