Two identical satellites orbit the earth in stable orbits. one satellite orbits with a speed v at a distance r from the center of the earth. the second satellite travels at a speed that is less than v. at what distance from the center of the earth does the second satellite orbit?

The second satellite will orbit at a larger distance

Explanation:

A satellite orbits the Earth due to its gravitational attraction to the Earth, which is equal to the centripetal force, so we can write

where

G is the gravitational constant

M is the Earth's mass

m is the satellite's mass

r is the distance of the satellite from Earth's center

v is the speed of the satellite

We can rewrite the formula as

so we see that the distance of the satellite from the center of the Earth is inversely proportional to the square of the distance. This means that the second satellite, which travels at a lower speed, will have a larger distance from the centre of the Earth.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
