Answer 2

Force of gravity is responsible for (D) Both revolution of planets and tides.

About Force of gravity:

• A body is drawn toward the center of the earth or any other mass-containing physical body by the force of gravity.
• Of the four recognized fundamental forces of physics, gravity is the weakest but also the most powerful.
• Gravity keeps the entire solar system and galaxy together, despite being the weakest force.
• Over the whole surface of the earth, free fall occurs at a constant speed.
• This implies that everything falls at the same speed.
• On Earth, its speed is estimated to be 9.8 m/s.

Revolution of planets:

• The planets orbit the sun due to inertia and the gravitational pull of the sun.
• All objects in space are subject to the law of inertia.
• For instance, the inertia of the moon and the gravitational pull of the Earth cause the moon to orbit the Earth.

Tides:

• Ocean waves called tides to go great distances.
• They result from the earth's gravitational pull from the moon and, to a lesser extent, the sun.
• A shore experiences a high tide when the wave's highest point, or the crest, reaches it.
