Awave with a frequency of 60 hz is traveling along a string whose linear mass density is 230 g/m and whose tension is 65 n. if the wave is to transfer energy at a rate of 75 w, what should the amplitude of the wave be?

To develop this problem we will use the concepts related to Speed in a string that is governed by Tension (T) and linear density (µ)

Our values are given as:

Replacing we have that the velocity is

From the theory of wave propagation the average power wave is given as

Where,

A = Amplitude

Angular velocity

Replacing,

Therefore the amplitude of the wave should be 0.0165m

the word that best describes martin luther king jr.'s tone in the video is dignified

martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
