Unlike record players which rotate at a constant angular velocity, the CD-ROM driver in a CD player rotates the CD at different
zimovet [89]

Answer:

A. 21 rad/s

B. 200.5 rpm

C. 26.46 rad/s2

D. 0.299 Hz

Explanation:

Parameters given are:

Tangential velocity,v = 1.26m/s

Diameter (outer edge) = 0.120m

Outer edge radius, ro = 0.12/2

= 0.06m

A. Calculate Angular velocity

Angular velocity, w = v/r

= v/ro

= 1.26/0.06 = 21 rad/s

In rpm,

2pi/60 rad/s = 1 rpm

1 rad/s = 60/2pi rpm

Sp, 21 rad/s = 60 * 21/2pi rpm

= 200.5 rpm

B. Calculate the inner edge radius, ri given w = 500 rpm

Converting rpm to rad/s,

= 2pi/60 * 500 rad/s

= 52.34 rad/s

ri = v/w

= 1.26/ 52.36

= 0.024m

C. Calculating centripetal acceleration, a from the outer edge, ro

a = v2/r = w2r

= (1.26)2/0.06

= 26.46 rad/s

D. Calculate the frequency, f of the outer edge angular velocity, w = 21 rad/s

f = 2pi/w

= 2pi/21

= 0.299 Hz (or per second)

Which activity is the best demonstration of j.j. Thomsons use of creativity in his work?
ch4aika [34]

<span>The activity which is the best demonstration of Joseph John  Thomson's use of creativity in his work when he devised a better method and equipment in studying cathode rays. This activity led to the discovery of originally termed particles “corpuscles” which are now known as “elections”. This discovery also upended the dominating theory that atoms are the smallest fundamental unit.
