This is true!!
Good luck hope this helped!
Answer:
7.69km/hr due east
Explanation:
Given parameters:
Displacement due west = 3km
Displacement due east = 2km
Time taken = 8 minutes
Unknown:
Average velocity = ?
Solution:
Average velocity is the rate of change of displacement with time.
Velocity = 
Displacement is deals with the start and the end;
Here, displacement = 3km - 2km = 1km due east
Time = 8min
60min = 1hr
8min = 
= 0.13hr
Average velocity = 
= 7.69km/hr due east
<span>Answer: Doppler radar
Doppler radar or weather radar is used to locate precipitation,</span> forecast future intensity, calculate
or detecting its motion and estimates precipitation whether it is a rain, snow,
hail or storm. They are also helpful in determining the structure of storms and
its potential to cause severe weather.
Moreover, if a portion of the atmosphere becomes
saturated with water vapor, it will condense and precipitate allowing Doppler
radar to analyze and observe precipitation.
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.
