Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?

As we know from kepler's law that

here we know that for earth we have time period T = 1 year and its average distance from Sun is 1 AU

so here from above equation we have

from above equation we have

as we also know that

so average distance will be

lexy is right because she has the labeled s

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
