If n1<n2 and
n3<n2, which of the following statements
are true when it comes to finding out if you have destructive
interference of the reflected rays?
You do need to know if n1 is bigger or smaller than
n3.
You cannot make any calculations unless you know the numerical
value of n3.
You cannot make any calculations unless you know the numerical
value of n2.
The reflected ray from the interface between medium 1 and medium 2
will undergo a...

isA) 7 percent.B) 2.5 percent.C) 5 percent.D) 3 percent.E) -3 percent.
2. The growth rate of a population of bacteria is
directly proportional to the population p(t) (measured in millions)
at time t (measured in hours).
(a) Model this situation using a differential
equation.
(b) Find the general solution to the differential
equation.
(c) If the number of bacteria in the culture grew from
p(0) = 200 to p(24) = 800 in 24 hours, what was the population
after the first 12 hours?
3. Find the particular solution y(x) to the...
Suppose that the economy’s production function is Y =
K1/2 (AN)1/2 , that the saving rate, s is
equal to 16%, and that the rate of depreciation, ?, is equal to
10%. Suppose further that the number of workers grows at
2% per year and that the rate of technological progress is 4% per
year.
Find the steady values of the variables listed in (i) through
(v).
The capital stock per effective worker.
Output per effective worker.
The growth rate of...
