Because he left the clear acrylic balls in the sun for a long time so they could have melted a bit so that would be why you got mad at him
Answer:

Explanation:
Since the two charged bodies are symmetric, we can calculate the electric field taking both of them as point charges.
This can be easily seen if we use Gauss's law, 
We take a larger sphere of radius, say r, as the Gaussian surface. Then the electric field due to the charged sphere at a distance r from it's center is given by,

which is the same as that of a point charge.
In our problem the charges being of opposite signs, the electric field will add up. Therefore,

where,
= distance between the center of one sphere to the midpoint (between the 2 spheres)
Answer:
4400 N
Explanation: (c)
P= 
F= PA
P= pressure
A= area
P=800x
and A= 5.5 x 

Force F= 800x
x0.0055= 4400 N
force exerted by the gas on the piston is 4400 N
If the field strength between the plates is 9 volts per cm, then over a path of 1/2cm parallel to the field, the potential changes by (1/2) x (9 volts) = 4.5 volts.
