Which two phenomena are evidence that gravitational forces are attractive? Select two statements. A. the rise and fall of the tides
B. atoms being held together in a molecule
C. a dropped object always falls toward Earth
D. microwaves passing through the atmosphere into space

A. the rise and fall of the tides.

C. a dropped object always falls toward Earth.

Explanation:

Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.

Additionally, the gravity of earth makes it possible for all physical objects to possess weight.

The two phenomena which are evidence that gravitational forces are attractive includes;

I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.

II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.
