<span>Water in the oceans may become fresh water available to humans through the processes of evaporation, condensation and precipitation.
In these processes, water is heated to a very high temperature until it evaporates in order to kill the germs and remove the salts which remains after water evaporation. The next step in condensing the water vapor (which is now fresh) and precipitating this vapor to be used by humans.</span>
Ans: Thus, the kinetic energy change = 4.5 JThe mass of puppy = 3kg
Kinetic energy initial =
=
Kinetic energy final =
Thus, the kinetic energy change = 4.5 J
Answer:
The value of 
is 
.
Explanation:
Given that,
Number 
Energy difference = 6\times10^{-21}\ J[/tex]
Temperature T =300 K
We need to calculate the value of
We know that,
Hence, The value of is .
Light waves are never 'aborted'.
They can be 'absorbed', and I think that's what you mean.
It's what happens when light hits something or goes into it,
and never comes out.
"Absorb" just means "soak up". When a light wave hits something and
gets soaked up in it, it's gone, and never comes out the other side.
The light wave certainly gets changed ... it no longer exists.
The object that absorbs it also gets changed. It soaks up the energy
in the light wave, and it has a little more internal energy (heat) than it
had before the light hit it.
The answer to that question is c. acceleration due to gravity
