Somebody has a theory predicting that when a laser device with frequency f moves towards an observer at speed V, the observer measures a frequency f’= f/(1-V/c), while if the device is at rest and the observer moves towards it, he measures f’=f(1+V/c). In both cases, f’>f, which seems reasonable.
Using the Special theory of Relativity heuristically, discuss whether this theory can be correct or not.

A company is considering the purchase of an industrial laser for
$150,000. The device has a useful life of five years and a salvage
(market) value of $30,000 at the end of those five years. The
before-tax cash flow is estimated to be $45,000 per year. The laser
would be depreciated using MACRS with a recovery period of three
years. If the effective income tax is 25% and the after-tax MARR is
15%, use the PW method on an after-tax...

Two lasers are sent through the same double-slit device. A blue
laser has a wavelength of
430nm, and a red laser has a wavelength of 645nm. The spacing of
the slits is 2mm, and the
distance to the screen is 1.0m.
A) Sketch what the blue laser will look like on the screen; give
a distance scale.
B) On your diagram, find a point at which both the red light and
blue light will be at a bright
fringe. Show...
a) A population of horses has an allele frequency of F(A)=0.08 and F(a)=0.2. The relative fitness of the population is 0.616.
a) A population of horses has an allele frequency of F(A)=0.08 and F(a)=0.2. The relative fitness of the population is 0.616. If sAA=0.4 sAa=0.4 saa=0. what is the expected allele frequency of aa homozygote in next generation?
b) A zoologist is studying a new species that finds the allele frequency is F(F)=0.58 and F(f)=0.42 if w11=w12=.78 and w22=1 what is Deltap?

An object with a size r0 has a Reynolds number of 4
when it moves through a fluid at a speed v0. What is the
Reynolds number for an object with a size 2r0 moving
through the same fluid at a speed v0/2?
The answer is 4. Please explain why and what
concepts were used to get to this answer!!!

A device has two states: ON and OFF. When it works normally, it
spends a random time in the ON state, then a random time in the OFF
state, then again in the ON state, and so on. However, when
switched from OFF to ON, the device fails with probability 0.05 and
a replacement process is triggered immediately. Once a new device
is in place, it is turned ON. Suppose that the average durations in
the ON and OFF states...
