<u>Answer:</u> The charge on each plates is
.
<u>Explanation:</u>
The magnitude of charge that flows through the plates is directly dependent on the capacitance and the voltage flowing through the plates.
Mathematically,

where,
Q = charge flowing = ? C
C = capacitance =
(Conversion Factor:
)
V = Voltage across the plates = 12 V
Putting values in above equation, we get:

Hence, the charge on each plates is
.
You look up the element in the periodic table. Subtract the atomic number (small number) from the mass number (big number). The answer is the number of neutrons.
Answer:31.3W
Explanation: JUST A FORMULA
P = V*V/R = 120*120/460 = 31.3W
