A space station is located in a gravity-free region of
space. It consists of a large diameter, hollow thin-walled cylinder
which is rotating freely about its axis. It is spinning at a speed
such that the apparent gravity on the inner surface is the same as
that on earth. The cylinder is of radius r and mass M. (a) What is
the minimum total work which had to be done to get the cylinder
spinning up to speed. (b) Radial...
Ampère's law in free space may be written as ∮ ? . ?? = ???
a) Write the equation in words, giving the meaning of each
parameter.
b) Starting with the equation above obtain an expression for the
law in differential form.
c) A long wire P carries a current ?. Use the law to show that
the magnetic field at a radial distance r from the wire is ? = ???

Consider the function
f : [0,1]→R defined by (f(x) =0 if x = 0) and (f(x)=1 if 0
< x≤1)
(i)Compute L(f)
andU(f).
(ii) Is f Riemann
integrable on [0,1]?
Does a free good mean any good I get for free? What if I was
fishing with a hand-made fishing net and caught a fish. Is that
considered a free good? I didn't have to pay for it and I didn't
use anything that I had bought. The Native Americans used to find
all their food and water and didn't pay for it. Were they free?
What makes a good "free" in economics? Can you think of a good that...
Get In Shape, Inc. just came up with a revolutionary new way to
get in shape without exercising. The current dividend is $3.00 per
share. Analysts are predicting 30% growth in the stock of GIS for
the next three years, then after that, growth is expected to level
off at 6%. The rate expected in the marketplace for stock such as
GIS is 8%.
What is the current value of a share of Get In Shape, Inc.?

. Explain the process of translation. Be sure to include (these
are in no particular order): mRNA, ribosomes, A site, P site, E
site, where peptide bonds occur, codon, anti-codon, stop codon,
start codon, aminoacyl tRNA synthetase, tRNA, genetic code,
initiation, elongation, termination, where the process takes place,
and what is formed
Let V = 20x2yz - 10z2 V in free space, (a) Determine the
equations of the equipotential surfaces on which V = 0 and 60 V.
(b) Assume these are conducting surfaces and find the surface
charge density at that point on the V = 60-V surface where x=2 and
z= 1. It is known that 0 V 60 V is the field-containing region, (c)
Give the unit vector at this point that is normal to the conducting
surface and...
The magnetic flux density in a region of free space is given by
B = −x2 ax + 2y3 ay − 2z az T. Find the total
force on the rectangular loop shown which lies in the plane y = 0
and is bounded by x = 1, x = 3, Z= 2, and Z= 5, all dimensions in
cm. The current is 30 ampere in anticlockwise direction.
