Waves, Bungee Jumping, Linear Density Definition

In summary, waves are disturbances that carry energy without transporting matter. Bungee jumping involves falling and being propelled back up by a large elastic cord. Linear density is the mass per unit length of a material, and it can affect the speed and frequency of waves. There are different types of waves including mechanical and electromagnetic waves, which can also be classified as transverse or longitudinal.

Please look a picture.
I think the book made a mistake.
The answer should be 89.9N/m.
Why? Because they calculated the linear density μ wrongly. They should have done $$\frac{75*10^{-3}kg}{1.8m}$$

I'm pretty sure that you are correct !
 

Related to Waves, Bungee Jumping, Linear Density Definition

1. What are waves?

Waves are a disturbance or oscillation that travels through space and matter, carrying energy without transporting matter.

2. How does bungee jumping work?

Bungee jumping involves jumping off a tall structure while connected to a large elastic cord. As the jumper falls, the cord stretches and then recoils, propelling the jumper back up. This process continues until the energy of the fall is dissipated.

3. What is the definition of linear density?

Linear density is the measure of mass per unit length of a material. It is calculated by dividing the mass of an object by its length.

4. How does linear density affect the behavior of waves?

The linear density of a medium can affect the speed and frequency of waves traveling through it. Generally, waves travel slower in materials with higher linear density and faster in materials with lower linear density.

5. Are there different types of waves?

Yes, there are several types of waves including mechanical waves (such as sound and water waves) and electromagnetic waves (such as light and radio waves). Waves can also be classified as transverse or longitudinal, depending on the direction of the disturbance in relation to the direction of wave propagation.
