Suppose the circumference of a bicycle wheel is 2 meters. if it rotates at 1 revolution per second when you are riding the bicycle, then your speed will be: a) 3.14 m/s. b) 1 m/s. c) 2 m/s. d) 3 m/s. e) 6.28 m/s.

(c) speed will be 2 m/sec

Explanation:

We have given circumference C = 2 meters

Angular velocity = 1 rev/sec =1×2π rad/sec

We know that circumference , where r is the radius of circumference

So

r = 0.318 meter

Linear velocity

So option C will be the correct option

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
