Suppose a CAV player makes 48 revolutions per minute. Through how many degrees will a point on the edge of a CD move in 1 minute? In 2 sec?

• Chemistry -

Each revolution moves through 360 degrees.

So 48 RPM moves through 48*360° in one minute.

In two seconds, the angle is
48*360*(2/60)
=48*12
=576°
