I am a physics major at Wabash College. I am going to graduate in the spring with a BS in physics, but I have no direction for where to go afterwards. I enjoy physics, looking at the rules and structure of the universe and figuring out how it works. I would, ideally, like a job where I can be a...
Homework Statement
In my lab we are doing Franck Hurtz experiment with heated mercury and electron beams. We already took data but i need a little help. I have the locations of the minimums A B C D and E, and each point has it's own uncertainty. a b c d and e. What i needed to find was the...
While you can't ignore friction on the ramp, you could consider the ball with coefficient of rolling friction of .1 to be a block sliding with coefficient of sliding friction of .1 also. That doesn't change the physics or calculations involved unless you get very specific. But I am sure that is...
The general kinematics equation can be manipulated to find what you are looking for.
x_f = x_i + v_i t + \frac{1}{2} a t^2
Since the problem doesn't state that there is an initial velocity it is safe to assume that it is 0.
Things to keep in mind:
the ball doesn't lose any velocity on...
The only thing I see that you need to solve the problem is the initial height or distance up the first ramp of the ball. Follow through on your plan and see what you get.
Homework Statement
There is a particle in an infinite square well and the normalized wave function is divided into 3 parts. Psi = A between 0< x < L/3, B where L/3< x < 2L/3, and C from 2L/3 < x < L. I have to prove that the decomposition into psin yields a specific cn.
