The picture above shows the Apollo spacecraft that took astronauts to the Moon in 1969. The spacecraft weighed 6.1 million pounds, and its motors produced 7.5 million pounds of thrust. How did the spacecraft leave the surface of Earth?

A) The spacecraft produced an upward force of thrust that was equal to the downward force of gravity.

B) The spacecraft produced an upward force of thrust that was greater than the downward force of gravity.

C) The spacecraft produced a downward force of thrust that was equal to the downward force of gravity.

D) The spacecraft produced a downward force of thrust that was less than the downward force of gravity.

33: i think it’s b

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 is the best answer your welcome
