The formula that relates the 3 variables, namely: mass,
volume, and density is: Density = mass / volume.
Let us identify each variable:
Density - more accurately called the volumetric mass density of a
substance is its mass per unit volume. It is a key concept that examines how
materials communicate in a lot of things, i.e weather, material sciences,
engineering, and other fields of science.
Mass – defined as a property of
a physical body in Physics, and when a net force is applied,
it results to the measure of a specific
object’s resistance to acceleration.
Volume - <span>contained or
occupied by the space of a substance or shape (either by a solid, liquid, gas
or plasma state)</span>
Dry air adjacent to the cloud is entrained air is drier than the air within a cloud. The evaporation occurs in the cloud which cools the air. The cooling of air increases its density and creates a downdraft.
<h3>How clouds are formed?</h3>
A cloud can be described as a mass of ice crystals or water drops suspended in the atmosphere. Clouds can be formed when the water condenses in the atmosphere. The sky possesses some quantity of water vapours and it is invisible to us.
Clouds can be formed when an area of air gets cooler until the water vapour there condenses to liquid form. At this point, the air gets saturated with water vapours.
A cloud can never be perfectly adiabatic. Therefore, after mixing the environmental air with the clouds, its boundaries will not stay well defined and this process is called entrainment.

<span>The distance between the sources of a two point surface
interference determines the number of lines that can be created for the nodal
and anti-nodal lines. When the sources are moved closer together, the number of
lines becomes minimal. Thus, the spaces between the lines become bigger. The
answer to this item is letter A. The spacing increases. </span>
Answer:
C. 100 mph west
Explanation:
Average velocity is total displacement over total time. During the first hour, the average velocity is:
v_avg = 100 mi / 1 hr
v_avg = 100 mph west
Since the velocity is constant, the instantaneous velocity at any time equals the average velocity.
v = v_avg
v = 100 mph west
