Why are all the different parts of the cell necessary?
answer

All the different parts of a cell are necessary because they all work together for a common goal. If even one of them goes wrong, it will throw off the tasks and movements of the others. This will cause damage to the cell. Hope this helps :)

i will answer your question if you answer mine

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
