Strong winds can apply a significant enough force to tall skyscrapers to set them into a back-and-forth motion. The A of these motions is greater at the higher floors and barely observable for the lower floors. It is said that one can even observe the vibrational motion of the Sears Tower in Chicago on a windy day. As the Sears Tower vibrates back and forth, it makes about 8.6 vibrations in 60sec. Determine the frequency and the period of vibration.

Heat is allowed to flow out of an ideal gas at constant volume so that it's pressure drops from 2.2atm to 1.4atm. Then the gas is expanded at constant pressure from a volume 6.8L to 9.3L until the temperature reaches it's final value.what is the total work done by the gas in the process,the internal energy of the gas and the total flow of heat into or out of the gas.
