Answer:
5833.33
Explanation:
= Angular acceleration
= Number of revolutions
= Initial angular speed = 0
t = Time taken = 2 s
Final angular speed
From the equation of rotational motion we have
The number of revolutions is 5833.33
<span>The answer is simply that evolution takes a long time to make big changes. To see evidence of that, you have to look at older records. You have to look at fossils.</span>
Put your bet down on Choice 'A'. The others are just flat wrong.
Answer:
a baseball flying through the air at 90 miles per hour
Explanation:
For the question, Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If the velocity is doubled the kinetic energy will increase by a factor of four.
