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the locking pin p. calculate the angular acceleration of the frame a if the locking pin is (a) in place and (b) withdrawn.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.

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
