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

Which changes of state do the labels represent? a: b: c:

The speed of light can be used to measure the

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator.
