Consider a simple lifting machine, If a lever of 1,400 N, is lifted by an effort of 50 N, caused the load to move up by 0.2 m, while the effort moved by 6 m. Calculate the velocity ratio of the machine.

From the object at higher temperature to the object at lower temperature

Explanation:

Heat corresponds to the transfer of thermal energy between two objects. Temperature gives a measure of "how much thermal energy an object has": the higher the temperature, the faster the molecules inside the object, the more thermal energy the object has. Therefore, an object at higher temperature has more thermal energy than an object at lower temperature, so the transfer of heat goes from the object at higher temperature to the object at lower temperature.
