The force applied to raise a table to a height of 8m when 120 Joules of work is done is 15 N. That is, Force F = 15N
<h3>
What is Work ?</h3>
Work is the product of force and distance in the direction of force. Work is done on an object when the displacement of the object is in the direction of the force applied. That is,
W = F x S
The S.I unit of work is Joule.
Given that a table to a height of 8m and 120J of work was done. To find the force applies, the parameters to consider are
Make force F the subject of formula from the formula written above. That is,
F = W/S
F = 120 / 8
F = 15 N
Therefore, if the 120 Joule of work is done, the force applied to raise a table to a height of 8m is 15 Newtons.

Answer:
A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.

Answer:
C. It is converted into another form, mainly kinetic energy
Explanation:
Potential energy is energy available to be used in an object that isn't currently moving. When an object begins moving, potential energy becomes kinetic energy.
c. A current is induced in the coiled wire, which lights the light bulb.

What is electromagnetic induction?</h3>
If we kept the bar magnet stationary and moved the coil back and forth within the magnetic field an electric current would be induced in the coil.
Then by either moving the wire or changing the magnetic field we can induce a voltage and current within the coil and this process is known as Electromagnetic Induction and is the basic principle of operation of transformers, motors and generators.
When the magnet shown below is moved “towards” the coil, the pointer or needle of the Galvanometer, which is basically a very sensitive center zeroed moving-coil ammeter, will deflect away from its center position in one direction only.
When the magnet stops moving and is held stationary with regards to the coil the needle of the galvanometer returns back to zero as there is no physical movement of the magnetic field.
Therefore ,
If you move a bar magnet back and forth along the axis of the coiled wire shown below then a current is induced in the coiled wire, which lights the light bulb.
