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
A,c, and d are your answers :)
- Unlike charges attract .
- like charges repel .
There are two types of charges
Namely :
On loosing electrons , a neutral body acquires positive charge .
On gaining electrons , a neutral body acquires negative charge .
The amount of charge present in a body , either positive or negative , is expressed in terms of an integral number of charge of an electron , which is considered the elementary entity of an electric charge .
