How does Newton’s third law of motion apply to a marble rollercoaster model?? I’m making a model rollercoaster with a marble as the car and I’m supposed to do a presentation on the three laws of motion and how they apply to our rollercoaster specifically. How does it apply to a marble rollercoaster? Not a real one a model one. As in it can’t be about you being thrown around in your seat.

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.
