I'm pretty sure that you are correct !alingy1 said: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 $$\frac{75*10^{-3}kg}{1.8m}$$
Waves are a disturbance or oscillation that travels through space and matter, carrying energy without transporting matter.
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.
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.
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.
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.
