Calculate the velocity of a water wave if the frequency is 390 hz, the wavelength is 5.2m, and the amplitude of the wave is 3.76cm pdf

2028 m/s

Explanation:

Velocity of a wave is given as the product of frequency and wavelength and expressed as

V=fw

Where V denote the velocity, f is frequency while w is walength.

Note that the speed of wave does not depend on amplitude. Therefore, we don't need it for calculation of velocity in this question.

Substituting 390 Hz for f and 5.2 m for wavelength then the velocity is given as

V=390*5.2=2028 m/s

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

a. carbon monoxide from car exhaust

b.particulate matter, such as soot

c.water vapor from a factory smokestack

d.acid rain

these are the answer choices im on that question right now
