0.85 x 45 x 128 = 4896
Change in energy = specific heat capacity x mass x change in temperature
Answer:
383.6 nJ
Explanation:
The energy stored in a capacitor is given by the formula:

where
C is the capacitance
V is the voltage applied
In this problem, we have
C = 14.8 nF is the capacitance of the capacitor
V = 7.2 V is the voltage
Substituting into the equation, we find:
