A light source O is placed in front of a plane mirror as shown in

the figure. O' is a point on the path of

the reflected ray. What is the distance of

the point on the mirror from where

the light gets reflected (measured

from point A)?

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.
