Trust me, i'm a k12 student and its motor
Answer:
b) 1.67×10^7 m/s
Explanation:
The solution is attached in the attachment section
It’s c because it’s not Control so that means that it would be broken and non fix able
Answer:
refraction
Explanation: hope this helps :)
V=wave velocity , <span>f= frequency, </span><span>λ=wavelength </span>
<span>Use it to find corresponding wavelengths for</span><span> f=28 Hz </span>
<span>λ= v/f= 337/28=12.036 m
</span>
<span>for f=4200 Hz </span>
<span>λ= v/f=337/4200= 0.08 m </span>
<span>So max. wavelength is 12.036 m and </span>
<span>Min Wavelength is 0.08 m </span>
<span>So the range is between .08 m and 12.036 m
</span>Hope this helps.
