Decreasing the separation between the two magnets will result in increase in the magnetic force between two magnets.
<h3>What is a Magnet?</h3>
This is referred to a substance which produces magnetic field and result in the attraction and repulsion of certain types of things.
Increase in the separation will reduce the magnetic force and vice versa which is why option A was chosen.

In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of
fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
Hope this helped.
The molecular formula of a compound having the empirical formula C9H17O is calculated as below
(C9H17O)n =847.56
{(12 x9 + 1 x17 + 1 x16)}n= 847.56
147 n = 847.56
divide bot
h side by 147
n= 6
(C9H17O)6 therefore the molecular formula = C54H102O6
Answer: .309 moles (rounded to the nearest thousandth)
