Properties and chemical reactions edmentem notes answers

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 .

another example of kinetic energy would be,

kinetic energy   >     moving energy
