Aballoon is rubbed with a wool glove. the two items attract one another with a force of strength 0.8 n when they are 1 cm apart. if they have equal but opposite charges, what is the magnitude of the charge?

Awind turbine is initially spinning at a constant angular speed. as the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.173 rad/s2. after making 2870 revolutions, its angular speed is 132 rad/s. (a) what is the initial angular velocity of the turbine? (b) how much time elapses while the turbine is speeding up?

Work = force × a. work b. energy c. distance d. momentum
