Question

Which of the following types of stars is most likely to end up as a supernova?

Answer 1

I don'd understand what the graphs mean? Is it graph a,b,c, or d? Please help// x

Answer 2

Also, (optional), can you tell me which of those stars are the coolest? Please help because I'm really behind on science coursework.

Answer 3

Alright, so each graph represents the Electromagnetic output of a star. The rainbow section is there to show where visible light falls on the spectrum, but the real importance is the line showing intensity. Now to answer the optional question first, the coolest star is the star emitting the longest wavelength (The hotter an object, the shorter the wavelength emitted). So that means Graph A, with the longest wavelength, is the coolest star.

Answer 4

I'm not strictly sure what the correct answer would be exactly. It could be Graph A, representing a supergiant, or it could be Graph D, representing the hottest of those four stars. Any additional info you can give me?

Answer 5

Thank you so much.
There is no other info given. These were just multiple choice questions:

6. Which of the following types of stars is the coolest?
7. Which of the following types of stars is most likely to end up as a supernova?

So A would be the coolest star (for question 6 above)? Which graph would end up as a supernova (for question 7)?

Answer 6

I'd go with D, hotter stars are larger, and live shorter lives But I can't be certain, because a star about to go Supernova shifts to red from massive expansion

Answer 7

That's okay, thanks for your input. So are you saying #6 would be A and #7 would be D? I didn't quite understand that...

Answer 8

Yep, you got it

Answer 9

Thanks so much!!
Do you think you could help me with one last one? It's about an HR Diagram.

Answer 10

I can give it a shot, sure

Answer 11

Thanks again!

Use the HR diagram below to answer the question.

Which of the following types of stars had a greater initial mass?

Blue main sequence
Orange main sequence
Supernova
White dwarf

Answer 12

I got 'orange main sequence', but I don't think that is correct.

Answer 13

I can't access the diagram without a login

Answer 14

Oh okay hold on one second.

Answer 15

Sorry about that! :)

Answer 16

did you mean supergiant?

Answer 17

Nope, that's all that is written there.

Answer 18

Of course, heaven forbid they have the question make sense. heh

Answer 19

Hahah that's why I have a hard time understanding

Answer 20

I can at least tell you for certain that it is not white dwarf, or orange main sequence

Answer 21

Okay, thank you soo much :) You helped a LOT!

Answer 22

Don't leave yet, I'm going to figure this out :P

Answer 23

Haha okay. Thanks :)

Answer 24

What level astronomy is this?

Answer 25

It's Earth Space science grade 9.

Answer 26

Oh. Supernova then, even that answer technically isn't strictly true

Answer 27

*even though that

Answer 28

Thank you so much. This is all I need. You helped a lot. Thanks.

Answer 29

No problem, good luck!
