To develop this problem, it is necessary to apply the concepts related to Beat
The Beat is an acoustic phenomenon that is generated by two sine waves interfering with slightly different frequencies. The beat frequency is equal to the difference in the frequencies of the two original waves:
Our values are given as
For the particular case we have two possible frequencies:
Therefore the two possibles frequencies of the other players note are 437.9Hz and 442.1Hz
The magnitude of the adhesive force allows the top block to remain
attached to the bottom when the blocks and the wire are balanced.
The option that must be true is;
Reason:
The tension exerted by the wire attached to the top block = T
Magnitude of the adhesive =
Weight of the top block =
Weight of the bottom block =
Given that with the exertion of the tension, the two blocks remain at rest, we have;
- T =
+
The adhesive causes the bottom block to remain attached to the top block, we have;
Therefore, the magnitude of the adhesive force adds the bottom weight, to the top, weight, which gives;
The magnitude of the adhesive force = The weight of the bottom block
Therefore;
=
