Answer:
First option, check image uploaded.
Explanation:
Acceleration defined as time rate of change of velocity. Or change in velocity per change in time.
Acceleration is also the slope of the graph of velocity against time.
Also change in displacement with time is velocity.
From the given options, the correct graph is in the first option, as shown in the image uploaded.
Roughly 4 minutes less than 24 hours.
Answer: 14.28 m/s
Explanation:
Assuming the girl is spinning with <u>uniform circular motion</u>, her centripetal acceleration is given by the following equation:
(1)
Where:
is the <u>centripetal acceleration</u>
is the<u> tangential speed</u>
is the <u>radius</u> of the circle
Isolating from (1):
(2)
<u />
Finally:
This is the girl's tangential speed
Answer:
See below.
Explanation:
The difference between these two is that a wave is a disturbance of some quantity in space or intermediate while a particle has a definite mass concentrated on a small area.
