It is important to wear protective equipments during games and practices.
Explanation:
Practice is a review of what is about to happen in some time to come and with practice ,the future can be trusted.
During practice it is very important to use protective gears or equipments because without them, injuries and accidents are liable to occur.
During the major game it is also important to prevent accidents or big injuries as the equipments protect each vital part of the body.
Answer:
angular speed of both the children will be same
Explanation:
Rate of revolution of the merry go round is given as
f = 4.04 rev/min
so here we have
![f = \frac{4.04}{60} =0.067 rev/s](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7B4.04%7D%7B60%7D%20%3D0.067%20rev%2Fs)
here we know that angular frequency is given as
![\omega = 2\pi f](https://tex.z-dn.net/?f=%5Comega%20%3D%202%5Cpi%20f)
![\omega = 2\pi(0.067)](https://tex.z-dn.net/?f=%5Comega%20%3D%202%5Cpi%280.067%29)
![\omega = 0.42 rad/s](https://tex.z-dn.net/?f=%5Comega%20%3D%200.42%20rad%2Fs)
now this is the angular speed of the disc and this speed will remain same for all points lying on the disc
Angular speed do not depends on the distance from the center but it will be same for all positions of the disc
