Roshan makes the table below to describe how to draw a ray diagram for a convex lens.
what error did roshan make?
the ray that goes through the center should bend and go through the focal point on the other side.
the ray that starts out parallel with the main axis should bend toward the axis and go through the focal point on the other side.
the ray that goes parallel to the main axis after passing through the lens should also be parallel from the object to the lens.
the rays in the table describe how rays are drawn for a concave lens rather than for a convex lens.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

the answer would be   dignified - apex

the force on the thing and the distance the force moves the thing
