Astretched string has a mass per unit length of 5.40 g/cm and a tension of 17.5 n. a sinusoidal wave on this string has an amplitude of 0.157 mm and a frequency of 92.2 hz and is traveling in the negative direction of an x axis. if the wave equation is of the form y(x, t) = ym sin(kx + ωt), what are (a) ym, (b) k, and (c) ω, and (d) the correct choice of sign in front of ω?

Part a)

part b)

Part c)

Part d)

here since wave is moving in negative direction so the sign of must be positive

Explanation:

As we know that the speed of wave in string is given by

so we have

now we have

now we have

Part a)

= amplitude of wave

part b)

here we know that

so we  have

Part c)

Part d)

here since wave is moving in negative direction so the sign of must be positive

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.

explanation:

unbalanced force
