(a)

To determine

To estimate: The angle of rotation in the photo.

(a)

Expert Solution
Check Mark

Answer to Problem 21PPS

The angle of rotation in the photo is 10° .

Explanation of Solution

No of spokes in the wheel is 36 .

The angle subtended by each spoke is,

  Angleeach=360°36=10°

Therefore, the angle of rotation of the photo is 10° .

Answer to Problem 21PPS

The shutter speed of camera is 1.7 seconds.

Explanation of Solution

No of spokes in the wheel is 36 .

The shutter speed is calculated as,

  vshutter=6036=1.7 sec

Therefore, the shutter speed of camera is 1.7 seconds.
