Find the resistance of a TV: voltage is 200 V current is 2 A.

R = 100 [ohm]

Explanation:

To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance. In this way we have the following equation.

V = I*R

where:

V = voltage = 200 [V] (units of volts)

I = current = 2 [A] (units of amperes)

R = resistance [ohm]

R =V/I

R = 200/2

R = 100 [ohm]

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.
