The three conditions that must occur before clouds can form Sufficient water vapor must be present in the air. Water vapor is the invisible gas form of water. It is all around us, even in dry air.
A surface for water vapor to condense on is needed. This is called a cloud condensation nuclei (CCN). CCN can be anything from dust particles to salt crystals.
The air must cool to its dew point. The dew point is the temperature at which the air is saturated with water vapor. When the air reaches its dew point, the water vapor will condense on CCN and form clouds.
In addition to these three conditions, there are other factors that can affect cloud formation, such as the wind and the amount of sunlight.

consider the forces on mass m₁ on the incline plane :
parallel to incline , force equation is given as
T - m₁ g Sin30 = m₁ a
T = m₁ g Sin30 + m₁ a eq-1
consider the force on mass m₂ on the incline plane :
m₂ g - T = m₂ a
T = m₂ g - m₂ a eq-2
Using eq-1 and eq-2
m₂ g - m₂ a = m₁ g Sin30 + m₁ a
inserting the values
(2.3 x 9.8) - 2.3 a = (3.7 x 9.8) Sin30 + 3.7 a
a = 0.74 m/s²
their speed, which is the speed of light
