W represent the wingspan of an airplane and V represents the velocity which are 2 random variables.
W has a normal distribution with mean 10 and standard deviation 4.
Also V = 0.5.W + U, where U is a random variable (we might call error). Assume that U has a standard normal distribution and is independent of W. Derive each element of the variance-covariance matrix for W and V using properties of Variance and Covariance.

A series RLC circuit connected to a 24-V AC source has a current of 150 mA when the AC source is set to 85 Hz. The voltage on the capacitor is measured to be 36 V. When the frequency of the source is adjusted in any way the current decreases. Calculate the values of R L, and C.

In P4, the frequency of the AC source is increased until the voltage on the capacitor has dropped to 12 V. Calculate the voltage on the inductor at this frequency

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 = V

a)Does the vibrational frequency of an O-H bond depend on whether it is horizontal or vertical at the surface of the Earth? Suppose that a harmonic oscillator of mass m is held vertically, so that it experiences a perturbation V(x)=mgx, where g is the acceleration of free fall. Calculate the first order correction to the energy of the ground state.

b) Repeat the previous exercise to find the change in excitation energy from v=1 to v=2 in the presence of the perturbation.

The nose of an ultralight plane is pointed south, and its airspeed indicator shows 39m/s . The plane is in a 12m/s wind blowing toward the southwest relative to the earth.

Question A:

Letting x be east and y be north, find the components of v? P/E (the velocity of the plane relative to the earth).

Question B:

Find the magnitude of v? P/E.

Question C:

Find the direction of v? P/E.

Any help is appreciated!

Does the weighting function in the prospect theory magnify the importance of very low and very high probabilities? Why and how?

Prospect Theory offers an alternative framework to making decisions by expected utility maximization. It allows for these realistic behaviors exhibited by investors:
I) Having better prospects if seen next to an irrelevant, slightly flawed, alternative

II) Measuring success with respect to an (arbitrary) reference point

III) Loss aversion

IV) Tolerance for ambiguity when faced with the prospect of extraordinary gains

V) Stronger reactions to losses than to gains of the same magnitude

a. II, III and V

b. I and IV

c. I and II

d. III, IV and V

e. II and V
