A chain is wrapped around a pulley and pulled with a force of 16.0N The pulley has a
radius of
0.20m. The pulley's rotational
speed increases from 0.0 to 17.0 rev/min in 5.00s. What is the moment
of inertia of pulley ?

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

Another word for electromagnetic energy is a. heat b. force c. matter d. radiation
