Answer:
439 Hz
Explanation:
= Frequency of first wave = 440 Hz
F = Beat frequency = 1 Hz
= Frequency of the instrument
The beat frequency is the difference of the two waves which are interacting with each other

The frequency of the instrument is 439 Hz
Idk but it must be hard tho

Answer:
0.11m/s
Explanation:
To solve the exercise it is necessary to apply the concepts related to the conservation of both: kinetic and spring energy(Elastic potential energy), in this way
Kinetic Energy = Elastic potential energy


Where,
m=mass
v=velocity
k=spring constant
x=amount of compression
Re-arrange the equation to find the velocity we have,




Therefore the maximum speed of the bananas is 0.11m/s
