Please help quick A whale shark has a mass of 2.04 x104 kg and a blue whale has a mass of 1.81 x105kg. If the two whales are 1.5 m apart, what is the gravitational force between them?

If an asteroid with a mass of 1.4 x1021kg were to orbit at the same distance the Moon is from the Earth, what would be the gravitational force between the Earth and the asteroid? The mass of the Earth is 5.98 x1024kg and the distance to the Moon is 3.84 x108m

A comet moves with a velocity of 2.5 x104m/s through Space. The mass of the star is 3 x1030 kg . How far from the star is the comet orbiting?

A satellite rotates around the Earth once every day. The mass of the Earth is 5.98 x1024 kg. What is the orbital speed of the satellite? (Hint: the period is 1 day, but you need the time in seconds, not days)

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

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.
