If Brett and Chris are trying to move a piano and Brett pushes the piano with 25 N of force and Chris pulls the piano in the same direction with 20 N of force what is the net force

45 N

Explanation:

From the question given above, the following data were obtained:

Force applied by Brett = 25 N

Force applied by Chris = 20 N

Net force =?

From the question given above, Brett and Chris applied force to the piano in the same direction. Thus the net force acting on the piano will be the sum of the forces applied by Brett and Chris. This can be obtained as follow:

Force applied by Brett = 25 N

Force applied by Chris = 20 N

Net force =?

Net force = 25 + 20

Net force = 45 N

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
