7. A bike accelerates uniformly from rest to a speed of 7.10 m/s over a distance of 35.4
m. Determine the acceleration of the bike

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 .

a, c, d, e are all applying about success strategies.
