a) Calculate the expected return, variance of each stock, and the covariance between the two stocks.
b) If the weights of both stocks are 55% in A and 45% in B, respectively, what are the expected return and variance of the sum of these two stocks?

In The Expanse series of science
fiction novels people live in tunnels in the dwarf planet Ceres.
The planet has been given a spin, so that, according to the novels,
it has a “gravity” of 0.3 g. Assume that this is the value in
tunnels close to the surface at the equator.
i) what is the period of rotation?
ii) what is the value of the “gravity” in a tunnel that is near the
surface but half way between the equator and one of the
poles?
no ceres. is the name of the fictional planet. .

1. Two large fixed parallel planes are 12mm apart. The space
between the surfaces is
filled with oil viscosity 0.972 N.s/m2
. A flat thin plate 0.25m2
area moves through the
oil at a velocity of 0.3 m/s. Calculate the drag force:
i. When the plate is equidistant from both the planes, and
ii. When the thin plate is at a distance of 4 mm from one of the
plane surfaces.

A quality mixture of water is contained in a piston cylinder system at a pressure of 3 bar. The initial volume of the system is 3 m3, and saturated liquid occupies 0.3 m3. Heat is added to the system and the volume is allowed to triple before a stop is reached. The final state of the system is at pressure of 30 bar. If the external pressure is 1 bar determine the followng: (a) The amount of heat added to the system; and (b) the amound of work performed by the system.

bending moment of 4 kN m is found to cause elastic failure of a
solid circular shaft. An exactly similar shaft is now subjected to
a torque T. Determine the value of T which will cause failure of
the shaft according to the following theories:
(a) Maximum principal stress;
(b) Maximum principal strain;
(c) Maximum shear strain energy. ?= 0.3.)
Which of these values would you expect to be the most reliable and
why?

I am playing pool and i hit a trick shot. I hit the ball at an angle 55 degrees. with a force of 10 newtons for .4seconds. The ball ihas a radius of 0.05m and a mass of .150kg. and the coeeficient of kinetic friction is 0.3.
1) determine the initial linear and angular velocity after i hit the ball? determine the distance the ball travels after it it and before it goes back? Determine the final velocity? answer all.
