When it is moving to the left. the sign of the velocity specifies the direction of the object/ particle
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.
The electromagnetic waves do not need any medium to travel as they are not mechanical in nature. They propagate in the form of electric and magnetic energy having a perpendicular vector of its velocity wave
Answer:
Newtons (N)
Explanation:
Because the people in charge of defining SI units said so
