Lets say sphere 1 has a charge of 12 + and sphere 2 has a charge of 0 +. After they are touched Sphere 1 becomes 6 + and sphere 2 6 +. So 6 - 12 = a change of 6 -, while 6 - 0 = a change of 6 + Therfore,
Answer: The sign of the charge change / transfered are opposites.
The net charge of the electron will be there because there is no exponents there
Answer:

Explanation:
Given




Required
Determine the linear equation for P in terms of h
First, we calculate the slope/rate (m);
The following formula is used:

Substitute values for P's and h's



Multiply by 1000/1000


The equation is then calculated using:

Substitute values for m, h1 and P1



Make P the subject

<em>The above is the required linear equation</em>
