What is the frequency of a wave that has a wavelength of 0.39 m and a speed

Physics
1 answer:
gogolik [260]3 years ago
7 0

Answer:

<h3>The answer is option B</h3>

Explanation:

The frequency of a wave can be found by using the formula

f =  \frac{c}{ \lambda}  \\

where

c is the velocity

From the question

wavelength = 0.39 m

c = 86 m/s

We have

f =  \frac{86}{0.39}  \\  = 220.512820...

We have the final answer as

<h3>200 Hz</h3>

Hope this helps you

A wire along the z axis carries a current of 6.8 A in the z direction Find the magnitude and direction of the force exerted on a
Alexeev081 [22]

Answer:

Force is 14.93N along positive y axis.

Explanation:

We know that force 'F' on a current carrying conductor placed in a magnetic field of intensity B is given by

\overrightarrow{F}=\overrightarrow{Il}\times \overrightarrow{B}

where L is the length of the conductor

Applying values in the equation we have force F =

\overrightarrow{F}=6.8\times 6.1\widehat{k}\times 0.36\widehat{i}\\\\\overrightarrow{F}=41.48\widehat{k}\times 0.36\widehat{i}\\\\\therefore \overrightarrow{F}=14.93N\widehat{j}

Thus force is 14.93N along positive y axis.
