Sorry for not clarifying - the absorption of the solute in the blood. I'm using an LED and a photodiode for detection. Would I just use the molar extinction coefficient of the blood?

How would I get the most accurate results?

I'm currently doing a project that involves beer-lambert's law and am confused as to what it actually calculates. So far, my intuition goes as follows: The molar extinction coefficient is for the solvent at a specific concentration and wavelength. In this case, it is blood. And if you have to...

Oh, I got it. Thanks for the help.

I have the image attached.

Sorry, the image is so large, but is this what you mean?

What's the apparent origin?

Since it has a greater velocity at the end of the track

Potential and kinetic energy.

Potential and kinetic energy.

The overall energy, so it's the greater mechanical energy.

2 frictionless tracks have equal length bumps with one going up and the other down. Halfway through the track which one has more energy? Assuming that they started at the same height, I thought that they had the same amount of energy, but since Ball B ends up having a greater velocity at the...
