Verilog Code Help [closed] Sorry to bother anyone but I figured it out on my own.

Homework Statement Comparing the hydrogen atom orbitals to an infinite square well. a.) For the hydrogen atom, what is the energy difference between the ground state and the next energy level? b.) Now 'tune' an infinite square well holding a single electron so that it has the same energy...

Homework Statement The NIF will use extremely powerful lasers to attempt to implode a D-T target and thus initiate nuclear fusion. One pulse of the lasers will only last for 1 nanosecond, but the total energy is expected to hit 1.8 megajoules. The wavelength is in the near ultraviolet, 350 nm...

For b2, you can think of that as b2*x0. So when you take the integral of that, you would end up with b2*x1. Other than that, everything else looks correct.

That is almost correct except A/(b-a) should be squared as well and then all of that will be equal to one. Then you should do each integral then just solve for A.

You have the right idea but the two integrals added together should be equal to one I do believe. Also be sure to square the A/(b-a) on the second integral.

Yes, that is still omega.

Try using this equation for velocity: v=\omega/k

Homework Statement A heat engine operating between 78.5oC and 204oC achieves 20.6% of the maximum possible efficiency. What energy input will enable the engine to perform 10.2 kJ of work? The only help I need with this is exactly what equation(s) to use. I would think thermal efficiency...

EDIT: Nevermind, I figured it out.

Force of a Tank Hatch in terms of Pressure Homework Statement The tank shown in the figure below is filled with water to a depth of H1 = 1.88 m. http://educog.com/res/brookscole/serway/Physics_for_Scientists_and_Engineers_6ed/Chap14/graphics/serb1514.gif At the bottom of one of the side...

Are 2 of your accelerations negative? If not, then I believe this is where you are making the mistake. For example, if you are going from 40 m/s to 20 m/s in 5s, this will have a negative acceleration since you are decreasing in velocity.

Homework Statement A 850 kg car is traveling west at 25.0 m/s when it collides with a 1050 kg car that was initially traveling north at 10.5 m/s. The cars lock together, and eventually skid to a stop. What is the velocity of the cars immediately after the collision? Homework Equations...

Oh wow. That was really simple. Thanks for the help.

Homework Statement Gayle runs at a speed of 4.23 m/s and dives on a sled, which is initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.03 m, her brother, who is initially at rest, hops on her back and together they continue down...
