A marble rolls along the floor with a constant velocity of 6 m/s. How far will it have gone after 130 seconds

0.046

Explanation:

displacement = velocity/ time

d = 6m/s / 130s

d = 0.046m

for this one it would be d bump/forearm pass

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 .
