Me, !
suppose the unit horsepower actually replaced watt as the unit of power for electric appliances. what would the power rating of a 500-w refrigerator be in horsepower?
(1 horsepower = 764-w)

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

In the first law of thermodynamics, triangle e=q-w, what does q stand for

How are the crust and the inner core alike? a) they are both solid. b) they both have the same temperature. c) they are both under the same pressure. d) they are both very close to the center of the earth.
