The 45 newton box hangs from a cord that passes over a frctionless pulley and attached to 130 newton box that is held on an incline. The answer is forty-nine degrees, but I need to show work to get credit for this problem and I do not know how to get to that answer even when my teacher gave all the students the answer. The coefficient of friction is .620.

why if we want to know if a number is divisible by 3 we add it's digits and if the sum of them is divisible by 3, the whole number will be too? for example 351 the sum of its digits is 9 so we say the whole number is divisible by 3.I mean I want a prove or reason of why we add them to know thought it is division .please help me please or I'll get mad of thinking.

there isnt an answer i know, scientists have proven how the galaxies have been formed etc etc, (really interesting =)) but one thing they havent proven....how did it all get there in the first place? how did the big ball get there to explode and create these galaxies? iam very interested in what people think of it. Maybe we are all here for a reason...maybe we are here to find our own path on Gods creation. That it is our responsibility to make ourselves happy in life on what God has made. finding everything out for ourselves. that maybe one day we can communicate with another planet outside our solar system. what do you think?

I am thinking about starting a homework math resource....not sure how it would work, but if you had a problem a bunch of us could get together and try and solve the questions, but concentrate more on the "How" portion.

Would you like to help?

I need to charge two plates positively and negatively using a battery. How to do it? Would simply connecting the plates to the terminals do? I guess it won't. So please help. Need it for a science project.
