PLS ANSWER I WILL GIVE BRAINLIEST AND 75 POINTS As an airplane rises through the atmosphere, machines cause the pressure inside the cabin to decrease. Based on your observations from the Can Crush Lab, why is this change in pressure necessary?

Air pressure inside the plane should match the air pressure outside the plane.
Air pressure inside the plane should be less than the air pressure outside the plane.
Air pressure outside the plane should be less than the air pressure inside the plane.
Air pressure outside the plane should be more than the air pressure inside the plane.

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.
