This was part of a homework assignment for my Physics class. I was wondering if anyone could please help me solve this by providing at least some background guidance:

(Fx is F sub x and Fy is F sub y)

The x and y components of a force are Fx = 12N and Fy = -15N, respectively. Determine the magnitude and direction of F.

Thanks! ^_^

I need to know how to add and subtract measurements. I left my book at school, and I can't remember at the top of my head.

For example: 6.20 x 10 to the 5th power(sorry, I don't know how to type exponents) mm + 7.20 x 10 to the 6th power mm(No, this isn't a homework problem I want you to do for me. I just need to know the steps on how to do it.)

If you can help in any way, please do share your knowledge. It'd be greatly appreciated!!

How did this:

(cosθ sinθ + (1 + sinθ) cosθ) / (cosθ cosθ - (1 + sinθ) sinθ)

become this:

(cosθ(1 + 2sinθ)) / (1 - 2sin^2θ - sinθ) ??

I have this chemistry project where i have to design the square in the periodic table of elements for Rubidium (Rb). I cant name what it is on the square, but have to give clues with the design of the square. I've done research and found that it is silvery white liquid at room temperature. but i don't think I can work with much with this, especially if i dont put the name on it!! Can someone tell me a defining property or key feature of this element that I can incorporate into the design???

Some postings in other groups insist that during certain periods of acceleration during his trip a traveller insists that his twin sister is physically ageing at faster or slower rates than she was before he commenced his trip on the basis that this is what he determines on the basis of his calculations based on the Lorentz equations.

I am trying to find out if this concept is 'conventional wisdom' in the scientific world?

Ninette wants to sweeten her iced tea. She looks in the restaurant's sugar dish and sees regular white granulated sugar and a packet of natural sugar. She opens each and sees that the natural sugar has very large crystals, much larger than the granulated sugar. Which sugar would be more likely to dissolve without Ninette having to stir the tea? Explain.
