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.

Here we have to choose the partial pressure exerted by the air in the given sample among the given options.
The partial pressure of the air in the sample is C. 96.82 kPa.
As per the Dalton's law of partial pressure the total pressure of the gas in the pool (P) is equivalent to the summation of the partial pressure of water vapor and air pressure.
Mathematically we may write:
Now the 
Or, P_{Air}[/tex] = (100.18 - 3.36) kilopascals
Or, P_{Air}[/tex] = 96.82 Kilopascals.
Thus the partial pressure of the air in the sample is C. 96.82 kPa.
Answer:
3.95 x 10³ s⁻¹.
Explanation:
∵ The value of the half-life is independent of the initial concentration of the reactant present.
∴ The reaction is a first order reaction.
- <em>The relation between half-life (t1/2) and rate constant for the first order reaction is: (t1/2) = ln2/k = 0.693/k.</em>
∴ k = ln2 / (t1/2) = 0.693 / (1.751 x 10⁻⁴ s) = 3.95 x 10³ s⁻¹.

Answer:
Which elements have a larger atomic radius?
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
