Physics Help Vectors So we're currently on the chapter with Vectors and we were suppose to do certain problems on this worksheet; however, I came across a problem which I have no idea how to solve. Here it is: "A traffic light is supported by two cables that are 140 degrees apart. Each cable exerts a tensile force of 150 N [Newtons] on the light. How much does the light weigh?" A step by step solution is needed, I don't just want the answer but how you got the solution. Thank you :)

Help with Economics Homework So we're talking about Production Possibilities Frontier and I have the definition of it but I don't quite understand it. Here are the directions as to what I have to do: "Directions: create a graph of the production possibilities curve for each of the table data. [b]Label the production possibilities frontier on each graph.[/b]" And this is what we have to graph. Bananas (in tons): 0, 5, 9, 15, 17, 19. Pencils (in millions): 25, 22, 16, 7, 6, 5 How do I locate where the production possibility frontier is? On an example graph it points to a specific area, but it's confusing me. Another question: Now create your own comparing two products. (Use manufactured data.) What does it mean by manufactured data?

How well will Windows 7 run I'm upgrading from Windows Vista to Windows 7 so I decided to run the Upgrade Advisor program; however, it states that I have 896 MB RAM, which is probably being used by my video card and whatnot, but I actually have 1G RAM. Call me cheap but I don't want to buy more RAM unless I really have to, this is only because I won't be using this computer after this year :D Anyways will I be able to run Windows 7 smoothly with minimal computer lag, or will I seriously need to inject steroids into my computer with RAM so that I can run programs? I usually play games, but I'm not a hardcore gamer; I won't be sipping energy drinks at 3am trying to shoot someone in the middle of the snow with my mouse, but I watch a lot of vi

SATs Tomorrow; I have a quick question! SATs are tomorrow or today or yesterday depending on where you live it's on the 7th of May! Well anyways I have a question it's dumb but I'm curious! So the SATs allow you to bring snacks for their breaks and I know exactly what to bring, but am I able to bring a bag or something to put my food in? I know you're allowed to put your snacks off the desk but would they allow me to bring a bag with my food in it as well as my needed materials? Should I just bring my backpack?

Question about Graphic Novels I made a thread about 1 month ago regarding which graphic novel I should pick to read for my AP English class; this prompted one basiler, or two I can't remember, asking me if I was serious that an AP Class would make us read graphic novels as an assignment. I know a few reasons as I've researched some pros and cons about graphic novels, but I would like more in depth details about graphic novels. So my question is: Should a class, preferably grade 7 and above, read graphic novels for an assignment; why or why not? If the teacher knew how to utilize graphic novels should they still use them as an assignment? Are graphic novels good or bad for the brain?

Confused on this math problem I have no idea how to solve this problem, the book doesn't help as much and my teacher didn't go over this type of problem with us. We're doing Exponential Growth and Decay and here is the problem: "A Certain medication is eliminated from the bloodstream at a steady rate. It decays according to the equation y=ae^-0.1625t, where t is in hours. Find the half-life of this substance." I have no idea what to do. Please help, thank you :) I don't want the answer btw, because I already have it, I just need the steps.
