Exactly what the first person said. Hope this helps!
Explanation:
An electrical circuit needs:
a source of electrical power (this could be a power plant or a battery)
a material along which the electricity can flow (this may be a copper wire)
something to power (this could be a bulb)
The circuit is connected in a loop. Then, the source of power pushes electrons around the wire. It lights the bulb and continues in the circuit until it is broken.
A simple circuit lights one bulb. More difficult circuits might have several switches and loops. This would allow different groups of lights to be turned on or off at the same time.

The law of conservation of energy states that: "energy cannot be created nor destroyed. It can only be transformed from one form to the other". A heat pump transfers heat from a colder area to a warmer area. As the conservation of energy goes, the energy that comes in, must equal the energy that comes out. Although no machine is 100% efficient, the missing energy is supplied by an external energy source, such as electricity.
Can be absorbed and transformed into heat. i know this because i used to work as a constructor for lights and i had to go over a training on this subject.
Answer:
The Electric field will be 225.92 N/C
Explanation:
Given :
- Radius of the hollow sphere R=42.8 cm
- Initial charge on the conducting sphere is

- Magnitude of the point charge

We know that the flux of the electric field through a close surface cab be calculated by using Gauss Law which is

Hence the Electric Field is calculated.
The answer founded out by you seems to be correct and very close to the exact answer and the concept you have used in your answer is also correct.
