We should see (and have now detected with LIGO) gravitational waves
I believe it would be false
For the majority of instruments f = n f0 where f is the resonating frequency, n is any whole number and f0 is the fundamental.
<span>This applies to trumpets, violins, flutes and a broad range. </span>
<span>In such a </span>case<span> the first harmonic would be at n=1 and the second harmonic would be at n=2 </span>
<span>which gives a frequency of 84 Hz</span>
Answer: 245 meters
Explanation: 49 ? Meters
over over over
1 5 seconds
Cross multiply- 49 times 5 divided by 1 which equals 245
