When mars is nearest the earth, the distance separating the two planets is 88.6 x 10^5 km. mars is viewed through a telescope whose mirror has a diameter of 45.0 cm. (a) if the wavelength of the light is 600 nm, what is the angular resolution of the telescope? (b) what is the smallest distance that can be resolved between two points on mars?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
