You are loading a refrigerator weighing 2267 n onto a truck, using a wheeled cart. the refrigerator is raised 1.09 m to the truck bed when it is rolled up a ramp. (assume that there is no frictional force between the refrigerator and the ) calculate the minimum work that must be done by the force you apply and the magnitude of the force if the ramp is at an angle with the horizontal of 45.0°.

First answer marked as brainiest which is the correct equation describing the first law of thermodynamics? a) when the internal energy of a system changes, it equals the amount of heat added plus the work done. b) when work is done by the piston, it is equal to the heat added plus the change in internal energy of the system. c) when heat is added to the system, it is equal to the amount of work done by the piston plus the change in internal energy of the system.
