1. Velocity of a rocket in the earth moon system

Hi all! I've just finished writing a program in python that determines the position of a rocket in the earth moon system. Initially it is in circular orbit around the earth and then it is given a velocity boost at some point in it's orbit to make it travel to the moon. I started all 3 bodies...

4. Problem with stokes' theorem

Homework Statement Let: \vec{F}(x,y,z) = (2z^{2},6x,0), and S be the square: 0\leq x\leq1, 0\leq y\leq1, z=1. a) Evaluate the surface integral (directly): \int\int_{S}(curl \vec{F})\cdot\vec{n} dA b) Apply Stokes' Theorem and determine the integral by evaluating the corresponding...
5. Signal to noise ratio/CCD saturation problem

Homework Statement A 4m telescope has a 16bit controllr with a gain of 1 and must detect faint stars(M>15) without saturating the bright stars(M=8-10). (i) What is the max no of photo-electrons that can be registered before saturating the CCD? (ii) The zero point of the system is...
6. Infinite potential well/eigenfunction problem!

Homework Statement Consider a particle of mass, m inside the potential: V(x) = 0 for 0<x<L and infinite Otherwise (i) Write down the normalised ground state and first excited state energy eigenfunctions? (ii) Use the ground state wave function to calculate the expectation value of the...
