The gravitational force between Earth and the Sun is a two-way force. Both the planet and the Sun attract each other. However, E
arth revolves around the Sun rather than the Sun revolving around Earth. Which statement BEST explains the orbit of the Earth around the Sun? A) The Sun is at the center of the Solar System.
B) The Sun’s mass is much greater than Earth’s.
C) Earth rotates about its axis, but the Sun does not.
D) Other planets also try to move the Sun around them

Sound waves need different media in order to travel. This travels by the movement of the atom transferred to another up to its destination. The speed of sound is greatest in solids since the molecules of solid are closely packed together, followed by liquid and they are slowest in gases.
