Answer:
First law of thermodynamics.
Explanation:
The first law of thermodynamics states that the change in internal energy of a system ΔE equals to the amount of heat energy supplied to the system H , minus the work done by the system on its surroundings. W.
The above definition can be expressed mathematically as: ΔE = H - W
This can also be restarted as energy of a close or isolated system is constant.
There is no acceleration of g in the x direction because the gravitational acceleration points downward. Also, on most studies we ignore the tidal forces since we are dealing with small bodies compared to the size of the earth.

The answer is D. Products are formed from reactants by the breaking and forming of new bonds.
Answer:
Raindrops start to form in a roughly spherical structure due to the surface tension of water. This surface tension is the "skin" of a body of water that makes the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules.
