After 10.0 s, a spinning roulette wheel at a casino has slowed down to an angular velocity of 1.56 rad/s. During this time, the wheel has an angular acceleration of -4.6 rad/s2. Determine the angular displacement of the wheel.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

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 .

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
