I really need help as I have a test tomorrow and am having trouble with these problems. I have attached the questions and my work in the picture below. http://img79.imageshack.us/img79/9886/scan0001po5.th.gif Both answers are wrong. Can somebody tell me what I am doing wrong and if my...

i got it Thank you.

can you tell me what I'm doing wrong? cause I understand that the object is in equilibrium.

A mass of 10 kg is suspended from a ceiling by two cords that make angles of 30 and 45 degrees with the ceiling. Find the tension in each of the cords. This is how I set up my diagram. http://img205.imageshack.us/img205/1941/66920817mh7.th.jpg I used the sine to try to find t1, but it...

I'm sorry I don't understand. It's only my third day of calculus class. I don't understand what I am calculating?

I am totally lost on this problem and I don't know where to begin. If a and b are unit vectors that make an angle of 60 degrees with each other, calculate l 3a - 5b l the and and b have a carat of top of them Can someone help me get started?

I'm having trouble starting off with these equations: sinx(sin x + 1) = 0 I can solve sin x + 1 = Sin x = -1 x = -90 but then I don't know how to find all the solutions. Can someone please explain it to me. Thanks.

Hey guys! Well I was reading through this thread and found the posts quite interesting. I have a question for you all, I am planning to go into Electrical Engineering and in Ontario there a few school that also offer a program called Electrical Engineering and Management. I have always been...

The questions is arranged like this: 1.00 mol of oxygen molecules ? oxygen molecules I know an oxygen molecule is 02, so would it be 2 oxygen molecules? It's my first day learning moles, so I'm very lost about the 1.00 mol.

What is this chemical formula called P(4)? *the 4 is the subscript would it be tetraphosphorus? and also chemical formulas like H(2), Br(2), and I(2) just called hydrogen, bromine and iodine? *numbers are subscripts

I have Fg = 0.75 N, so that would be the work done against gravity, right? So how would I use that to find the force of friction (air resistence in this case, since the rocket is thrust upward)

I have to find the force of friction against a rocket that we launched at school. How would I do that? I know coefficient = Friction/Fn I only have Fn, how do I find the frinction? I'm really lost :(

Ok this is a veryyyyyyyy simple question. d= vt + at^2/2 (motion equation) I want to find a (acceleration) 2d -vt/t^2 = a is this the right way?

Thanks! That was very help full :) But now I'm worried about my admission into a good university. Do you guys think I have the potential to be a doctor judging on my marks? Basically do you think I'm smart enough? lol

I'm hoping that I can get some honest answers here. I'll start off by saying that I wanted to be a doctor since I was very small, and that it is like a dream job for me. I have a passion for biology and health. But the only thing standing in my way is grades. I am not a bad student but I'm not a...
