Homework Statement 20.0 mL of a 0.1 M solution of sodium hydroxide is titrated into 50.0 ml of the 0.14 M HOBr solution. Calculate the pH of the resulting solution. ph of HOBr is 4.74 Ka is 2.3e-9 Homework Equations [H+] = ka(a/b) -log[h+] = ph ka*kb=kw The Attempt at...

no its for AP Physics B which is algebra based. I know Calculus, well two semesters worth. How would I solve it using calc?

Homework Statement A passenger is rising in a hot air balloon at a constant 2m/s. The passenger realizes she forgot her camera. A second person on the ground below the balloon throws the camera straight up when the balloon is 2.5m off the ground. What is the minimum velocity the camera...

oh and yes I do exercise regularly, but its almost counterproductive for me. Once I am done with my weight lifting workout I am shot and sitting down with a physics book becomes awefully hard. Thats why I try and do my studying before I touch a weight or else I am screwed.

thanks guys for the advice btw...I may have gone a bit too far when I talked about the sopohomores taking quantum physics, but if you guys have ever been on the artofproblemsolving.com there are kids taking complex analysis by sophomore year in high school. They did Calc BC in like 7th...

Hello all. Im pretty new to the physicsforums, but nonetheless am amazed at the extent of intellectual curiosity in this community. Anyway this is my question. At my high school I guess I am considered "elite" in Math, Science, History,..not english...I suck at that. I taught my self...

wow. I feel dumb. I should have seen that, but thank you. I will be taking AP Physics in the fall so I wanted to enter sharp by prepping over the summer. I had a very poor physics instruction the previous year. My teacher never taught us the theory and relationship with mathematics of many...

well no in that case you could choose any a and still get the correct displacement. But is that a legal move? I've never seen that type of maneuver in a textbook. Mathematically I know its valid its just that it seems like your just manipulating so that it gives you that answer your looking...

nothing. all the a term does is to increase/decrease the value of the displacement.

Homework Statement A volcano shoots a lava bomb straight upward. Does the displacement of the lava bomb depend on your choice of origin and/or your choice of positive direction? Homework Equations y(t)=vt-\frac{1}{2}gt^2 The Attempt at a Solution first I tried just remembering...

Thank you for all your input

Im most inclined to rockets, but I am reluctant to specialize. I want to have a broad understanding of weapons design in general. But then again, I don't want to build just bombs for the next 40 years. Sure I'd like to design missiles, but I'd also like to work on making better armor or...

I DONT WANT/LIKE KILLING PEOPLE I believe the more powerful weapons their are in the hands of relatively just countries, the more peace there is. If two countries have nukes do you think either would really want to start a fight that will end in Mutually Assured Destruction? NO! But...

And yes I do enjoy engineering. I have been tinkering with stuff since I was like 6. I hacked my Xbox at the age of 11. Got my A+ comuter certification before freshman year of High school. Nothing special, but things I am proud of .

lol I really don't care much for the comic. It just hit me while watching the movie that weapons might be a good way to both protect my country and have some privacy. I really wanted to go into politics, but I hate the lack of privacy.
