Work equal to 136.0 Joules is expanded in moving 8.5*10^18 electrons between two points in an electric circuit. What potential difference does this estabilish between the two points? A ball is thrown into the air. At the highest point, the ball has zero velocity and zero acceleration. Is it true or false and why?

Sagot :

Voltage = joules/coulomb

1 coulomb = 6.25 x 10^18 electrons
8.5 x 10^18 electrons = 1.36 coulombs

136 joules / 1.36 coulombs = 100 volts
===================================
The statement regarding the ball is false. Any object that's not hanging from something
or resting on something is accelerating downward on account of gravity. No matter what
direction you throw the ball, or how hard, its acceleration is 9.8 meters per second^2
directed downward, from the instant it leaves your hand until it hits the ground.
