WILL MARK BRAINLIEST Find the gravitational potential energy for a book that weighs 10 N laying on a counter 3.8 m off the ground. Remember to show your work!

Equation for gravitational potential energy (GPE):
GPE = w x h

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

Ammonia enters the expansion valve of a refrigeration system at a pressure of 10 bar and a temperature of 18oc and exits at 6.0 bar. the refrigerant undergoes a throttling process. determine the temperature, in oc, and the quality of the refrigerant at the exit of the expansion valve.
