Where should an object be placed in front of a concave mirror’s principal axis to form an image that is real, inverted, larger than the object, and farther from the mirror than the object is?

At focus.

Explanation:

When the object is placed at the focus of a concave mirror, the image will form at infinity. The formed image is real and inverted and its size is highly enlarged.

When the object is placed between the pole and the focus, the image will formed behind the mirror. The formed image is virtual and erect and its size is enlarged. This is the only case when the formed image is virtual and erect.

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.
