2. How much stronger will the force between two charges be if the distance between them
is cut in half? If the original force was 50N,
what will the new force be?

Acurve connects the data points that are plotted. (physical science chapter 11 motion)

Avalue that describes how heavy an object is and is related to the force of gravity is

Arod of some material 0.20 m long elongates 0.20 mm on heating from 21 to 120°c. determine the value of the linear coefficient of thermal expansion [in (degrees c)^-1] for this material.
