Answer:
The energy of the capacitors connected in parallel is 0.27 J
Given:
C = 
C' =
Potential difference, V = 300 V
Solution:
Now, we know that the equivalent capacitance of the two parallel connected capacitors is given by:

The energy of the capacitor, E is given by;


Answer:
43.96 L
Explanation:
We are given that





We know that


Substitute the values


Hence, the volume of balloon at -14.8 degree Celsius=43.96 L
