Four beats per second are heard when two notes are sounded The frequency of one note is 420 Hz what is a possible frequency of the other note?

The beat frequency is the difference of the overlapped frequencies. Thus the other frequency is either 445 or 435 Hz. For detail, read the wikipedia page on Beat(acoustics)

A 520 Hz tone is sounded at the same time as a 516 Hz zone How many beats per second will you hear?
Beats = l f1 - f2 l = l 520 - 516 l = 4 beats per sec
The unit which frequency is measured?
Frequency is measured in Hertz (Hz). It means number of (what you're counting) per second. Ie. waves, revolutions, beats ect.
A nurse counts 76 heartbeats in one minute. What are the period and frequency of the oscillations?
76 beats per minute = 76/60 = 1.267 beats per second = 1.267 Hz Period = 1 / frequency = 1 / 1.267 = 0.789 s
How does interference of sound relate to beats?
Beat is defined as the basic unit of time, the pulse (regularly repeating event), of the mensural level in music theory. It occurs due to interference or superposition between two waves of very slightly different frequencies and sounded together.
What would the beat frequency be if you added tones of 880 Hz and 882 Hz?
The number of beats that we hear per second is the beat frequency. It is equal to the difference in the frequencies of the two notes. In this case: Beat frequency = 882 Hz - 880 Hz = 2 Hz. This means that we will hear the sound getting louder and softer 2 times per second.
Beats are produced when two tuning forks one of frequency 240 Hz and the other of frequency 246 Hz are sounded together The frequency of the beats is?
6Hz
Beats can be heard when two tuning forks?
Almost the same frequency and are sounded together.
Beats are produced when two sources are sounded together these sources should have what frequency?
The two frequencies should be near one another.
What do you hear when two almost identical frequencies are sounded together?
You hear 'beats', or pulses, and these pulses happen at a frequency which is the difference between the frequencies of the nearly identical tones.
Two tuning forks are struck at the same timeone tuning fork has a frequency of 20 hz while the second tuning fork has a frequency of 226 hz how many beats will result?
11.3 beats
A 1056-Hz tuning fork is sounded at the same time a piano note is struck You hear three beats per second What is the frequency of the piano string?
Could be 259 Hz.Could be 267 Hz.
A 520 Hz tone is sounded at the same time as a 516 Hz zone How many beats per second will you hear?
Beats = l f1 - f2 l = l 520 - 516 l = 4 beats per sec
When two tuning forks of 125 hz and 145 hz respectivelyare sounded simultaneously how many beats per second are heard?
20Hz and 270Hz

A 1056 tuneing fork is struck and you hear 3 beats per second what is the frequency of the piano?
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.
