From the gravity acceleration theorem due to a celestial body or planet, we have that the Force is given as

Where,
F = Strength
G = Universal acceleration constant
M = Mass of the planet
m = body mass
r = Distance between centers of gravity
The acceleration by gravity would be given under the relationship


Here the acceleration is independent of the mass of the body m. This is because the force itself depended on the mass of the object.
On the other hand, the acceleration of Newton's second law states that

Where the acceleration is inversely proportional to the mass but the Force does not depend explicitly on the mass of the object (Like the other case) and therefore the term of the mass must not necessarily be canceled but instead, considered.
Answer:
The net magnetic flux through any closed surface must always be zero.
Answer:
Momentum is define as the product of the mass and velocity of a body. It is measured in Kgm/s.
Explanation:
Momentum is the product of mass and velocity of an object. When an object or a body of mass 'm' is moving with velocity 'v', then its momentum can be determined as;
momentum (P) = mass × velocity
i.e P = m × v
= mv
It is measured in Kgm/s.
The change in momentum of a body is referred to as its impulse (Ft).
ΔP = m(v - u) = Ft
Where: P is the momentum of the object, m is its mass, v is its final velocity, u is the initial velocity, F is the force and t is the time in which the force acts.
The correct answer would be B.) 98°c-102°c
