Explanation:
a. Mechanical advantage = force out / force in
MA = 830 / 100
MA = 8.3
b. Efficiency = work out / work in
0.80 = W / 600 J
W = 480 J
We do not feel the gravitational forces from objects other than the Earth because they are weak.
Yes, Older volcanoes eventually turn into islands and seamounts.
