Consider a MachZehnder interferometer where in one arm we place a filter with a transmission coefficient f << 1. The system is set up such that at one detector site we have constructive interference and at the other side we have destructive interference. Demonstrate that the expected number of dete...
Please help answer this question. It requires you to give proof that two definitions of angular momentum are equal.

1. Consider a real scalar field phi with interaction Largrangian L_int = (p/(3!))phi^3. What is the mass dimension of u? Evaluate the leading udependent contributions to the following equation: (see attached file)
In physics one often needs to sum divergent series. Here we give a simple example of how one can estimate the limit of x to infinity of a function f(x) given by its Taylor expansion around x = 0 when its radius of convergence is only 1.
Provided is a list of variable names. Determine what is wrong (if anything) with each variable name and how to fix it.

In many problems in mathematical physics, particularly in connection with Legendre polynomials (Chapter 12), we encounter products of the odd positive integers and products of the even positive integers. For convenience, these are given special labels as double factorials:
1*3*5***(2n + 1) = (2n ...
How much time is required before a 10 mCi sample of 99mTc (T1/2=6.0 hours) and a 25 mCi sample of 113m In (T1/2=1.7 hours) possess equal activities? Please see the attach file.
Two loudspeakers are placed side by side a distance d=4.00m apart. A listener observes maximum constructive interference while standing in front of the loudspeakers, equidistant from both of them. The distance from the listener to the point halfway between the speakers is l=5.00m.

The pendulum shown in the figure (see attachment) consists of a thin disk and two slender rods. The disk has a mass of 2 kg, the longer rod AB has a mass of 6.5 kg and the shorter rod CD has a mass of 2.5 kg. Determine the moment of inertia of the pendulum about an axis perpendicular to the page pas...
Three uniform meter sticks, each of mass m, are placed on the floor as follows: stick 1 lies along the y axis from y = 0.350 m to y = 1.35 m, stick 2 lies along the x axis from x = 0.130 m to x = 1.13 m, stick 3 lies along the x axis from x = 1.41 m to x = 2.41 m. Calculate the location of the cente...
As a result of a chemical spill, benzene is evaporating at the rate of 1 gram per minute into a room that is 6 m * 6 m * 3 m in size and has a ventilation of 10 m3/min.
a Compute the steady state concentration of benzene in the room.
b Assuming the air in the room is initially free of benzene,...
The 0.5 lb weight is suspended from a rigid frame as shown in the attached diagram. Pin A at the end of the rotating arm OA engages a slot in the frame, causing the frame to oscillate in the vertical direction. The arm is accelerated uniformly from rest at t = 0 and θ = 0 at the ω.(dot) = 100 rad/...

A large bell is hung from a wooden beam so it can swing back and forth with negligible friction. The center of mass of the bell is 0.50m below the pivot, the bell has mass 38.0kg , and the moment of inertia of the bell about an axis at the pivot is 20.0kg*m^2. The clapper is a small, 1.8kg mass at...
