Answer:
Force,
Explanation:
Given that,
Charges on pith balls,
Distance between balls, d = 9 cm = 0.09 m
Let F is the repulsive force between two pith balls. We know that the repulsive force between two charges is given by :
F = 0.000871 N
or
So, the repulsive force between the pith balls is . Hence, this is the required solution.
Answer:
Explanation:
Given
COP= 60 % of carnot heat pump
For heat added directly to be as efficient as via heat pump
False I think
Hope this helped ^^;
Because these materials have relatively small gap compare to insulator
