Answer: 1.4

Explanation:

2.5/.25 = 10

sqrt(20/10) =1.4

The speed of the wave on the stretched string is 1.41 m/s.

To calculate the speed of the wave, we use the formula below.

Formula:

  • V = √(TL/m).............. Equation 1

Where:

  • V = speed of the string
  • T = Tension
  • L = Length of the string
  • m = mass of the string.

From the question,

Given:

  • T = 20 N
  • L = 0.25 m
  • m = 2.5 kg

Substitute these values into the equation 1

  • V = √(20×0.25/2.5)
  • V = √(2)
  • V = 1.41 m/s

Hence, the speed of the wave on the stretched string is 1.41 m/s.
