Adentist's drill starts from rest. after 3.50 s of constant angular acceleration, it turns at a rate of 2.49 104 rev/min. (a) find the drill's angular acceleration. incorrect: your answer is incorrect. your response differs from the correct answer by more than 10%. double check your calculations. rad/s2 (along the axis of rotation) (b) determine the angle through which the drill rotates during this period. rad

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
