Give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs.

There are many examples of momentum in day to day life. As two objects collide the energy remains same after collision as it was before collision.

Momentum can be defined as the quantified motion of an object. As soon as two objects collide the energy of the objects combine.

Suppose there are two balls that collide having momentum m 1 and velocity v 1 and another ball with momentum m 2 and velocity v 2 and after collision then total momentum is M V that is equal to the sum of m1 v1 + m2 v2.

This states the total energy before and after collision remains same(MV)

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
