A) through steel, but not through air.

D) through steel and air at similar speeds.

Answer 1

@Blu_Seaa This seems to be straight forward, do you get the answer?

Answer 2

I think it's B but I'm not sure.

Answer 3

Just look at the speed of the sound axis, for steel it's some value and for air it's another. Could you write the value for speed of sound in air and steel here?

Answer 4

http://www.usatestprep.com/modules/gallery/files/51/5165/5165.png This is the value of both if that's what you're talking about.

Answer 5

Please type the values here from the graph attached.

Answer 6

Do you mean Steel being 10 and Air being 7 for their value
? I'm sorry but I'm confused.

Answer 7

no problem, look carefully at the bar for steel, it seems to be a different value than 10. For air you're right it's 7.

Answer 8

Oh I'm sorry I meant 20.

Answer 9

you're right, so sound of speed is more in?

Answer 10

Steel.

Answer 11

Yep, so you have the answer now?

Answer 12

A?

Answer 13

how do you say A? Speed of sound in steel- 20, in air it's 10. I would definitely say that sound travels in air based on speed and in real life that's how you are able to talk to your friends...:P
