A lightweight potter's wheel having a moment of inertia of 24 is spinning freely at 40 rpm the potter drops 4.16kg of clay onto the wheel where it sticks a distance 1.2 from the rotational axis. if the subsequent angular speed of the wheel and clay is 32 rpm what is the new moment of inertia

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

the components of a vector are the parts of the vectors that are to each other.
