A very massive body A and a less massive body B move toward each other under the influence of gravity. Compared to the force on A, the force on B is
1) greater.
2) the same.
3) less.
As A and B get closer and closer, each experiences an increase in
4) velocity.
5) acceleration.
6) force.
7) all of these.
8) none of these.
Question 2
In the hydraulic device shown, when the small piston is pushed down 10 cm with a force of 10 N, the large piston is raised 1 cm. This means that the large piston is capable of lifting
1) 10 N,
2) 100 N,
3) 1000 N,
4) any amount of weight,
which illustrates
5) that impulse is equal to a change in momentum.
6) (F d) input = (F d) output.
7) Newton's second law.
8) that the stored energy that a body possesses may be transformed into other forms of energy.
Abiotic factors influence population densities.
