Answer and Explanation:
The principle of constant proportion also referred to as Forchhammer's principle states that although the salinity of various samples of seawater may vary, the ratio of major salts present in the sea water remains same irrespective of the salinity of different samples of sea water that might undergo variation in their salinity.
He clarified that the saltiness of seawater changes because of expansion of freshwater and not because of that the proportion of significant salts like sodium chloride, potassium nitrate, magnesium sulfate changes.
Here, if the salt mentioned is NaCl , at that point we can get the measure of NaCl just by estimating saltiness and taking its product with the extent/level of NaCl that is consistent for ocean water to get the sum.
There are various strategies to quantify salinity like by estimating resistivity or the amount of chlorine present in water.
So, if we need to know the measure of NaCl, we can ascertain by this procedure and here is the importance of Law of constant proportion that as the proportions are equal we can utilize that proportion to figure a specific ion.

The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor.
Answer:
A. The movement of the Earth along its orbit
Explanation:
The moon orbits the Earth once every 27.3 days. This is the sidereal month. It is measured against the background stars.
However, the Earth is also orbiting the Sun, and the moon needs extra time to catch up to its previous position relative to the Sun. This is the synodic month. It takes 29.5 days.
B is wrong. The rotational speed of the Earth constant. It makes one revolution every 23 h 56 min 4.09053 s.
C is wrong. The synchronous rotation of the moon does not affect its orbital speed.
D is wrong. The tilt of the Earth's axis affects only the moon's angle in the sky.
