I'm in College Algebra, and sometimes get stuck (math is not my strong suit). Please let me know if you have run into anything good. Thank you!

I'm having trouble understanding some of these basic electrostatic priciples and my book isn't much help. I've put them in a true/false format. If I could get at few answers, it would really help me understand this.

A positive point charge +q is placed at point p to the right of two charges, A and B. The net force on the +q charge is found to be zero. Which of the statements below are true?

A-----------B-----------P
++++++++++++++++++++q

True or False -- The magnitude of the charge A must be smaller than B.

True or False -- Reversing the sign of +q to -q would make the force on it nonzero.

True or False -- B must have the same sign as A and be less in magnitude.

True or False -- B must have the opposite sign from A and be less in magnitude.

True or False -- Either A or B must be positive.

Machines may build organisms in the future. Without the trial-and-error process natural organisms needed in order to evolve, what would the machine-created organisms look like since they are pre-designed and almost totally flawless animals?

Would they look like giant squid-flowers with insect legs? Would they have two thumbs on each hand? Would there be eyes facing every direction? Would it eat food with a spinning blender on top of it's head?

Are they on display for everyone to see? Have they been studied by scientific comunities outside the US?

911 was such an obvious collusion that it made me consider the idea that the moon landings were also manipulated. It doesn't look good.

A student prepares a solution of carbonate-free NaOH. Upon performing a rough titration, the student finds the concentration to be 0.0625 M instead of 0.1000 M. Assuming that the volume of the solution is 950.0 mL, how many grams of sodium hydroxide should be added to the solution to produce a concentration as close as possible the desired 0.1000 M? (Assume that the sodium hydroxide is carbonate-free.)
