1)The P ray is directed parallel to the axis of the lens. It emerges from the lens directed toward the focal point on the side of the lens opposite the object.
2) The M ray is directed toward the midpoint of the lens. It emerges from the lens unchanged in direction.
3) The F ray is directed toward the focal point on the same side of the lens as the object. It emerges from the lens directed parallel to the lens axis.
The answer is C. The ball and floor had friction between them causing the ball to stop rolling
Answer:
I believe the bowling ball would be the correct answer.
Explanation:
(1×10^-5)/(1.6×10^-19)= 6.25×10^13 electrons(ans)
Notice that the charge of a sphere is very larger than charge of electron obviously, so each electron on the sphere is made of 1.6×10^-19 charge, so you found how many of these charges are required for you to make a charge of 1×10^-5
for Example: your electron has charge 2 on it
and the sphere has charge 200 on it, then the number of electrons that make up that charge will be
200/2 = 100 electrons.
