Answer:
1.001 m
Explanation:
We have to find the least measurement of the instrument.
In this case the least measurement = 1 mm
= (1/1000) m
= 0.001 m
The measurement that is precise from this instrument should be to the nearest thousandth when taken in meters.
Therefore the answer is: 1.001 m
The answer is C. Mountains. I hope this helped!
during free fall acceleration doesn't depends on initial speed
in free fall acceleration is given by
so for all cases of initial speed its acceleration is always equal to "g" and magnitude equal to 9.81 m/s^2
Let's call
the frequency of the nth-harmonic and
the frequency of the (n+1)th harmonic, wish is the next harmonic.
Since the frequency of the nth-harmonic is n times the fundamental frequency f1:
then the difference between two successive harmonics is equal to the fundamental frequency of the tube:
so, by using 350 Hz and 280 Hz as successive harmonics, we find the fundamental frequency of the tube:
The wavelength of the first harmonic is twice the length of the tube:
And since we know both frequency and wavelength, we can find the speed of the wave in the tube, which is the speed of sound in the gas in the tube:
