While we think that our planets formed through the process of core collapse, planets around other stars might or might not have formed from the process of disk instability. Which of the following would make disk instability MORE LIKELY to have occurred around a star? ---

A hotter disk of material

A more massive disk

A more massive star

A larger fraction of solid material in the disk

A previously formed planet

None of these would make disk instability more likely

a coal burning power plant

true tan speed = ang vel x radius

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
