A radial saw has a blade with a 6-in radius.
1 answer:
Answer:
The angular speed of the blade is of 166.67 rad/min
Step-by-step explanation:
The velocity, is given by the following equation:
In which r is the radius and w is the angular speed.
We use this relation to solve this question;
We have that:
. We want to find w. So
The angular speed of the blade is of 166.67 rad/min

You haven't provided the expression or the choices, therefore, I cannot provide an exact answer.
However, I'll try to help you understand the concept so that you can solve the question you have
Like radicals are characterized by the following:
1- They both have the same root number (square root, cubic root , ...etc)
2- They both have the same radicand (meaning that the expression under the root is the same in both radicals)
Examples of like radicals:

and 7
![\sqrt[5]{x^2y}](https://tex.z-dn.net/?f=%20%5Csqrt%5B5%5D%7Bx%5E2y%7D%20)
and 3
Check the choices you have. The one that satisfies the above two conditions would be your correct choice
Hope this helps :)
