Answer:
600Joules
Explanation:
The energy stored by this battery is calculated using the energy formula;
E = Q× v
Where E is energy
Q is the charge
v is voltage
Hence E = 50 × 12 = 600Joules
Note Q = 12 ampere minute
Not sure but just coming to say good luck and take your time

Answer:
i = 101.4A
Explanation:
The steps to the solution can be found in the attachment below.
We have been given the frequency f = 60Hz. From this we can calculate the angular frequency of the power line.
It is assumed that sinwt = –1 in order to calculate the time varying current. Although the magnitude of the current is large, consideration should also be given to the distance between the coil and the power line. The induced emf is small considering the area of the coil which is 7.85×10-⁵m².
Answer: A
Explanation:
Parallel circuit. The source current is three times the current of a single bulb
