we are given
A cd has diameter of 120 millimeters
so, d=120mm
so, firstly, we will find radius
we can plug it
we know that
1mm=0.001m
so, we get
the angular speed is about 206 rpm
we know that
1 revolution =2pi radians
so, we get
now, we can change it into seconds
1 min =60 seconds
so, we get
now, we can find linear speed(v)
we can use formula
v=w*r
so, we can plug values
and we get
so, linear speed is 1.257 m/sec............Answer

Step-by-step explanation:
everything is directly proportional, so your are going to do cross muliplication
y= -24/7
Answer:
In order of the blanks from left to right, 30; 6; 2; 1/2; 20; 12; 12; 3/5
Step-by-step explanation:
So the rectangle has an area of 60 inches squared & the equation for the area of a rectangle is width * height. So, you can find the missing term if you just take 60 & divide it by the given number.
60/2 = 30
60/10 = 6
60/30 = 2
60/120 = 1/2
60/3 = 20
60/5 = 12
60/5 = 12
60/100 = 3/5
