A sound wave is traveling at a speed of 330 m/s. If the frequency of the wave is 660 Hz, what is the wavelength of the sound wav

saul85 [17]

Answer:

The wavelength of the sound wave traveling at 330 m/s is 0.5 m.

Explanation:

Given:

Speed of sound wave is, $v=330\ m/s$

Frequency of the sound wave is, $f=660\ Hz$

Speed of a sound wave is related to its frequency and wavelength as:

$v=f\lambda$ , where, $\lambda$ is the wavelength.

Now, plug in 330 for $v$ , 660 for $f$ and solve for $\lambda$ . This gives,

$330=660\lambda\\\lambda=\frac{330}{660}=0.5\ m$

Therefore, the wavelength of the sound wave traveling at 330 m/s is 0.5 m.

Venus moves faster than earth because it move with a higher speed as compared to earth.

<h3>Is Venus move faster than earth?</h3>

Venus move with the speed of 35.02 km/s while on the other hand, the earth moves with the speed of 29.78 km/s. So due to more speed of Venus, the Venus completes its revolution earlier than earth.

So we can conclude that Venus moves faster than earth because it move with a higher speed as compared to earth.

A hiker walks 14.91 m, N and 4.40 m, E. What is the magnitude of his resultant displacement?

Rashid [163]

Givens.

• 14.91 meters North.

• 4.40 meters East.

First, make a diagram to visualize the vectors and the resultant displacement.

In the figure, the purple vector d represents the resultant displacement, which horizontal component is 4.40m and its vertical component is 14.91m.

Let's use the following formula to find the resultant.

$d=\sqrt[]{(y_{})^2+(x)^2}$

Where y = 14.91 and x = 4.40.

$\begin{gathered} d=\sqrt[]{(14.91m)^2_{}+(4.40m)^2} \\ d=\sqrt[]{222.31m^2+19.36m^2} \\ d=\sqrt[]{241.67m^2} \\ d\approx15.55m \end{gathered}$

Therefore, the magnitude of the resultant displacement is 15.55m.

But, the resultant displacement refers to the vector, which is the following

$d=(4.4i+14.91j)m$
