A 2.0-cm-tall object is 17 cm in front of a diverging lens that has a -30 cm focal length. Calculate the image position.

Express your answer to two significant figures and include the appropriate units. Enter positive value if the image is on the other side from the lens and negative value if the image is on the same side.

Calculate the image height.

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.

a and b sometimes have a positive value
