Answer:
Please see below as the answer is self-explanatory.
Explanation:
- In order to have a destructive interference, the path difference between the sources of the sound, must be equal to an odd multiple of the semi-wavelength, as follows:
- The minimum posible value for this distance, is when n=1, as it can be seen here:
- In any traveling wave, there exists a fixed relationship between the wave speed, the frequency and the wavelength:
- Therefore, assuming that the speed of sound keeps constant, if the frequency is increased, in order to keep the right side of the expression above balanced, λ must be decreased.
- As the smallest separation that produces destructive interference is directly proportional to the wavelength, this means that this separation will decrease if the cellists produced a note with a higher frequency.
Answer:
B 150g
Explanation:
b 150g mass of water remains the same when it changes state
Jogging side by side since the speed is equal and the direction is the same i.e same velocity
'Pressure' is (force) / (area).
The only choice with those units is #1 .
The ability to reproduce is essential for a species, but not for an individual. There are some people that can't reproduce, but they're still alive!
