A comet from the outer part of the solar system has a very long orbit. According to Kepler's second law, what is true about the orbit?

-As the comet approaches the sun it speeds up.

-As the comet approaches the sun it slows down.

-The speed of the comet is constant.

-The comet is moving in a circle.

-The orbital speed of the comet varies in no predictable way.

Welcome to hypography, ambere. :)

 

These appear to be science homework questions, so I’ve moved them to this forum.

 

You’ll learn less effectively if just given the answers to questions like this, so why don’t you post, in your own words, what you think Kepler’s second (which addresses the changing speed of orbiting bodies) and third law (which addresses the relationship of their distance from the Sun (semimajor axis) and the period of their orbit say, then try answering the questions based on your understanding of the laws?

 

Then we can jump in and tell you if you’re right or wrong, and why.
