Question

What is the speed of sound in dry air at 0°C?
a.316 meters/second
b.331 meters/second
c.346 meter/second
d.373 meters/second

Answer 1

do you know the formula to figure this out?

Answer 2

i just googled it

it's

c = (331.3 + .0606T)

where c is the speed of sound, and T is the temperature

Answer 3

know how to go from here?

it's only about 1 more step and you get the answer ;)

Answer 4

that should be .606 not .0606

c = (331.3 + .606T)

better

Answer 5

haha not really, this is confusing to me

Answer 6

oh thank you!

Answer 7

alright well, the formula is

c = (331.3 + .0606T)

you want to find c (the speed of sound)

you know T, as it was given

basically just plug in T

Answer 8

man i copied and pasted it wrong again

c = (331.3 + .606T)

fixed, again lol

Answer 9

oh okay, can you help me with a few more problems please?

Answer 10

ask away

Answer 11

What is the speed of sound at a temperature
of 56°C?
a.316 meter/second
b.331 meters/second
c.365 meters/second
d.373 meters/second

Answer 12

same thing as before

just plug in T = 56

Answer 13

by the way, what was your answer for the first problem?

Answer 14

i don't get it, like how would you set it up?

Answer 15

alright, i googled the equation, and this is what I got

c = (331.3 + .606T)

this equation will tell you what the speed of sound is in dry air

Answer 16

the equation depends on T, the temperature. This is what is being given to you in these problems.

All you need to do is plug in the value for the temperature it gives you.

For instance, in the first problem where the temperature was 0 degrees:

c = (331.3 + .606T)
c = (331.3 + .606(0))
c = 331.3 + 0
c = 331.3

therefore, the answer to the first question was B, 331

Answer 17

so it would be d?

Answer 18

nope, not D

Answer 19

try again :)

Answer 20

i got 331.3 which would be B correct?

Answer 21

yup, for the 1st problem

what about the 2nd problem?

Answer 22

lemme see :)
