a sound wave travels at 330 m/sec and has a wavelenght of 2meters. calcuate the frequency and period

Sergio039 [100]

The frequency of any wave is (speed) / (wavelength).

Frequency = (330 m/s) / (2m) = 165 per second = <em>165 Hz</em>.

Period = 1 / frequency = 1 / (165 per second) = <em>0.0061 second </em>

If a plane has an airspeed of 40 m/s and is experiencing a crosswind of 30 m/s, what is its ground speed in m/s?

Anon25 [30]

<h2>Answer:50 $ms^{-1}$ </h2>

Explanation:

Let $v_{a}$ be the airspeed.

Let $v_{w}$ be the cross wind speed.

We know that,ground speed is the vector sum of airspeed and cross wind speed and airspeed is perpendicular to cross wind speed.

If $v_{1}$ and $v_{2}$ are two perpendicular vectors,the resultant vector has the magnitude $\sqrt{|v|_{1}^{2}+|v|_{2}^{2}}$

Given,

$v_{a}=40ms^{-1}\\v_{c}=30ms^{-1}$

So,the ground speed is $\sqrt{40^{2}+30^{2}}=\sqrt{2500}=50ms^{-1}$
