Which force primarily acts on a natural or artificial satellite to keep it in orbit around a planet

Biology
1 answer:
rjkz [21]3 years ago

Answer:

Gravity

Explanation:

When its altitude is matched by the pull of the Earth's gravity, a satellite circles Earth. The satellite will fly off into orbit in a straight line or crash down to Earth without this equilibrium.

By juggling two things, a satellite retains its orbit: its velocity (the speed it takes to travel along a straight line) and the gravitational force on it that the Planet provides. To resist the greater gravitational force, a spacecraft orbiting closer to the Earth needs more velocity.

<h3>What is common ancestry?</h3>

Common ancestry refers to blood relationships. Thus, two species may have common ancestry if they are related by blood.

According to Charles Darwin, common ancestry explains the similarities between different species.

However, a rapid increase in the number of species with a common ancestor, characterized by great ecological and morphological diversity results from adaptive radiation.

Thus, Charles Darwin's finding that the finches on the Galapagos islands looked different from the mainland finches despite their common ancestry from South America is an example of <u>C. adaptive radiation</u>.

faust18 [17]

Answer:Organisms rely on each other to sustain the ecological environment, something that humans have been lacking in. So, in general, organisms are interdependent because they have no choice. There are more particular instances (mutualism, symbiosis, etc.) where the connection is more local and direct.
