I also found that fluorone's Iupac name is xanthen 3 one :) Thanks this might help.

I need to write essey about xanthen 3 one and its derivatives. But the problem is that on internet there is so little data about xanthen 3 one. Does anyone know is xanthen 3 one same as xanthen ? Does it have other name ? Any information would be great help. These are just some questions I need...

So a certain place on chromosome where gene is, it's called locus. And gene contains two allels. So in my book is said that homologous chromosomes contain set of allels and this is what confuses me. So how come is that possible if a single chromosome contains genes and each gene contain two...

Thank you so much for your help :D I got an idea. When you said " the volume you got was of the final solution = 277.78 mL and hence, the water to be added is = (277.78-50)mL = 227.78mL." which means that what upset me was mass concentration of whole solution not only for water, so after finding...

Hello! I have few questions regarding concentrations and I am really confused: 1. Task: How many cm3 of water should be added on 50 cm3 solution of glucose which has mass concentration 2 g/dm3 to get solution that has concentration 0,002 mol/dm3 ? So what happened is that I got correct result...

Yes, I meant that acceleration is negative. My mistake Thank you, you have helped me a lot :)

So If a particle is in a positive area of graph and it has negative velocity and positive acceleration it is traveling to negative axis but slowing down and if it has negative velocity and negative acceleration it is traveling to negative axis but getting more speed because acceleration is...

I have one more problem to solve can someone help me? It goes like this : At t=0, a particle moving along an x-axis is at position x0 = - 20 m. The signs of the particle's initial velocity v0 (at time t0) and constant acceleration a are, respectively, for four situations: (1) +, +; (2) +, - ...

It doesn't matter I think ecastro has explained it :) Thanks for everything :)

These are solutions from Chegg.com so I was trying to understand this by their directions. a) ok, you are right b) and c) Those were their solutions but for me it was logical from graph1) It means, how moving from point 4 to point 5 3) Particle is accelerating (+) and now it wants to slow...

I don't know if points 2 and 6 are equal to initial velocity. Can I read it from graph? Or maybe because they are in the same level ?

So I have problem with understanding graphs in kinematics. Right now I am solving one task and it goes like this : Solution : a) positive , because of positive slope of tangent b) negative c) at 3 and 5 d) a2=a6 > a3=a5 > a1=a4 Magnitudes of...

Thank you .. Some of these books seems very useful :smile:

To be more determined what I don't understand is theory. For example today we were doing " Definite integral of Darboux sum " and I couldn't follow, but in the last semester we were doing for example cauchy sequence and convergence,bolzano weierstrass theorem and these sequences and sums killed...

I don't know is this good place to put this topic anyway I am on the first year of physics and I am struggling with mathematical analysis. I can't understand a lot of thngs that we are doing actually I can't even follow our lectures. I would be really grateful if someone recommend me a book that...
