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.

You observe 2 waves named alpha and beta. The alpha wave has a frequency of 5 Hz and the beta wave has a frequency of 2 Hz. Base
MAVERICK [17]

Answer:

shorter wavelength = alpha wave

Explanation:

Given that,

The alpha wave has a frequency of 5 Hz and the beta wave has a frequency of 2 Hz.

We need to compare the wavelengths of these two waves.

For alpha wave,

\lambda_1=\dfrac{c}{f_1}\\\\\lambda_1=\dfrac{3\times 10^8}{5}\\\\=6\times 10^7\ m

For beta wave,

\lambda_2=\dfrac{c}{f_2}\\\\\lambda_2=\dfrac{3\times 10^8}{2}\\\\=15\times 10^7\ m

From the above calculations, we find that the wavelength of the alpha wave is shorter than the wavelength of the beta wave.

How many pints of a 30% sugar solution must be added to a 5 pint of a 5% sugar solution to obtain a 20% sugar solution?
ser-zykov [4K]

You must add 7.5 pt of the 30 % sugar to the 5 % sugar to get a 20 % solution.

You can use a modified dilution formula to calculate the volume of 30 % sugar.

<em>V</em>_1×<em>C</em>_1 + <em>V</em>_2×<em>C</em>_2 = <em>V</em>_3×<em>C</em>_3

Let the volume of 30 % sugar = <em>x</em> pt. Then the volume of the final 20 % sugar = (5 + <em>x</em> ) pt

(<em>x</em> pt×30 % sugar) + (5 pt×5 % sugar) = (<em>x</em> + 5) pt × 20 % sugar

30<em>x</em> + 25 = 20x + 100

10<em>x</em> = 75

<em>x</em> = 75/10 = 7.5

Answer:

i dont even know tbh jk i wont waste ur time unless nvm ok so the answer is The correct answer would be C.10. Krebs cycle is a part of cellular respiration that takes place in the mitochondria. Five energy conversions take place in one complete cycle of the Krebs cycle. These conversions lead to the formation of three molecules of NADH, one molecule of FADH₂ and one molecule of ATP.

C. Metal

You can think of aluminum cans foils
They are both malleable (to morph easily)
They both are ductile (to flatten out)
They both have luster (shiny)
And they both conduct electricity.
