In 2018, the Westgate Construction Company entered into a contract to construct a road for Santa Clara County for $10,000,000. The road was completed in 2020. Information related to the contract is as follows:

Westgate recognizes revenue over time according to percentage of completion.

3. Complete the information required below to prepare a partial balance sheet for 2018 and 2019 showing any items related to the contract. (Do not round intermediate calculations.)

3. Let P be an nxn projection matrix (which means that it satisfies P²=P and P^T=P). The goal of this problem is to show that P as a linear transformation is the orthogonal projection onto the range of P.

(a) Show that if v is in the range of P, then Pv=v.

(b) Show that if v is orthogonal to the range of P then Pv=0. (Hint: PPv lies in the range of P, hence is orthogonal to v. Study the dot product of v with PPv.)

(c) The previous parts show that P and the projection map act the same way on vectors that lie either in the range of P or the orthogonal complement of it. Why does this imply that P and the projection map agree on all vectors?

An absorption column operates at 1 atm to separate compound A from air using pure water as solvent. If the concentration of A in the inlet air stream is 900 ppm and the Henry's law constant for A in water is 1000 atm/ppm:

a) What is the equilibrium line equation? (** draw on chart and label)

If the desired outlet air is to contain 200 ppm compound A:

b) What is (L/V)min? (** draw on chart and label)

c) If the actual operating (L/V) is 1.285(L/V), what is the operating equation? (** draw on chart and label)

d) If the actual operating (L/V) is 1.285(L/V), what is the required number of ideal stages? (** draw on chart)

Consider a thin flat rectangular region that of size 4 x 2 m2 and it is electrically insulated at its four corners. (A)Solve Laplace’s equation  2 V(x,y) = 0 in the rectangular region 0 < x < 4 m and 0 < y < 2 m using the separation of variable technique subject to the following boundary conditions:
V(0,y) = 0
V(4,y) = q(y) = 50 sin (3π y / 2)
V(x,0) = 0
V(x,2) = f(x) =100 sin (π x / 4)
(B) Use the result of part (A) to find the corresponding electric field inside the region.

A nonlinear relationship between analyte concentration and intensity during a fluorescence experiment. The function becomes exponential (tails off) as higher concentrations are analyzed. How would you modify the experiment or the instrument to combat this problem? Describe two solutions.

a) What are the possible errors /uncertainties that can occur in an Incline Friction Experiment? (as detailed as possible for this part)(at least 500 words)

b) What is the Theory about the Incline Friction experiment? (as detailed as possible for this part)(At least 500 words)

1. There are safety hazards in this lab experiment.  Specifically, what are the safety hazards associated with the experimental procedure?  Be sure to clearly identify and explain why these are hazards.

The successful interpretation of Young’s double slit experiment is dependent on a complete understanding of Huygen’s principle. Explain what Huygen’s principle tells us about a wave and how it is used to demonstrate that the double slit experiment shows that light is a wave.

A binomial probability experiment is conducted with the given parameters. Use technology to find the probability of x successes in the n independent trials of the experiment. Use the Tech Help button for further assistance. n=9, p=0.2, x < 4

If I want to design an experiment related to kinetic friction, can the following proposal meet the requirement?
By varying the weight of an object and measure the stopping distance of that object.
Is this related to kinetic friction? If not, how should I change my experiment?
