If light travels from oil (slower medium) to water (faster medium) at an angle, what happens to the direction of the light ray in water with respect to normal?
a. it moves away from the normal. b. it moves toward the normal.
c. it will move along the normal. d. it will move perpendicular to the normal.
e. it stops traveling.

If light travels from oil to water at an angle, what happens to the direction of the light ray in water with respect to the normal, is it moves away from the normal.

to shorten the other answer...its A

Explanation:

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
