Is it convergent, divergent and what test if any did you use to get it.

What is the oxidation number of Sulfur in SO (sub3)(super 2-)?
I'm thinking there are 3 oxygens with a -2 charge, therefore we have -6 charge for oxygens which means a 6 charge for sulfur?
thanks in advance

Ok, I have this really simple lab but its just not working out and I dont know why. It seems complicated but its not. If you could read it out and help me it would be GREATLY appreciated. I dont get where Im going wrong. (See details if I run out of space.) The goal is to find the acceleration due to gravity. (9.8m/s^2)

We dropped a plum bob and as it dropped it marked in a piece of wax paper ever 1/30 seconds. We circled EVERY OTHER DOT. We then measured the distance from each circled dot to the next starting at dot one. (0 to dot two, dot two to dot four, dot four to dot six, etc. Aka, every other dot.) The time between each dot is 1/60 of a second. (its really 1/30, but we are measuring every other dot so its 1/60) My lab sheet tells me to make a displacement vs. time graph but Im not exactly sure why. Im trying to find acceleration which would be the slope of a Velocity/Time graph. So anyway, here are the displacements I got from measuring the dots mentioned before:

Hello I need help for spring problem
Here is the question
Two large crates, with masses 640kg and 490kg, are connected by a stiff, massless spring (k=8.1kN/m) and propelled along an essentially frictionless, level factory floor by a force applied horizontally to the more massive crate.
If the spring compresses 5.1cm from its equilibrium length, what is the applied force?

I have looked on the Human Genome Project website, and yet, I am unable to find a link anywhere where I can download the entire nitrogen base sequence of a chromosome (just plainly and simply laid out in terms of ATGC). Do you know where I can go? Preferrably, this would be an online reference that I could download, as apposed to a book, because my end goal is to get all of the information in a manipulatable text or word processor document.
