Answer:

10

Explanation:

Each time you want to move up the scale, the number is multiplied by 10. The opposite is true when moving down; you must divide by 10.

A large container contains a large amount of water. A hole is drilled on the wall of the container, at a vertical distance h = 0
hammer [34]

Speed can be found through the application of concepts related to potential energy and kinetic energy, for which you have

KE = PE

\frac{1}{2}mv^2 = mgh

Where,

m = mass

v = Velocity

g = Gravitational acceleration

h = Height

Re-arrange to find the velocity we have,

v^2 = 2gh

v = \sqrt{2gh}

v = \sqrt{2(9.8)(0.54)}

v = 3.253m/s

Therefore the speed at which water squirts out of the hole is .3253m/s

A billiard ball collides with a second identical ball in an elastic head-on collision. What is the kinetic energy of the system
murzikaleks [220]

Answer:

Explanation:

From the question, we were made to understand that the collision between the two billiard balls was an elastic collision. Hence, an elastic collision is one in which the kinetic energy is conserved. Meaning the kinetic energy before the collision is still retained after the collision.

Kinetic energy before collision = kinetic energy after collision

1/2mv^2 = 1/2mv^2

There was no gain nor loss in energy

A runner of mass 80 kg is moving at 8.0 m/s. Calculate her kinetic energy. ​
lana [24]

Answer:

2560J

Explanation:

By definition the kinetic energy can be calculated in the following way:

K = (mv²)/2 = 80kg·(8.0m/s)²/2 = 2560 J
