Avery massive object a and a less massive object b move toward each other under the influence of gravity. which force, if either, is greater

Both are equal.

Explanation:

As per the theory of gravitational force, when two objects will be thrown from same height but of different masses, both will reach the ground at same time.

The force of gravity will act same on both objects.

Simple experiments were done by Sir Isaac Newton to reach out to reach out to this conclusion. Two objects were made to fall free under the influence of gravity, neglecting every other small forces, it was observed irrespective of different masses both reaches the ground at same time.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered
