calculate the zero point energy of a system consisting of a mass of gm connected to a fixed point by a spring which is stretched 1cm by a force 1000 dynes the particle being constrained to move only along x axis

Normalize the function Ψ = e^-r

Consider an object projected straight upward from z=0 with an initial speed of u. Assume that the object is subjected to a linear drag force of the form D=-mKv

a)From the first principle show that t=1/K In(g+Ku/g+Kv) and use this result to find the time taken to reach the maximum height

b)Find the expression for the speed v as a function of time and find the limiting speed

an electron has a speed of 500m/s accurate to 0.0001% with what fundamental accuracy can we locate the position of the electron?

a mechanical oscilator has initial energy Enot= 50j having a damping coefficient b=1s. Calculate the time required to decrease to E= Enot/e

n a jump spike, Mark Angel slams the volleyball from a height of 2.3 m with a speed of 18 m/s at 24° below the horizontal. How far on the opposite side will the ball land?

If A, B and C are Hermitian operators, determine if the following combinations are Hermitian: 1 A + B 2 1 2i [A, B] 3 (ABC − CBA) 4 A 2 + B 2 + C 2 5 (A + iB) 

A nucleus has a radius of 4 Fermis. Use the uncertainty principle to estimate the kinetic energy for a neutron localized inside the nucleus. Do the same for an electron.
