Think and discuss: why do you think the area swept out by a planet in a given period of time remains constant, even as the planet speeds up and slows down? (select all that apply) (hint: think of each area swept out as a triangle. the height of the triangle is the distance between the planet and the sun, while the base of the triangle is equal to the distance the planet travels in the given time period.

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)
