Abiker rides on an upward-sloped road inclined at a 15.0° angle with the horizontal. if he moves at a constant speed of 2.0 meters/second for 60 seconds, what is the magnitude of his horizontal displacement? 3 meters 116 meters 60 meters 130 meters | | | v=2.0m/s | |=15 degrees v2

With total velocity , the horizontal component of velocity is

Then the horizontal displacement over the first minute is

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 .
