Soap was made for cleaning washing and such. It’s important to use soap in the process of cleaning your clothes because not only does it usually leave a better scent but it helps take out stains and such. That’s why we use soap to clean our bodies, faces, dogs, certain materials. So that the dirt and any other debris comes off. Think about washing the dishes, you don’t wash them with only water. You use soap because it’s the most logical effective way to clean things.

Answer:

Water alone can't clean clothes because it won't attach to molecules of grease and dirt.

Explanation:

The surfactants it contains are made of molecules that have two different ends. One end is strongly attracted to water; the other is attracted to oily substances like grease.

In a certain time, light travels 4.96 km in a vacuum. during the same time, light travels only 3.36 km in a liquid. what is the
Natali5045456 [20]

the refractive index of the liquid is 1.476

The refractive index, which has no dimensions, measures how quickly light passes through a substance.

It can also be described as the difference between the speed of light in a vacuum and a medium.

Refractive index is equal to the product of the light's liquid and vacuum speeds.

Therefore.

speed of light in vacuum = 4.96 km/t

speed of light in liquid = 3.36 km/t

Refractive index = 4.96/3.36

Refractive index =1.476

Therefore, the refractive index of the liquid is 1.476
