M1 v1 = (m1 + m2)v2.
All of the exponents should be lowered to the bottom right of the letters.
Answer:
Water gains energy during evaporation and releases it during condensation in the atmosphere
Explanation:
In the water cycle, heat energy is gained or lost by water as it undergoes various processes in the cycle.
In evaporation, water molecules gains energy because the molecules of water vibrate faster and become more energetic. Hence they are able to escape into the atmosphere from the surface of the liquid.
In condensation, the molecules of gaseous water looses energy and becomes liquid.
Hence, water gains energy during evaporation and releases it during condensation in the atmosphere.

Answer:
Explanation:
The function of the current with respect to time is the derivative of the charge function with respect to time t. We can apply chain rule to differentiate it:
A conservation law is law on a certain measurable property that is said to not change as the system undergo changes over a certain time. These laws include, conservation of mass, energy and momentum. The basic approach for these laws is to make balances and make sure the flow in is equal to what is going out the system.<span />
