a decrease in the frequency of the sound wave.
Explanation:
When a sound source is moving away from an observer, the observer will hear a lower pitch due to a decrease in the frequency of the sound wave. This is known as the Doppler's effect.
- As the sound source moves closer to the observer, they hear a higher pitch in the reverse process.
- A sound wave transmits vibrational energy from the source to the hearer.
- A sound wave has frequency, amplitude, velocity and wavelength just like other wave types.
- The frequency of a wave is the number of waves that passes through a point at a time.
- This is related to the the wavelength of a wave.
- Waves of a high frequency are known to have short wavelengths and vice versa.
- To hear a low pitch, the source moves away and the wavelength between successive crests and troughs on a wave increases considerably.

Answer:
The function has a maximum in 
The maximum is:
Explanation:
Find the first derivative of the function for the inflection point, then equal to zero and solve for x
Now find the second derivative of the function and evaluate at x = 3.
If 
the function has a maximum
If 
the function has a minimum
Note that:
the function has a maximum in
The maximum is:
The strong nuclear force is the force that holds nucleons, aka protons and neutrons in the nucleus together, through the boson called the gluon. It also holds quarks together, which constitutes the protons and neutrons.
Conductors (something that allows electricity to flow easily) allow for electricity to flow easily. This would be the wires. If you don't have conductors, then you cannot have electricity flow.
Insulators (something that doesn't allow electricity to flow through it) is important because it allows us to be able to touch the cables or place them next to one another and not shock ourselves
Hope this helps
