Sorry, I don't know why I said that. The molecules that are produced by the light-dependent reactions are ATP and NADPH. I know that you need both to make Ribulose 1,5-Bisphosphate in the Calvin Cycle, so that means shutting off the light would decrease the levels of Ribulose 1,5-Bisphosphate...

Homework Statement An illuminated suspension of chloroplasts is actively carrying out photosynthesis. What would happen to the levels of 3-phosphoglycerate and Ribulose 1,5-Bisphosphate if the light was suddenly switched off? Homework Equations The Attempt at a Solution I...

Well that other cyclic structure could be in the way...so I'm guessing the answer is no reaction?

Homework Statement I am working on a homework problem for my Organic Chemistry class. In one particular question, our teacher asks for the expected product when http://img301.imageshack.us/img301/5986/homeworkproblem1qu8.th.jpg reacts with sodium cyanide. Homework Equations N/A The...

So (494843 + 101325)=(10^3)(9.8)(h) h=60.8m Still not right...

Should it be rho*g*h + the atmospheric pressure?

Nope...didn't work. I tried P1=101,325 Pa, V1=(pi)(r)^2(h)=pi(0.008795)^2(2.1)=0.000528 P1V1=53.55 Then V2=(pi)(0.008795)^2(0.43)=0.000108 So P2=53.55/0.000108 = 494843 Plugging that into my first equation, 494843=(10^3)(9.8)(h) h=50.5m It wasn't correct :(

Oooh I see where you're going with this...So calculate the pressure of the air after the tube is lowered, which would be the same as the water pressure? I'm not really sure what I'd use for P1 though. Would I use the pressure of air at sea level?

Homework Statement A 2.1 m long glass tube that is closed at one end is weighted and lowered to the bottom of a freshwater lake. When the tube is recovered, an indicator mark shows that water rose to within 0.43 m of the closed end. Determine the depth of the lake. Assume constant temperature...

ah ha! that equation worked! I'm a total newb at physics so I wasn't aware there was a separate equation for the moment of inertia for a disc Thank you so much!

Homework Statement A car is designed to get its energy from a rotating flywheel (solid disk) with a radius of 1.00 m and a mass of 425 kg. Before a trip, the flywheel is attached to an electric motor, which brings the flywheel's rotational speed up to 4000 rev/min. (a) Find the kinetic...

Homework Statement Draw an LCAO representation of all of the bonding orbitals for C2H2O. Be sure to clearly state the hybridization of the two carbons and the oxygen in addition to drawing the orbital representation. Also show clearly what orbital any unshared pairs occupy. Homework Equations...
