Question

скорость искуственного спутника Земли 8 км в час а пули винтовки 800 км в час сравните эти скорости

Answer 1

опечатка - не 8 км/ч, а 8 км/с 

8 км/с = 8*3600 = 28800 км/ч

Answer 2

Comparing Speeds of Earth's Artificial Satellite and Rifle Bullets

The speed of Earth's artificial satellite is approximately 8 km/h, while the speed of rifle bullets is around 800 km/h. Let's compare these speeds.

The speed of Earth's artificial satellite is relatively slow, at 8 km/h. This speed allows the satellite to orbit the Earth at a consistent pace, providing various functions such as communication, weather monitoring, and navigation.

On the other hand, rifle bullets travel at a significantly faster speed of 800 km/h. This high speed enables them to cover long distances in a short amount of time, making them effective for their intended purpose, which is typically shooting targets or objects at a distance.

In summary, the speed of Earth's artificial satellite is 100 times slower than the speed of rifle bullets, making the satellite's movement appear gradual and steady in comparison to the rapid and forceful movement of rifle bullets.

This stark contrast in speeds highlights the diverse applications and functions of these two entities, with the satellite's slow and consistent movement serving its specific purposes, while the high speed of rifle bullets fulfills the requirements of firearms for various activities such as hunting, sports shooting, and military applications.
