Using the circuit diagram above. Calculate the total charge in the circuit
80μC
35μC
20μC
16μC
Correct answer is D
C - C1+C2=2+6=μF
1C=1C1+1C1+1C2=18+12
C = 85μF
Q = CV
= 85×10=16μC
Nuclear fusion is not used as a source of enegy because
very high temperature is needed for the reaction
the fuel for the reaction is not easy to obtain
less energy is released
the reaction is too slow

1.8 x 10-10J
9.0 x 10-11J
6.0 x 10-19J
1.2 x 10-45J
Correct answer is A
Q = ΔMC2
= 2 x 10-27(3 x 10
= 1.8 x 10-10J
