chemistry
What are some applications of Nuclear Chemistry in Medicine? So far I've found - X-rays - Radioactive tracers - Gamma radiation can be used to treat cancer and other diseases

chemistry
What are the advantages of a gas as a coolant? (instead of heavy/normal water) (in a fission reactor)

chemistry
say A -> B + 5kJ would reactants have more enthalpy or products have more enthalpy? I think first, the delta H would be negative. So H final must be less than H initial. So reactants have more enthalpy?

chemistry
Is there a salt bridge in a fuel cell? I think there isn't one because hydroxide ions and hydrogen ions are in the water, so they can move around freely already.

physics
They all have values around there, so I'm sure the proportionality is something like that. But I'm supposed to graph it to show this proportionality and I'm not sure what goes on the axis. Is the y-axis f and x-axis 1/length^0.5 or is the y-axis 1/f^2 and x-axis le...

physics
Using the data below, suggest a proportionality statement. Length (cm) Frequency (Hz) 100 0.46 80 0.52 60 0.62 40 0.74 20 1.01 I think it's f ¡Ø 1/¡Ìlength (one over square root of length) or is it l ¡Ø 1/f^2 By the way, the length is...

chemistry
Write the oxidation and reduction half-reactions of a corroding galvanized nail exposed to rain. The question says "galvanized" so its zinc. Zn(s) -> Zn2+(aq) + 2e- potential: +0.76V rain is slightly acidic, so i thought it would be O2(g) + 4H+ + 4e- -> 2H2O po...

i got to write an essay about my history. Like, origin/culture, heritage etc...But I don't know that much about my origin/culture, heritage, so anyone want to help me?

ICS
I need help solving this question. "Two charges are 10 meters apart. The charge on the positive particle is 1.0 C and the negative charge is 10 Coulombs. Calculate the magnitude of the electrostatic force of attraction between these two charges."

music
I need help studying for my term. I need to know how to identify stuff on a staff or musical notation. Like clefs, notes, signatures, etc... How should I remember these? Are there any online resources? I also need to define terms. How do I remember these terms for the finals?

Algebra
Which point is a solution of the system? Y=x-9 X+2y=3

math
where does the "3" go then? 3x^2+3 = 3 x(x^2 + 1) = "3"(x+i)(x-i) because the answer is: (x-1)(3x-1)(x+i)(x-i)

math
how do you factor the polynomial 3x^4-4x^3+4x^2-4x+1? i got (x-1)(3x-1)(3x^2+3) but the answer is (x-1)(3x-1)(x+i)(x-i)

How to graph a system of linear inequalities. How to figure out the points. y<-5x-7 y>2x+7 Plot the line y=-5x -7 I assume you know how to do that. Now, since y is less than that line (look at the original equation), the area of allowability is BELOW that line. Now plot ...
