Consider each of the electric- and magnetic-field orientations given next. in each case, what is the direction of propagation of the wave? (a) e in the +x-direction, b in the +y-direction; (b) e in the -y-direction, b in the +x-direction; (c) e in the +z-direction, b in the -x-direction; (d) e in the +y-direction, b in the -z-direction.

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)

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.
