You want to find the configuration using three capacitors in a circuit that gives you an equivalent capacitance of 2 pf between points x and y. Consider the case when each capacitance is 3 pf.

the answer is b i think

true tan speed = ang vel x radius

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
