To choose:The correct option.
Answer to Problem 26R
The correct option is C.
Explanation of Solution
Introduction:
Mirrors are those curved surfaces which are polished at one side and light rays’ incident on it disperse or converge by the phenomena of reflection. A lens is made of transparent plastic or glass which can have convex surface or concave surface. This is an optical device which focus or disperse the light by the phenomenon of refraction.
Consider the reflection diagram shown below.
The light rays originating from the bulb, after reflecting go to parallel to the principle axis, which is the property of a concave mirror.Therefore, the mirror used is concave mirror.
Conclusion:
Thus, the correct option is C.

The box/belt friction coefficient is 0.15. For what duration will the box slide on the belt? In which direction does the friction force act on the box? How far will the box have moved horizontally by the time it stops sliding along the belt?arrow_forward

The proton is positively charged, the electron negatively, but both with the same magnitude of charge given by e=1.602x10-19C. The mass of an electron is 9.11x10-31kg, and the proton is 1.67x10-27kg. Find the ratio of the electrostatic to the gravitational force of attraction between the electron and the proton in hydrogen. \arrow_forward
