If you lift the front wheel of a poorly maintained bicycle off the ground and then start spinning it at 0.72 rev/s, friction in the bearings causes the wheel to stop in just 12 s. The wheel has a mass of 3.33333 kg and a radius of 0.3 m. (a) What is the magnitude of the angular acceleration of the wheel as it comes to a stop

answer: the correct answer for the fill in the blank is rods.

rods are the specialized photoreceptor cells that are present in the retina of human eye. they are responsible for vision in the night time ( also called scotopic vision). they have very low visual acuity and color distinguishing ability.

as they are responsible for vision in night time, therefore they are found predominantly in the nocturnal animals.
