    A water balloon is dropped from the top of the Physics building. Assume the balloon does not break when it strikes the ground. a) Create a particular model for this phenomenon by making an energy-system diagram for the process that takes place from the time the water balloon is dropped until it is motionless on the ground. (Hint: consider the indicators to determine what energy systems must be present/can be excluded. Have you included enough systems?) b) If the water balloon is...

    (4) Thermodynamic data suggests that copper monohalides (CuX) should exist as polymers in the gas phaso However, scientists have successfully synthesized CuX monomers and characterized them using microwave spectroscopy For Cu Br the J-13 14,J-1415 and J-1516 transitions occurred at 84421.34 MHz, 90449.25 MHz and 96476.72 MHz, respectively. Assuming Cu Br behaves as a 3D rigid rotor, answer the following questions. Note: Absorption frequency (in units of Hz) of a rotational transition (aka peak position in a microwave spectrum) corresponding...
