It's worth knowing that the dilution factor, DF, tells you the ratio that exists between the volume of the diluted solution and the volume of the stock solution. DF = V diluted V stock In your case, the volume …

You mean the naphthalene cakes that you see on the bottom of urinals? The answer to your question is "not much". Of course the people who supply "moth balls" will machine the napthelene so that it …

And thus the alkanes form a so-called homologous series whose general formula we can specify as #C_nH_ (2n+2)#...and such alkanes have reasonably similar chemistry. Stick a functional group in …

So if it is in the middle of the shape then it must be in the middle of the x-intercepts. In other words; it is the mean (average) value of #x=1" and "x=5#

Breathing from your belly is completely normal. In fact, all mammals do this. Diaphragmatic breathing, also known as belly breathing and known scientifically as eupnea, is breathing that is done by …

T = 1/6 mg v = 2 sqrt((gh)/3) This is idealised, eg assumes that the strings remain in the vertical position. But this does serve as a FBD. With x as the key co-ordinate, which is positive pointing downward: …
