after pedro had breakfastтАЪ he went for a run. identify at least three energy transformations that had to take place to allow pedro to complete his run. then use evidence to support the claim that energy in hia system was conserved as it was transformed.

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 .

chemical properties of thing

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
