Question

Which statement best defines why sound waves are mechanical waves?
A.They require a medium in which to travel.
B.They can travel through a vaccum.
C.They can travel only through solids.
D.They can travel through gases.

Answer 1

A.They require a medium in which to travel.

Answer 2

Are you positive?

Answer 3

yup

Answer 4

If the frequency of a sound wave is 250 hertz and its wavelength is 1.36 meters, what is the wave's velocity?

Answer 5

frequency=1/Time wavelength=1.36m is distance travelled now you might get velocity. . .

Answer 6

How do you solve it?

Answer 7

you have distance you have time =1/frequecy distance over time is speed. . .

Answer 8

So its 1/250

Answer 9

\[v=\nu \times \omega \]
where nu is frequency and w is wavelenght

Answer 10

huh?

Answer 11

just multiply frequesncy with wavelength and you have the answer

Answer 12

whats the frequency and wavelength

Answer 13

If the frequency of a sound wave is "250 hert"z and its wavelength is "1.36 meters", what is the wave's velocity?

multip[ly them. . . :P :|

Answer 14

340??

Answer 15

yup

Answer 16

thank you!!

Answer 17

What is the speed of sound at a temperature
of 56°C?

Answer 18

speed of sound doesnt depend upon temperature. . .

Answer 19

Its 365 meters/second
