The gravitational force between the two objects A) It increases.
Explanation:
The gravitational force between two objects is given by:
(1)
where
G is the gravitational constant
are the masses of the two objects
r is the separation between the objects
In this problem, object A and object B are initially at a distance of
r = 100 m
And at that distance, the force between them is
F
Later, object A gains some mass. We notice from eq.(1) that the gravitational force is directly proportional to the mass: therefore, if the mass of either of the two objects increases, then the gravitational force between them also increases. Therefore, the new force will be larger than the original force:
F' > F

The molar latent enthalpy of boiling of iron at 3330 K is ΔH = 342 
10^3 J.
<u>Explanation:</u>
Molar enthalpy of fusion is the amount of energy needed to change one mole of a substance from the solid phase to the liquid phase at constant temperature and pressure.
d ln p = (ΔH / RT^2) dt
(1/p) dp = (ΔH / RT^2) dt
dp / dt = p (ΔH / RT^2) = 3.72 10^-3
(p) (ΔH) / (8.31) (3330)^2 = 3.72 10^-3
ΔH = 342 10^3 J.

Pressure is defined as Force applied in over an area such that it is perpendicular to it i.e.
Answer:
It acts in the direction opposite of motion.
Explanation:
The sliding friction is the one offering resistance to motion of the sliding cereal box.This force is created between the box and the tabletop that are sliding against each other.The sliding friction is proportional to the weight of the cereal box when pushed on the horizontal tabletop.We can apply the Newton's second law of motion to describe this motion, where force is a product of mass and acceleration.When the object is massive, the sliding friction force experienced is high thus sliding happens slowly.
at first there is 10 electron in neon . 2 electron present at k shell and 8 present l shell . there is no rules of atomic structure . becomes it being wrong.
