Given that the A above middle C has a frequency of 440 hertz, the lowest note on a regular piano has a frequency, rounded to two decimal places, of 27.50 hertz. Taking this an octave further down gives a frequency of 13.75, too low for a human ear to hear.
Descending ten semitones, to two Bs below the bottom end of a piano, gives a frequency approximately equal to 13.75/(2^(1/12)10) = 7.72 Hertz, the closest genuine note to a 7.8 hertz frequency.

The speed of sound in air at room temperature is approximately 343 m/s. To find the frequency, you can use the formula: frequency = speed of sound / wavelength. So, the frequency of a sound wave with a wavelength of 78 meters in air at room temperature would be 343 m/s / 78 m = around 4.4 Hz.
in a musical context,early gramophone records were called 78s -this was the speed at which they were played.

50% of 78%= 50% * 78%= 0.50 * 78% (note: 50% = 0.50 in decimal)= 39%To convert 50% to decimal:1. Remove the % sign.2. Divide 50 by 100.
Note that 26x3=78. Next note that 78 divided by 6 is 13. This tells us 78 has 26 and 6 as factors and clearly it is less than 85.
78 * 3 = 234. Note: simple calculations like this one are easier to do with a calculator. If you don't have a calculator available, your computer probably has one for you to use (check under "Programs", "Applications", etc).
Over 60 drums, 78 recorders, 5 flutes and much, much more.
78 + 78 = 156
78 * 78 = 6,084
=2/2.54=.78 inch (Note:1 inch =2.54 cm) ^^ note this is in metric 2 cm would be 3937/5000 but in imperial its around about 4/5 of an inch
