Almost the same frequency and are sounded together.
If they are of the exact same frequency, they will sound as unison and no beats can be heard.
Are not playing the same frequency
20Hz and 270Hz
6Hz
Number of beats heard in one second will be got by the difference between the parent frequencies. Hope you have given wrong data for parent frequencies. The first one has to be 220 Hz and the other is 226 Hz. Hence 6 beats will be heard in one second. If you say 20 is the right one then difference will be 206. If 206 beats get produced in one second it will not be named as beat at all. Moreover our hearing could not recognize this as beating at all. So better correct the given data.

A sound known as a "beat frequency" will be heard when two sounds of almost (but not quite) the same frequency are mixed together. This is commonly heard when tuning a stringed instrument (such as a guitar) into itself, or when tuning to a standard pitch generator. If the string is vibrating at exactly the same frequency as the standard, then no beat frequency is heard. If the string is vibrating at a just slightly different frequency from the standard, then the interference between the two sounds is heard as a regular "beat". The frequency of the beat is exactly equal to the difference between the two frequencies i.e. if the standard is 440 Hz and the string is vibrating at 441 Hz, then a beat frequency of 1 Hz will be heard.
Two babies! Twins!!!
It can, if there's another source of sound nearby, vibrating at the natural frequency of the tuning fork. Example: Two tuning forks with the same natural frequency. The first one can be set vibrating by whacking it against the edge of the table, whereupon the second one will vibrate because it resonates with the first one.
A tuning fork is a two-pronged steel device that is used by musicians. When a 1056-Hz tuning fork is struck at the same time a piano note is played, and 3 beats per second is emitted, the frequency of the piano is 1059 Hz.
The beats are the sum and difference of the components ... (A + B) and (A - B).If something really non-linear is also going on, you also get (2A - B), but we'llleave that alone for right now.That pair of forks produces beats at 2 Hz and 990Hz .
Not much, really. You strike yours where you are and I'll strike mine 3,000 miles away at precisely the same moment. Suddenly...nothing happens. I think you're really asking about resonance, which can, in fact, be very powerful. Sound waves reinforcing each other. Works for light, as well. It's called a "laser."
