Determine the values of mm and nn when the following mass of the earth is written in scientific notation: 5,970,000,000,000,000,000,000,000 kgkg. enter mm and nn, separated by commas.

Mass of the Earth,

Explanation:

The mass of the Earth is equal to :

m = 5,970,000,000,000,000,000,000,000 kg

We need to write the mass of the Earth in the form of scientific notation. Any number is written in the form of scientific notation as :

a is any real number

b is any integer

There are 22 zeroes in the mass of Earth. In scientific notation mass of the Earth is given by :

Hence, this is the required solution.                

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.
