ALL PHYSICS DOUBTS - POST HERE !!
Ashe:
I don't really understand why we use a relay in circuits. When they ask why a relay is used in a circuit? what's the full answer to that?
And another question, i saw this in a past paper but couldnt find it again =S
When someone is driving in a car, and the car suddenly crashes. What's the energy change of the driver?
I know its from kinetic, but into what?
eastrimx:
