Answer:
Gravity
Explanation:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all
F=(Gm1m2)/r^2
ratio = (1/6370^2) / (1/7770^2) = 1.48786378457
10 – 3 + 8 = 15 meters
10 + 3 + 8 = 21 meters
Her total traveled is 21 meters, displacement is 15 meters.
Answer:
Moving up one step from there, a camera with a single element lens has a convex lens. It may be a meniscus lens which is convex on one side and concave on the other, but it is thicker in the middle than the edges and functions like a convex lens. (The meniscus shape helps the lens focus light on a flat focal plane.)
