During the condensation, the water that rise through evaporation will be transformed into liquid form.
During the precipitation, this liquid form will fall to the ground because of gravity, and created what we commonly known as the rain</span>
Answer:
M = 1.994 × 10^(30) kg
Explanation:
We are given;
Orbital radius; r = 1.5 × 10^(8) km = 1.5 × 10^(11) m
Gravitational constant; G = 6.67 × 10^(-11) N.m²/kg²
If the orbit is circular, the it means the gravitational force is equal to the centripetal force.
Thus; F_g = F_c
GMm/r² = mv²/r
Simplifying gives;
GM/r = v²
M = v²r/G
Now, v is the speed of the earth around the sun and from online sources it has a value of around 29.78 km/s = 29780 m/s
Thus;
M = (29780^(2) × 1.5 × 10^(11))/6.67 × 10^(-11)
M = 1.994 × 10^(30) kg
