Three asteroids have exactly the same amount of mass. the distance from asteroid a to asteroid b is 300 km, the distance from asteroid b to c is 400 km, and the distance from c to a is 100 km. between which two asteroids would the gravitational force be the largest? a). between asteroid a and b. b). between asteroid b and c. c). between asteroid c and a. d). the gravitational force between each pair of asteroids would be the same.

State the right hand rule of the direction of magnetic field in a conductor carrying current

The crank oa rotates in the vertical plane with a constant clockwise angular velocity ω0 of 5.6 rad/s. for the position where oa is horizontal, calculate the force under the light roller b of the 10.6-kg slender bar ab.

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.
