An oxygen molecule vibrates so that the distance between its intramolecular bonds changes from 1 Angstrom to 3 Angstrom. This change occurs 1000 times every second. If the average speed of the movement is 100 m/s, and the weight of the molecule is 10^-26 kg, how much energy is produced by these vibrations?
The Attempt at a Solution
KE= 1/2 x 10^-27 kg x 100m/s^2
= 5 x 10^-25 Joules ? (This is not correct, the answer is 1 x 10^-22 Joules)
