Answer:

1.52 L

Explanation:

P1V1T2=V2P2T1

V2=V1T2/T1

Fill in with given values then solve

We can check this by knowing that V and T at constant P have a proportional relationship. Hence, this is correct.

- Hope that helped! Please let me know if you need further explanation.

What is the frequency of a wave traveling west with a velocity of 414 meters per second and a wavelength of 1.8 meters? hertz
LuckyWell [14K]

Answer:

230hz

Explanation:

Hello,

To solve this question, we gave to use the relationship between velocity-frequency-wavelength to find the frequency in this question.

V = Fλ

V = velocity or speed of the wave

F = frequency of the wave

λ = wavelength of the wave

Data;

V = 414m/s

λ = 1.8m

f = ?

V = fλ

f = v/λ

f = 414/1.8

f = 230hz

The frequency of the wave is 230hz
