OPEN, INTERRUPTION,  CLOSED

Explanation:

In this exercise, you are asked to complete the expression with the correct words.

Let's resist an important concept when a circuit has a path leaving a point and can return to the same point, it is said that the circuit is closed and current can circulate.

Now let's complete the expression is

The bulb is not on because the switch is__OPEN_

and there is a_INTERRUPTION___in the circuit.

The bulb will come on if you_CLOSED__

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
