Tin (Sn) metal is a superconductor with a transition temperature
of 3.7 K. Its properties are well described by the BCS theory.
a. What is the zero temperature energy gap (in eV, not J) of
Sn?
b. The energy gap is the minimum energy required to break apart
the Cooper pairs in a superconductor. If the breaking is done by
photons what is the longest wavelength photons that can break the
pairs? What is the frequency of those photons? 1...

What are the factors in determining your takeoff critical field
length for a certain runway? If after doing initial calculations
you find the runway is too short, what might you be able to do as
the pilot in command to be legal for takeoff?
Compare and contrast the longitudinal stability of a
conventional aircraft in two conditions: forward CG and aft CG?
Discuss control forces and aircraft responses from trimmed
condition if you pulled back on the stick and let...
The ability of unsaturated field soils to retain water is
critical to the soils field capacity. A team of engineers
investigated the water retention properties of soil cores
comprising silt loam. At a given pressure the water content of the
soil was determined to be approximately normally distributed with
mean 0.27 and standard deviation 0.04.
i. What is the probability that the water content is less than
0.30?
ii. What is the probability that the water content is between 0.23...
1. What are the factors in determining your takeoff critical
field length for a certain runway? If after doing initial
calculations you find the runway is too short, what might you be
able to do as the pilot in command to be legal for takeoff?
In TLC, the polarity of the different compounds to be analyzed
is highly critical. Which one of the following statements is true?
(Check all that apply)
1 The less polar components of the mixture to be analyzed will
be less attracted to the stationary phase and therefore move
further up the plate.
2. Any solvent mixture can be used to separate any compound
mixture with TLC.
3. The more polar components of the unknown mixture move faster
up the plate...
