Air pressure is lower at high altitudes. an airplane cabin can adjust, but as the plane rises, passengers can experience temporary pain in their ears. check all facts below that explain why. the air pressure in the ears increases. the air pressure in the ears decreases. the volume of air in the ears increases. the volume of air in the ears decreases. the change in volume causes discomfort. it takes time for the ears to dispell excess air past the ear drum.

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
