Answer:
17.4 cm
Explanation:
Power of lens = +1.75 diopters
Focal length of lens

This is a convex lens as focal the diopter given is positive which makes the focal length positive. Image distance will be negative.
v = -25

∴ The new near point is 17.4 cm
Answer: A. by analyzing and making inferences about them
Explanation:
Answer:
Laser light however contains only one wavelength. This property makes lasers monochromatic, meaning of one color. Another property of lasers is that all the wavelengths are in phase, meaning they wave together. This property is called coherency. Laser light travels in the same direction, parallel to one another.

Answer:

Explanation:
The acceleration of a circular motion is given by

where
is the angular velocity and
is the radius.
Angular velocity is related to the period, T, by

Substitute into the previous formula.


This acceleration does not depend on the linear or angular displacement. Hence, the amount of rotation does not change it.
