Answer:
True
Explanation:
Whenever electrons are transferred between objects, neutral matter becomes charged. For example, when atoms lose or gain electrons they become charged particles called ions. Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same.
I tried, hope this helps :)
* I might be wrong though
The amount of force exerted is 77.7N
<u>Explanation:</u>
Given:
Work done, W = 350J
Distance, x = 4.5m
Force, F = ?
We know,
Work = force X distance
350 = F X 4.5m
F = 77.7N
Therefore, the amount of force exerted is 77.7N
