Answer: The given statement is True.
Clouds are formed due to condensation of water vapors. Condensation can be described as a process of change of gaseous form of water (that is water vapor) into liquid form.
When sunlight strikes various aquatic bodies, water is heated up and it rises high in the atmosphere in the form of water vapors.
When these vapors meet a lower temperature in the atmosphere, they cool and the air loses its capacity to hold them.
Due to this, vapors condense and form clouds.
Thus, given statement is True.
Answer:
By definition, air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the oncoming flow velocity, thus slowing the object down.
Explanation:
Answer:
Option "D" is the correct answer to the following question.
Explanation:
According to The law of conservation of mass, in a chemical reaction mass neither created nor destroyed.
So,
Total product = Mass of magnesium + Mass of oxygen
Total product = 40 gram + 40 gram
Total product = 80 gram
Therefore, option "D" is the correct answer
in cgs system, plank's constant= h=6.626 x10⁻²⁶ erg s
Value of Plank's constant in SI system= 6.626 x10⁻³⁴ Js
now 1 Joule= 10⁷ ergs
so h= 6.626 x10⁻³⁴ Js (10⁷ ergs/1J)
h=6.626 x10⁻²⁷ erg s
