Hey. I have to create a program in C++ to calculate the number of prime numbers up to a specified number. I also have to print out the first and last 5, but I'll cross that bridge when I come to it.
I can do this fine with integers, but we have to do it where each slot in an array represents...
I posted it here as I'm a college freshman in engineering. And as this is a classical mechanics question it seems like the right board.
Anyway, I don't have a textbook and I can't find the relevant equation on the internet.
Also it says it starts to move, so I take that to mean it started from...
Homework Statement
A particle moves along a circular path of radius 6 m, with constant linear acceleration of 1 m/s/s. Determine its total acceleration after 2 seconds.
Homework Equations
Can't find any. That's why I'm here.
The Attempt at a Solution
I assume there's some...
Homework Statement
Heating a .8 kg disk of iron from 20 C to 400 C, but the specific heat capacity changes from 456 at 20 C, to 615 at 400 C. It hints that I'm supposed to find the average to solve the equation.
Homework Equations
E = mC(dT)

I have a...
Homework Statement
I have 2 infinitely long parallel wires each carrying a charge of 1 amp in the same direction, and I have to find the magnetic field at a specific point in between them, and I know the distance to it from each of them.
Homework Equations
This is what I'd like to know...
Well, this is just the first part of the question.
Oh yeah, reflections from more than one surface. That's a lot of help actually. Thanks.
I'd ask for more hints, but I have to go hand it in now.
Homework Statement
A glass-plate of 350 nm thickness is free standing in space. At the angle of 75 degrees, relative to the glass-plate plane, a white light point-source is placed. The diffraction (probably a typo, and should really be refraction) index of the glass is 1.33. On the same side...
