A phone cord is 3.50 m long. The cord has a mass of 0.200 kg. A transverse wave pulse is produced by plucking one end of the taut cord. The pulse makes four trips down and back along the cord in 0.750 s. What is the tension in the cord?

 T = 1.24 N

Explanation:

The wave velocity is given by

        v = √T /μ

Wave speed is also

     v = λ f

Let's look for the wavelength that you rinse from an oscillation

    λ = 3.5 / 4 = 0.875 m

The frequency is the time of an oscillation

    f = 4 / t

    f = 4 / 0.75 = 5.33 s⁻¹

We equal the equation is

    λ f = √T /μ  

    T = λ²  f² μ  

Linear density is

    μ  = m / L

    μ  = 0.2 / 3.5

    μ  = 0.0571 kg / m

Let's calculate

   T = 0.875²  5.33²  0.0571

   T = 1.24 N

what was the answer?

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
