An object is casting a shadow on the ground If an object is 85 feet shorter than the length of the shadow on the ground and the tip of the Shadow is 125 feet from

the top of the object, how tall is that object?

The object is

tall

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

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )
