Digital bits on a 12.0-cm diameter audio cd are encoded along an outward spiraling path that starts at radius r1=2.5cm and finishes at radius r2=5.8cm. the distance between the centers of neighboring spiral-windings is 1.6μm(=1.6×10−6m). part a determine the total length of the spiraling path. [hint: imagine "unwinding" the spiral into a straight path of width 1.6μm, and note that the original spiral and the straight path both occupy the same area.]

total length of the spiral is L is  5378.01 m

Explanation:

Given data:

Inner radius R1=2.5 cm

and outer radius R2= 5.8 cm.

the width of spiral winding  is (d) =1.6 \mu m =  1.6x 10^{-6} m

the total length of the spiral is L is given as

= 5378.01 m

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
