Answer:
the similarity is that hands are applied and force
Answer:
2.5 m/s
Explanation:
you have to subtract 5 meters because you start at 5 meters. so Just take (30m-5m)/10s=2.5m/s
Answer: Two children are riding on a marry-go-round. Child A is at a greater distance from the axis of rotation than child B. Thus, the child A, located at a greater distance from the axis of rotation have a larger tangential speed.
Explanation: To find the correct answer we have to know more about the Angular velocity of a rotating body.
<h3>What is the angular velocity?</h3>
- In rotational motion, the angular velocity ω can be defined as, the change in angular displacement(Ф) per unit time (t).
- It's the revolution per second.
- The angular velocity can be expressed in terms of the tangential velocity as well as the radius of the circular path as,
<h3>
How to solve the question?</h3>
- We know that the expression for the tangential velocity as,
- In the question, for both the child, the value of w will be same. Thus, the only quantity that depends on the tangential velocity will be the distance from the axis of rotation.
- The maximum will the value of V, if the r maximizes.
- Thus, child A with greater distance will have larger tangential speed.
Thus, we can conclude that, child A with greater distance will have larger tangential speed.

Answer:
$531
Explanation:
If the first three months are free, take off 3 from 12. That leaves you with 9. Since you pay $59 every month, 59 x 9 is 531
Upon discovering so, this helps to confirm the theory of evolution
