Mechanics of Deformable Media (Bhatia and Singh), 5.2:
Consider a long rod of elastically isotropic material of L standing vertically in a vacuum in equilibrium under the gravitational field of the earth, then:
(i) What are the boundary conditions for \sigma_{ij} on the...
Let's say a proton is confined to some diameter, d. What would be the uncertainty in the position?
In some questions they use delx as (1/2)d as the uncertainty in position. In other cases they use the entire d as the uncertainty. This is extremely confusing...
1. Question
A cubic crystal of interatomic spacing of 0.24 nm is used to select
gamma–rays of energy 100 keV from a radioactive source containing a continuum of energies. If the incident beam is normal to the crystal, at
what angle with respect to the incident beam do the 100 keV...

It's question 2.
Homework Equations
Work = U/t
E = hf
f = c/lambda
I=Q/t
The Attempt at a Solution
f = c/lambda = (3.00x10^8 m/s)/(530x10^-9 m) = 5.66x10^14 Hz
E = hf =...
Homework Statement
The question can be found on this link. It is the last question, the one with the DNA molecules. Prof said that the direction is not important, he is just looking for a magnitude.
