Aballoonist drops an apple weighing 1.5n over the side of the balloon's gondola. as it falls and increases speed, the drag force from the air upward on it increases. when the upward force is 0.7n, what is the direction and magnitude of the net force on the apple?

i'm not sure what to do with the 1.5n weight of the apple. should i convert it to mass using its assumed weight on earth?

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.
