Question
Chapter 25, Problem 6Q
To determine
If the person in the figure is farsighted or nearsighted.
Expert Solution & Answer
Answer to Problem 6Q
Solution:
The person is nearsighted.
Explanation of Solution
In the figure person’s face is seen narrow through the glasses.
And it is given that one can identify whether people are farsighted or nearsighted by looking at the width of their face seen through their glasses.
The person in the figure is nearsighted.
For correcting nearsightedness diverging lenses are used, and for correcting farsightedness converging lenses are used.
In the figure, person’s face is seen narrow through the glasses. If a person’s face is seen narrower through the glasses, then the image of the face produced by the lenses is smaller than the face, virtual, and upright, which means the lenses must be diverging type. Since diverging lens are used for correcting nearsightedness, the person is nearsighted.

- Shrinking Loop. A circular loop of flexible iron wire has an initial circumference of 161 cm , but its circumference is decreasing at a constant rate of 15.0 cm/s due to a tangential pull on the wire. The loop is in a constant uniform magnetic field of magnitude 1.00 T , which is oriented perpendicular to the plane of the loop. Assume that you are facing the loop and that the magnetic field points into the loop. Find the magnitude of the emf E induced in the loop after exactly time 9.00 s has passed since the circumference of the loop started to decrease. please show all stepsarrow_forwardAromatic molecules like those in perfume have a diffusion coefficient in air of approximately 2×10−5m2/s2×10−5m2/s.
