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°
