How are AC and DC generators different? In AC generators, commutators produce alternating current. In AC generators, no commutators or slip rings are used. In DC generators, slip rings produce direct current.

A 30.0-kg object experiences a drag force due to air resistance with a magnitude proportional to the square of its speed. The object falls with an acceleration of 4.00 m/s2 downward when it is falling downward at 70.0 m/s.

If a tank contains water 4 m deep, what is the pressure at the bottom of the tank? (Neglect the atmospheric pressure.)
