Two negatively charged objects A and B are charged and create an electric field. The electric field strength at a point precisely midway between these two charges is 10 N/C, directed leftward. This provides evidence that .

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. (0.00644 kg/s, 800 kpa, 2.03)

How does changing the frequency affect the energy of the wave?
