Consider Wein bridge oscillator. If R1 = 3R2 and C2 = 4C1, find
the expression for cutoff
frequency. What will be the value of β and the required gain?
A. Consider two concentric spherical structures of radius r1 and
r2 such that r1 < r2 and full load Q and -2Q respectively.
Calculate the magnitude of the field on ́ectrico in all three
regions, i.e. within the smaller sphere, between the spheres and
outside the sphere of the larger radius.
Where does the electric field point to for this system?
(no matter what material these concentric spherical are made
of)
B. Two cylindrical coaxial shells with radius r1 and...
Let N=15,000 and a double sampling plan with n1=40, n2= 80,
c1=1, c2=2, r1=r2=c2+1. The lotOs fraction defective is 2%. Compute
the probability of accepting lot in the first sample.
An
oscillator is describe by the expression x(t) = .25 m cos[(1.3
rad/s)t - 1.8 rad].
A) what is its period of oscillation?
B) what is its velocity at t = 1.9 seconds?
You are looking to find regions of statistically significant
differential expression, you consider two distinct ways of looking
at the problem. In the first, you look at all windows of length 10
kb. In the second, you consider only the 20,000 annotated protein
coding genes. Give the pros and cons of these two approaches, being
sure to comment on how the desired statistical cutoff is influenced
by testing multiple regions. (Recall that the human genome is 3.0
×109 bp.)
Consider the following relations:
R1 = {(a, b) ∈
R2 ∣ a > b}, the
greater than relation
R2 = {(a, b) ∈
R2 ∣ a ≥ b}, the
greater than or equal to relation
R3 = {(a, b) ∈
R2 ∣ a < b}, the
less than relation
R4 = {(a, b) ∈
R2 ∣ a ≤ b}, the less
than or equal to relation
R5 = {(a, b) ∈
R2 ∣ a = b}, the
equal to relation...
You wire a real battery to a R1 = 42 Ω resistor and find that
the output voltage between its terminals is V1 = 8.6 V. You
disconnect it from the first resistor, wire it to a R2 = 720 Ω
resistor, and find that its output voltage is V2 = 9.7 V. (a)
Determine the current through each resistor. I1 = I2= (b) Find the
internal resistance and emf of the battery. r = Ω e m f =...
1. Consider an electron in a 1D harmonic oscillator potential.
Suppose the electron is in a state which is an equal mix of the
ground state and the first-excited state.
a) Write the time-dependent state in Dirac notation.
b) Calculate 〈x〉. Calculate 〈p〉 using raising and
lower operators.
c) Graph 〈x〉 as a function of time.
