A 520 Hz tone is sounded at the same time as a 516 Hz tone now the beat frequency is 4 Hz.
<h3>What is a frequency?</h3>
The pace of direction changes in current per second is known as frequency. It is expressed in hertz (Hz), a unit of measurement that is used internationally. One hertz is equal to one cycle per second. One hertz (Hz) is equivalent to one cycle per second. A complete alternating current or voltage wave is referred to as a cycle.
- f0=f2=f1 i the formula for frequency .
- then 520 Hz- 516 Hz= 4 HHz.

<h2>Answer : </h2>
20cm spanner is suitable to open this nut , Because we feel easy to apply force at the end of spanner to rusted nut. It means that as the perpendicular distance between force and axis of rotation increase the magnitude of moment also increase.
I think the Answer will helps you.....
Thank you ☺️☺️☺️
The answer is A. 1000 times smaller
The metric prefix mili- is used to signify something 1000 times smaller than a measure. For example in 1 meter there are 1000 milimeters. Therefore; A is correct.
Hope this helped. Have a great night!
