A light string is wrapped around a solid uniform disk of radius 25.0 cm and mass 0.500 kg. The pulley is initially rotating at 5.00 rad/s. A constant force of 30.0 N is applied to the string, which does not slip, causing the pulley to rotate and the string to unwind. The torque exerted by friction at the axle has a magnitude of 5.00 N-m. Part A Find the angular acceleration of the disk. Express your answer with the appropriate units. Part B Determine the angular velocity of the disk after a time of 0.300 S. Express your answer with the appropriate units. Part C In radians, find the angular displacement of the disk in that time. Input your numerical answer.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
