Answer:
Explanation:
Givens
The frequency is defined by
Where is the speed of the wave in the string and
is its wave length.
The wave length is defined as
Now, to find the speed, we need the tension of the wire and its linear mass density
Where and the tension is defined as
Replacing this value, the speed is
Then, we replace the speed and the wave length in the first equation
Therefore, the frequency is
This question needs research to be answered. From the given information alone it can't be answered without making wild assumptions.
Ideally, you need to take a look at a distribution (or a histogram) of asteroid diameters, identify the "mode" of such a distribution, and find the corresponding diameter. That value will be the answer.
I am attaching one such histogram on asteroid diameters from the IRAS asteroid catalog I could find online. (In order to get a single histogram, you need to add the individual curves in the figure first). Eyeballing this sample, I'd say the mode is somewhere around 10km, so the answer would be: the diameter of most asteroid from the IRAS asteroid catalog is about 10km.
