Light incident on a glass sheet is partly reflected and partly refracted. how is the reflected ray different from the refracted ray?

the refracted ray is unpolarized whereas the reflected ray is horizontally polarized.

the refracted ray is unpolarized whereas the reflected ray is vertically polarized.

the refracted ray is horizontally polarized whereas the reflected ray is
unpolarized.

the refracted ray is vertically polarized whereas the reflected ray is unpolarized.

the refracted ray is vertically polarized whereas the reflected ray is horizontally polarized.

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s. assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
