Answer:
Greater than
Explanation:
The Wavelength will be higher than what will be heard without any motion on the boat due to the Doppler Effect, which is the change in the frequency of a sound wave whenever there's a relative motion between the source of the wave and observer. The amount of shift in frequency depends on the speed of the source towards the observer; the higher the velocity of the source, the higher the shift.
Answer:

Explanation:
Angular speed and linear speed is related to each other as

here we know that


now we have



Now we know that moment of inertia of the system is given as
![I = (2M + m)R^2 [tex][tex]I = (2\times 0.22 + 0.0045)(0.08)^2](https://tex.z-dn.net/?f=I%20%3D%20%282M%20%2B%20m%29R%5E2%20%5Btex%5D%3C%2Fp%3E%3Cp%3E%5Btex%5DI%20%3D%20%282%5Ctimes%200.22%20%2B%200.0045%29%280.08%29%5E2)

Now angular momentum of the system is given as


Answer:
vector
Explanation:
The position of a particle is vector
It depends on if it is a sound wave or light wave
