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.

1) A tiger leaps horizontally from a 7.5 m high rock with a speed of 4.5 m/s. How far from
Artyom0805 [142]

The distance of tiger's leap from the base of rock is 5.58 m

It is a question of two dimensional motion

The time of motion in two dimensional motion is given by:

t= \sqrt{2y/g}

where y is the height and g is  the acceleration due to gravity

y is given to be 7.5m and let us assume g to be 9.8 m/s^2

t = \sqrt{2 * 7.5/9.8}

 = 1.24s

Using time and speed,

We know that distance is the product of speed and time,

Distance= speed x time

speed is given to be 4.5 m/s

distance from the base of rock = 4.5 x 1.24

                                                    = 5.58m

Hence the distance of tiger's leap from the base of rock is 5.58 m

Disclaimer:

The acceleration due to gravity is assumed to be 9.8 m/s^2
