Answer:
By a factor of 9/4
Explanation:
Applying Coulomb's law,
F = kqq'/r²................... Equation 1
Assuming q and q' are the two point charges respectively.
Where k = coulomb's constant, r = distance between the charges.
When the point charges are 3.0 m apart,
F = kqq'/3²
F = kqq'/9.................... Equation 1
When they are moved to a new distance, 2.00 m
F' = kqq'/2²
F' = kqq'/4................. Equation 2.
Comparing equation 1 and equation 2.
F' = 9F/4
Hence the resulting mutual force change by a factor of 9/4
We wait a little after changing the volume of the trapped gas, to make sure that is the gas is back to room temperature.
<h3>
Boyle's law</h3>
This law states that the volume of a fixed mass of a gas is inversely proportional to its pressure provided that temperature remains constant.
P₁V₁ = P₂V₂
<h3>Why we wait a little </h3>
We wait a little after changing the volume of the trapped gas, to make sure that is the gas is back to room temperature because a change in temperature can alter the accuracy of the experiment.

The statement is <em>TRUE</em>.
"Displacement" means the distance and direction from the start-point to the end-point, NO MATTER how you got there.
If you go out cycling and go back home when you're done, your displacement is zero. it doesn't matter how far you cycled, or what streets or woods you cycled through, or whether your route was a circle, a square, an ellipse, a triangle, or a jumble, or whether you cycled around and around the same path 27 times. You ended right where you started. The distance from your start-point to your end-point is zero, so your displacement is zero.
<span>The same atomic number. The periodic table assembles all of the recognized elements appropriate increasing atomic number. Order usually accords with increasing atomic mass. The number of electrons in a period rises as one it moves down the periodic table; so, as the energy level of the atom rises, the number of energy sub-levels per energy level rises.</span>
