What is the force between two charges of +5.0 x 10^(-8) C and -1.0 x 10^(-7) C if they are 5.0 cm apart

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

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?

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
