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

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
