The ball will bounce at a height lower than the height it was dropped.
Answer: Option B.
<u>Explanation:</u>
When a basket ball is thrown from a particular height, it bounces back. But the height it bounces back at is not exactly the same height from where it was thrown.
With further bounces, the energy of the basket ball goes on decreasing and the bounces go on getting smaller. This shows that there is a change in the energy of the basket ball with every bounce that the ball makes. Some energy lost from the ball gets absorbed by the court and some of the energy is changed into thermal energy.
Explanation:
It is known that like charges tend to repel each other whereas unlike charges tend to attract each other. This means that two positive charges when come closer to each other will repel each other and if a negative charge comes in contact with a positive charge then both of them will attract each other.
Therefore, when you charge a pocket comb by rubbing it with a silk scarf then the scarf will obtain a certain charge. But as we place this silk scarf closer to the comb then if the scarf gets attracted towards the comb then it means opposite charges are present on both comb and the scarf.
But if the scarf and comb repel each other then it means opposite charges are present on them.
Both balls hit the ground at the same time.
We've known this fact for about 500 years (since Galileo),
and we've known WHY for about 300 years (since Newton).
