A Titan IV rocket has put your spacecraft in a circular orbit around Earth at an altitude of 280 km. Calculate the force due to gravitational attraction between the Earth and the spacecraft in N if the mass of the spacecraft is 2550 kg.

Explanation:

The force experimented by the rocket due to the gravitational attraction is given by the following formula:

Where and are the masses of the rocket and Earth, respectively.

The force due to the gravitational attraction is:

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.
