On the earth when we throw something up, it comes down because,

Options

A. Earth pulls every object towards itself.
B. Earth pushes away everything.
C. Earth is flat.
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why an object thrown upwards on Earth eventually comes back down.

2. **Initial Force**: When we throw an object upwards, we apply a force that gives the object an initial velocity in the upward direction.

3. **Effect of Gravity**: As the object moves upward, the force of gravity acts on it. Gravity is a force that pulls objects towards the center of the Earth.

4. **Decrease in Velocity**: As the object rises, the upward force we applied decreases due to the pull of gravity. Eventually, the upward velocity of the object decreases until it reaches zero at its highest point.

5. **Change in Direction**: Once the object reaches its highest point (where its velocity is 0), the gravitational force continues to act on it, pulling it back down towards the Earth.

6. **Conclusion**: Therefore, the reason the object comes back down is that the Earth pulls every object towards itself due to the gravitational force.

7. **Correct Option**: The correct answer to the question is that "Earth's pull every object towards itself."
