The angle between the two forces is 45 degrees... I'm to find the magnitude AND the direction of the resultant of those two forces. I have the answer, but I need to see how it's found.

I know this is a simpler problem because I took a year of college physics because I'm a premed, but it was a while ago and I've moved on in and almost forgotten it. I have some major brushing up to do before grad exams, but can anyone help me solve this?

Apparently its still a closely guarded secret, I mean in today's day and age, how hard could it be to find out by lab tests?

Its probably not love.

I read in wikipedia that trans fat are bad for health.
http://en.wikipedia.org/wiki/Trans_fat

I reckon that I should avoid all process food and commercially available food which contained/used those type of fat/oil/shortening.

I worked in a fish-n-chip shop and see that the fat they used is transported in carton in solid form but they are so-called palm oil.

Are they hydrogenated vegetable oil?
Is that white solid fat commercial Palmitic acid (hexadecanoic acid) bad?

If some merchants/manufacturers only vaguely list [vegetable oil] or [palm oil], that would be so difficult to tell. (shouldn't I be sceptic/careful?)

******
Along [shortening] & [partially hydrogenated vegetable oil]
Any other labelling to watch out for? ( trans fatty acid)

how many grams of sodium chloride can be produced from 10.9 g of NaOH?
I have already solved this problem I just want to check my solution against others. So please don't tell me I am a cheater or lazy because you don't get credit for a problem like this without showing work, I just want to compare answers no need to show me your work. THANKS

If it's true that all people originated from Africa or the Middle East and that skin pigment developed due to geographical location, i.e. black people originating from Africa are black due to the enviroment there and white people originating from North Europe are white due to enviroment there and all inbetween etc, then how can the pigment of humanities skin be traced through evolution? Is there evidence to this or is it like most things in science that can't be proven absolute and it's pretty much just theory?

Especially in astronomy, what we know of the universe is pretty much solely theory based on observations of our planet applied to space and astronomy but people regurgitate this information as fact without consideration or belief that it is agruable and constantly under examination and investigation.
