question 55

Multiple Choice

The drive chain in a bicycle is applying a torque of $0.850 \mathrm {~N} \cdot \mathrm { m }$ to the wheel of the bicycle. You can treat the wheel as a thin uniform hoop (or ring) with a mass of 0.750 kg and a radius of 33.0 cm. What is the angular acceleration of the wheel?

• A) \(20.8 \mathrm { rad } / \mathrm { s } 2\)
• B) \(5.20 \mathrm { rad } / \mathrm { s } ^ { 2 }\)
• C) \(10.4 \mathrm { rad } / \mathrm { s } ^ { 2 }\)
• D) \(3.43 \mathrm { rad } / \mathrm { s } ^ { 2 }\)
• E) \(1.06 \mathrm { rad } / \mathrm { s } ^ { 2 }\)

Definitions:

Retina

A thin layer of tissue at the back of the eye that contains cells sensitive to light, which trigger nerve impulses that pass via the optic nerve to the brain.

Upside-Down Image

Refers to the way images are projected onto the retina in the eye, which the brain then interprets and flips to the correct orientation.

Retina

The light-sensitive layer of tissue at the back of the inner eye that converts light images into nerve signals sent to the brain.

Optic Disks

The point in the eye where the optic nerve connects to the retina, lacking photoreceptors, and creating a blind spot.
