The gravitational potential energy (G.P.E) of the ceiling fan is 712.95 Joules.
<u>Given the following data:</u>
- Mass of ceiling fan = 7.5 kg
- Height = 0.7 m
<u>Scientific data:</u>
- Acceleration due to gravity = 9.8
To calculate the gravitational potential energy (G.P.E) of the ceiling fan:
<h3>What is gravitational potential energy?</h3>Gravitational potential energy (G.P.E) can be defined as the energy that is possessed by an object or body due to its position (height) above planet Earth.
Mathematically, gravitational potential energy (G.P.E) is given by this formula;
<u>Where:</u>
- G.P.E is the gravitational potential energy.
- m is the mass of an object.
- g is the acceleration due to gravity.
- h is the height of an object.
Substituting the given parameters into the formula, we have;
GPE = 712.95 Joules.

Answer:
0.45 m/s in the negative x-direction
Explanation:
From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum
Momentum, p=mv where m is the mass and v is the velocity
where
is the common velocity,
and
are velocities of magnet moving in positive x-direction and magnet moving in negative x-direction respectively,
and
are masses of magnet moving in positive x-direction and magnet moving in negative x-direction respectively.
Substituting 125 g for and 85 g for
, 7.33 m/s
, -11.9 m/s for
then
Therefore, the velocity of single unit is 0.45 m/s in the negative x-direction
