The statement that best describes convection would be:
"After the stove is turned off, convection currents continue to transfer energy through the water for a period of time."
By definition, convection is <span>the movement caused within a fluid by the tendency of hotter and less dense material to rise, and colder, denser material to sink, which results in the transfer of heat.

Answer:
0.283m
Explanation:
Speed (v) = wavelength × Frequency (f)
Wavelength = speed/ frequency
Wavelength = 343/ 1210 = 0.283m
Answer:
The sine waves of the two waves should look the same.
Explanation:
The sine wave formula for a sound wave is given as
y = A sin[2πft + θ]
where
y = The displacement of the wave at time t.
A = amplitude or maximum displacement of the wave during its progression.
t = time
f = frequency of the wave
θ = phase angle/phase shift of the wave which is normally 0 for sound waves
From this information,
It is evident that it is the frequency and time that dictate the exact motion of the wave or behaviour of the waveform. The amplitude only dictates the extent of the wave.
And if the frequency of 2 waves A and B are similar, then even a very different Amplitude cannot change the fact that the two waves will behave similarly, have the same sine curve and have the same movements as the time of progression increases.
Even if the phase angle isn't zero, whatever it is, will not change the fact that the two waves will appear similar to each other, only separated by that phase angle.
Hence, the two waves will look very similar with only the amplitude that shows the extent of displacement, different.
Hope this Helps!!!
The instantaneous speed at 2 seconds =
3 m/s
The average speed over the entire trip is
