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 602 n to 564.00 n, what beat frequency is heard when the hammer strikes the two strings simultaneously? beats/s

Explanation:

Given that,

Frequency in the string, f = 110 Hz

Tension, T = 602 N

Tension, T' = 564 N

We know that frequency in a string is given by :

, T is the tension in the string

i.e.

, f' is the another frequency

f' =106.47 Hz

We need to find the beat frequency when the hammer strikes the two strings simultaneously. The difference in frequency is called its beat frequency as :

So, the beat frequency when the hammer strikes the two strings simultaneously is 3.53 beats per second.

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.

explanation:

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
