How strong is the repulsive force exerted on two point charges that each carry 1.0 e-6 c of negative charge and are 0.30 meters apart? coulomb’s constant is 9.0 e9 n*m^2/c^2 remember to identity all of your data, write the equation, and show your work.

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?
