emily exerts a force of 30 N on the painting in the direction she travels as she first carries it 15 m on a level sidewalk and then climbs 1.5 up the stairs her walk takes 15 s. How much work does emily do on the painting in all

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 .

would be false hope this out
