Draw a circuit that has a battery, a lightbulb, and connecting wires. Draw a schematic of a water flow system that allows a continual circulation of water and compare the function of each element of the circuit to each element of the water flow system.

Explanation:

In an electrical circuit the potential difference is the driving force for the motion of the charges similarly in a water flow system the pressure difference is the driving force for the flow of water.

In electrical circuit the wires carry the charges while in the water flow system the pipe carries the water.

In electrical circuit a battery generates the potential difference while in the water flow system the pressure difference is created using a pump.

In electrical circuit the light bulb is an output device while in a water flow system the tap or a nozzle can be an output device.

In electrical circuit the rate of flow of charge is called current while in the water flow system the volume flow rate of water is called discharge.

yup its correct its: c) b b

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.
