Transverse waves are traveling on a long string that is under a tension of 10.0 n. the equation describing these waves is y(x, t)=( 6.05 cm)sin[( 435 s−1)t−( 45.1 m−1)x]. find the linear mass density of this string.

μ = 0.108 kg/m

Explanation:

Given that

Tension ,T= 10 N

y(x,t)=( 6.05 cm)sin[( 435 s−1)t−( 45.1 m−1)x]

Standard form

Y(x,t)=A sin[ωt−k x]

By compare ,we can say that

ω = 435 s⁻¹

We know that   ω = 2 π f

f=69.23  Hz

k = 45.1 m⁻¹

We know that

λ =0.139  m

We know that the velocity given as

V = f λ

V= 0.139 x 69.23 m/s

V= 9.6 m/s

The linear mass density given as

μ = 0.108 kg/m

This is the mass density.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
