"in the paper making process, the pulp is strained to create the initial textured/brittle paper, but the process doesn't end there. The textured paper must be put through high pressured steam rollers to create the smooth paper you've come to know. This setting process causes all the fibers to be pressed flat and packed together evenly on the surface. When paper gets wet, it "unsets" itself, breaking up the tension that held the fibers together, again causing the uneven texture it initially had." Got this from reddit
The frequency of the 10th harmonic is 800 Hz
Explanation:
The frequency of the nth-harmonic for the standing waves in a string is given by the equation

where
is the fundamental frequency of the string
In this problem, we are given the frequency of the 3rd harmonic:

Which can be rewritten in terms of the fundamental frequency

So we find
:

Now that we have the fundamental frequency, we can find the frequency of the 10th harmonic, with n = 10 :

Answer:
Lithium and francium belong to the same group because they both have the same number of valence electron. Having the same number of valence electron puts them in the same group. Group members possess similar properties. So Lithium and francium have similar properties because they have the same number of valence electron.
