The solid cylindrical rotor b has a mass of 52 kg and is mounted on its central axis c-c. the frame a rotates about the fixed vertical axis o-o under the applied torque m = 44 n·m. the rotor may be unlocked from the frame by withdrawing the locking pin p. calculate the angular acceleration of the frame a if the locking pin is (a) in place and (b) withdrawn. neglect all friction and the mass of the frame.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.

An initially unpolarized light if intensity 500 w/m^2 passes through four polarizers. the transmission axis between adjacent polarizers is 45∘. what percentage of the initial intensity is transmitted by the system?
