How would you use the figure that I am given to find the Vrms ??

Homework Statement Fractions of Molecules in an Ideal Gas with Speeds Less than Various Multiples of v/v_{\rm rms} in the textbook. The molar mass of {\rm{N}}_2 is 28.0 {\rm{ g/mol}}. For a gas of nitrogen molecules {{\rm{N}}_2 } , what must the temperature be if 94.7\% of all the...

i said 0 + q0Va = 1/2mv^2 + q0Vb

Homework Statement Two stationary point charges + 3.00 {\rm nC} and + 2.00 {\rm nC} are separated by a distance of 50.0 \rm cm. An electron is released from rest at a point midway between the two charges and moves along the line connecting the two charges Homework Equations What is the...

Now i sent you a pm! lol

This 15 db difference corresponds to a 1.5-Bel difference. This difference is equivalent to a sound which is 10^1.5 more intense. Always raise 10 to a power which is equivalent to the difference in "Bels. Or less intense in this case thus dividing by 1.

Its easy! Its 1/10^2.5 Sorry that was for me! Its 1/10^1.5 for you 90--->75 Mine was 90-65

Wahey Tis right, Thanks a lot ;)

Then for the q said, I2 =(1/2Io)(.25302) and found it to be 37.751

I got Io=298.41

So I_1 = 1o/2 => I_3=(.91)(.545).Io/2 Correct? thanks a lot

Im taking a break, think "Fringes from Different Interfering Wavelengths" may be answerable! If i hit 60 i'll be proud! lol ;)

Sure i got it...... Nah i think I'm retarded, on 40%.. Still can't get the polarizer one or this one or the last one lol

Shouldn't be doing your Homework 3 and half hours before its due.. tut tut:-p

So I am getting say. When passing through first filter.. I_1=Io I_2=.91Io I_3=(.91)(.545)Io ??
