The speed of light in air is 3.0 x 108m/s. The speed of light in a transparent liquid is 2.0 x 108m/s.
A ray of light is incident on the surface of the liquid at an angle of incidence of 40°.
Calculate

(i) the refractive index of the liquid,

refractive index =

What conclusion can be made based on the temperature of soil when the light hits the soil at 0°, 45°, and 90° angles in section 2 of the experiment? did your results support your hypothesis? why or why not?

What is the measure of how much matter is in an object and that can be measured using a balance? a. height b. volume c. weight d. mass

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
