I've basically just finished grade 10 physics, I didn't find it all that hard. The problem also was that me and some of my classmates felt the teacher wasn't teaching that well, which made it a little harder to understand.
Basically my questions is should I take it in grade 11, even though...
hey I've got a few questions that i would like some help with. I am new to these forums but if you could post your steps to the awnser, with an explanation that would be great.
1. Two metal sphers, one having a charge of 4 * 10^-6 C and the other having a charge of 2 * 10^-6 are 3 cm apart...

Hello fellow scienteers and mathematians :p, after talking with my computer science teacher (who I idolize ;)) I've decided to take AP Physics next year, he'd be my teacher for that course.
He wouldn't tell me what I'd be taught in that course, figures, since he's a teacher and all that jazz...
hello I am in grade 11 chemistry and I am doing a coppersulfate lab. Please help!
ok these are the lab questions. My friends and i have been stuck on it for a whole period and afterschool and I am not really sure what I am doing.
1. A hydrates MGSO4 salt, weighing 3.211g, is heated until...
I have a question, a huge one but simply it is.. A family goes on a ten hour drive, 100km an hour on highways(x) and 60km(y) an hour on city roads.
100x+60y+880, and
x+y=10
Just need a push in the right direction. Thanks in advance.
Hi, my exam is coming pretty soon and I looked at last year's exam and found numerous questions that I don't know. Could someone please check my answers listed below.
A solution of any type is different from a compound because:
(A) a compound is always coloured, solutions never are.
(B)...
Hi,
I need help on these two questions.
1.Describe the differences between the dissociation of an acid (or base) in water and the ionization of an acid (or base) in water.
2. A student working in a chemistry laboratory is given 2 bottles, each filled with 1.00L of clear and colourless...
If anyone could answer even just one of the questions below I would really appreciate it.
1. Why do cars get better gas mileage at constant speed than they do with a lot of accelerating?
2. The space arm works in weightless conditions (actually called microgravity conditions). Why must it...
Hey there.
I'm currently taking grade 11 physics, and as part of our final evaluation, we have to perform an in-class lab. We're not given the procedure, just what we have to determine and a list of apparatus. I have a general idea of what to do, but I'd just like some confirmation if what I'm...
I have an Independent Study to do in math and I'm wondering if anyone has any project ideas? Something that I can learn on my own that uses moderately difficult mathematics (from a grade 11 perspective) and can be turned into a PowerPoint presentation.
~Thanks.
I thought about doing...
Hello,
Just couple of of Physics questions. I want to make sure I got them right.
1.How much force (tension must a rope withstand if it is used to accelerate a 1700 kg car at 0.50m/s^2 on a frictionless surface.
I got:
(1700)(0.50)
F=850\frac{kgm}{s^2}
2.A 0.15kg baseball traveling...
Hello, I just want to make sure I did my problem right.
Q: A 41.0N force is applied to a 300 kg crate to make it just move. Calculate the coefficient of static friction.
My Work:
Is that right?
This question I really don't get.
Q:The driver of a car applied the brakes so hard that the...
[FONT=Comic Sans MS]This question comes from a section on "Solving Problems With Quadratic Equations." I'm having problems with this, and I can't figure out why I can't get the right answer.
I drew a digram with the information. I used the formula to find area which is a=lw. The width of...
I have a few questions I've been having troubles with, and I was hoping someone could help me out...

Ok I have two questions both i have done but not 100% sure I have done them correct. I am good with math but not so well at Trigonemetric stuff. Ok here it is.
1) Convert the following angles to radian measure, leave in simpilest rational form. 350 degrees.
Ok what i have done is this...
Hello, I just found this place and I am glad I did. :D I have a big physics project and I need to relate bicycle to physics. I am in grade 11 and I was wondering if anybody can give me some ideas/suggestions on what kind of things I can relate physics to bicycle using up to grade 11 physics...
