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
Power is the work done per unit time. Therefore,

Therefore,
An example of biological weathering is the widening of gaps
in rocks caused by tree roots since pressure or stress is exerted on the
rocks due to the growing plant roots. The pressure is exerted by a biological
process (i.e., growing roots), even though the process is physical.
Plants and animals and its action speeds up mechanical and or
chemical weathering, which in turn causes biological weathering.
<span>With the help of the chemicals
that are produced by the tiniest bacteria, algae and liches, the rocks which they
live in are also broken down by them in order to get the nutrients they need.</span>
It goes from Kinetic when it is at rest to potential on its way to the bottom. There is also friction but very few people care about that.
