A barracuda started swimming at a constant velocity of 3.5 meters per second toward a coral reef
exactly 15 seconds after the sun rose. At this velocity, how long did it take the barracuda to travel
9.1 meters toward the reef?
Write your answer to the tenths place.
seconds

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
