The variable typically used to denote charges is q
and the unit of charge is given by:
1 coulomb = 1C
Electrostatics is the study of the interaction of
electric charges in static equilibrium. An electric

Substance are composed of molecules, the total mass is the sum of the individual masses of all the molecules. Mass does not
change with position, nor is i
Simple stresses are expressed as the ratio of the applied force divided by the resisting

It is the expression of force per unit area to structural members that are subjected to
external forces and/or induced forces

A frequency distribution is a collection of observations produced by sorting them
into classes and showing their frequency (or numbers) of occurrences in each class.

Is this the expected result? Explain.
Yes, it must be equal if the light sources intensities are equally transmitted to the
photometer. However, in the actu

If the two light sources have the same intensity, their distances from the photometer are
the same. If we set the t
