Planet Nine is speculated to be on average 20 times farther away from the Sun than Neptune (on average distance from the Sun). How many miles from the Sun would this place Planet Nine on average? Divide 93 million miles into your result to get how many astronomical units (AU) Planet Nine would be on average away from the Sun.

The two required components for a generator

The least penetrating form of radiation is

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.
