Answer:
M = 4.01
Step-by-step explanation:
5m = 20.05
M =20.05/5
M = 4.01
Since you are looking for the speed, you need to rearrange the formula which is f = speed / wavelength. That should give you speed = f (wavelength.) All you need to do next is to substitute the value to the following equation. speed = 250 Hz (6.0m) that should leave you with 1500 m/s which is very fast.
Answer:
B
Step-by-step explanation:
When multiplying exponents with the same base, you add the powers together.
In B, that is exactly what they are showing when they do:
D is your answer, it equals 9 :)
