A) When a charge is moved in an electric field the work done (W) is calculated as charge*(change in potential). We can write W = q*V or V = W/q = 10/1 = 10V . This voltage is a difference in electric potential between 2 points within the field. If the charge is positive, and positive work is done upon it, then the final position is more positive than the original one.
<span>b) If a charge (Q) is released from rest and falls through a potential difference V, then its gain in energy (KE if no other force acts on the charged body) is q*V = 10J. This is the same as the work done in moving the charge to its new position in part (a), and is an example of the conservation of energy.</span>

Answer: c) 0
Explanation:
Work tension is zero because in any infinitesimal time interval, the tension force is directly perpendicular to the displacement.
Answer:
advantages of using renewable energy resource
it is safer and cleaner
it does not produces green house gas and has 0 carbon emission
for producing electricity we use solar and wind power that does not harm the environment
advantages of using non renewable energy resource
they are abundant
they are affordable
easy to use
they are easily accessible and compatible
easy to store
1) The heat added to system
2) 800J
3) I'm not sure but I think it would be 300J.. Not certain tho
