the correct answer is D- Acceleration depends indirectly on the mass.
According to Newton's second law, the force F, the mass m and the acceleration a are related as follows:

Therefore,

The acceleration <em>a₁ </em>of the mass<em> m₁ =1 kg</em> is given by,

The acceleration <em>a₂ </em>of the mass <em>m₂=10 kg</em> is given by,

The smaller mass has greater acceleration.
Thus, when the force applied on two bodies of different masses remains constant, then,

Acceleration is inversely proportional to the mass of the body.
The answer is B) Sleep disorder. Notice that is says, "A condition that affects the ability to sleep or quaility of sleep." Meaning how much sleep you get. Also known as sleep disorder. Answer is B. Hope that helps :)
Answer: Moon is much smaller in size and has very less mass, when compared to our mighty earth and there is absence of strong magnetic field on the moon which could protect from the incoming solar radiation from the sun. Since there is no magnetic field, it can swipe off any materials that are present there on the moon, diminishing the atmosphere.
This is the reason why moon does not have any atmosphere.
