D. 35 m/s

**THanks! :D

Answer 1

sorry for prvious exercise, the right formula is:
\[\Large fT = 1\]

Answer 2

please wait I'm checking your previous exercise

Answer 3

ok!:)

Answer 4

ok! After my correction, we have:
\[\Large \lambda f = v\]

Answer 5

okay! :D

Answer 6

how do we plug in?

Answer 7

we can write this:
\[\Large v = 2.5 \times 10 = ...\]

Answer 8

wehave to replace \lambda with 2.5 meters and f with 10 Hz

Answer 9

okay! so we get 25? so our answer is choice C?

Answer 10

yes! correct!

Answer 11

yay!! thank you:)

Answer 12

thank you!! :)
