Apiano tuner sounds two strings simultaneously. one has been previously tuned to vibrate at 293.0 hz. the tuner hears 3.0 beats per second. the tuner increases the tension on the as-yet untuned string, and now when they are played together the beat frequency is
1.0s−1.
(a) what was the original frequency of the untuned string?
(b) by what percentage did the tuner increase the tension on that string?

Part a)

Part B)

percentage increase is

%

Explanation:

Part a)

As we know that the beat frequency is

after increasing the tension the beat frequency is decreased and hence the tension in string B will increase

So we have

Part B)

percentage increase in the tension of the string will be given as

now we have

so we have

so we have

percentage increase is

show the wavelengths of a wave. show the crests of a wave.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
