Two identical piano wires have a fundamental frequency of 678 Hz when kept under the same tension. What fractional increase in the tension of one wire will lead to the occurrence of 6 beats/s when both wires oscillate simultaneously?

Two identical piano wires have a fundamental frequency of 600 Hz when kept under the same tension. You increase the tension in one string until you hear a beat frequency of 6 Hz. What is the fractional increase in the tension?
I will appreciate your kind and best explanation for me. Thanks in advance. 18) Two identical piano wires have a fundamental frequency of 650 Hz when kept under the same tension. What fractional increase in the tension of one wire will lead to the occurrence of 8 beats/s when both wires vibrate simultaneously? 25) (a) A Carnot engine operates between a hot reservoir at 330 K and a cold reservoir at 270 K. If it absorbs 500 J of heat per...
Two guitar strings have a fundamental frequency of 600Hz when kept under the same tension. If the wires are struck at the same time and 6 Beats/sec. is heard what is the difference in the string’s tension?
Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...
Two piano strings have the same length (0.7 cm) and mass density
(16 grams/meter), but the tension of one string is 6% greater than
the first. If beats with a frequency of 5 Hz are observed when the
third (n=3) harmonics of each string are excited simultaneously,
what is the tension of the string with the lower pitch (frequency)?
Answer in newtons to the nearest newton.

In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide extra loudness. For example, the note at 110 Hz has two strings at this frequency. If one string slips from its normal tension of 610 N to 530 N, what beat frequency is heard when the hammer strikes the two strings simultaneously? beats/s
6. Two identical speakers are emitting sound of the same frequency. Speaker 1, located 5 m away, has a sound level of 76 dB. Speaker 2, located 10 m from you, has a sound level of 73 dB. Assuming spherically radiating sound waves, which of the two speakers is producing the sound at higher power? 7a. Express the fundamental frequency of a piano wire fixed at both ends in terms of its tension FT, length L, radius r, and the...
Guy wires used to support tall radio antennae often need to be kept at a specific tension or else the antennae may bend or buckle. The tension tends to decrease over time as the wire ages (and stretches) but on cold days, when the wire contracts, the tension increases. So, to keep the tension within tolerances, the tension in the wire is checked regularly and adjusted if it is found to be outside of tolerances. One way to check the...

Two identical tubes, each closed at one end, have a fundamental frequency of 305 Hz at 25.0 ∘C. The air temperature is increased to 30.0 ∘C in one tube. If the two pipes are now sounded together, what beat frequency results?
