Number 1 is:
C and E
Number 2 is:
400
The angular velocity for this problem is given by:
Angular speed = 200 rev / min
The first thing you should keep in mind is the following conversion:
1 rev = 2π radians
Applying the conversion we have:
Angular speed = 200 * (2π)
Rewriting:
Angular speed = 200 * (2 * 3.14)
Angular speed = 1256 radians / minutes
Answer:
the angular speed is:
Angular speed = 1256 radians / minutes
What is the underlined word ??
Answer:
9 more weeks
Explanation:
She already saved 20(3)=60
240=60+20(x)
X=9
