A propane tank with 75 gallons of liquid propane is at 50 F in a sealed tank. The tank develops a significant leak and propane escapes and vaporizes in a short period of time. To solve this problem you must use the propane tables not the common liquid properties.

What is the temperature near the hole in the propane tank due to the escaping propane in Fahrenheit to three significant digits? .   Include a minus sign if appropriate.

How many Btus of energy are needed to vaporize the entire 75 gallons of liquid propane? . Give your answer to three significant digits in Btus.

Eyeglasses are often coated with an anti-reflecting coating to reduce glare in the visible part of the spectrum. Consider a 95.0-nm-thick coating applied to the lens, where we wish to reduce the glare of the blue end of the spectrum with wavelengths near 450 nm.

a) If the coating’s index of refraction is smaller than that of the lens, what index of refraction for the anti-reflection coating is needed for the thinnest film possible?

b) If the coating’s index of refraction is greater than that of the lens, what index of refraction for the anti-reflection coating is desired for an m = 1 destructive interference scenario?

Halloween is just around the corner, but it will be hard for the kids to go out for trick-or-treats or adults to go for Halloween night party because of the COVID-19 pandemic. According to the National Retail Federation (NRF) is U.S., in 2019, Americans planned to spend a near-record $8.8 billion on Halloween, the third most expensive Halloween postrecession.
a) What can you expect about the Halloween expenditures this year? Will it go up or down or remain the same? Why?
b) What other concepts from economics you can apply to Halloween? State and briefly explain all.

Q. 1: The far distance a person can see an object is at a distance of 50 cm from the eye but she wants to see an object at infinity. What types of lens is required to make her vision correction? Calculate the optical power of her lens.

Q 2: The near point a person can see an object is at a distance of 50 cm from the eye but he wants to see object at the least distance of distinct vision. What types of lens is required for him to correct his vision? Calculate the optical power of his lens.

94. Choose the false statement:

A. The actions of the muscles required for inspiration serve to increase the volume of the thoracic cavity; as a result, alveolar pressure decreases relative to atmospheric pressure.

B. Cholecystokinin is released by enteroendocrine cells in response to fat in the gut; this hormone triggers the release of digestive juices from stomach, increases gastric (stomach) motility and the rate of stomach emptying.

C. Chylomicrons carry dietary fats absorbed across the gut; these are manufactured by intestinal epithelial cells, are then transferred to the lymphatic circulation and are finally delivered into the blood venous circulation near the heart.

let R be a region bounded by x = 0 and x =1 and y = 0 and y = 1. Suppose the density is given by 1/y+1.Notice that R is denser near the x axis. As a result we might expect the centre of mass to be below the geometric center(1/2,1/2). Also since the density does not depend on x we do expect moment of inertia about the x axis to be 1/2. verify the moment of inertia about x is 1/2 and compute the value of the moment of inertia about the y axis

ORGANIZATIONAL BEHAVIOR

1. After a century-long ‘discovery’ about motivation, have we reached the promised land of healthy, productive, and satisfied employees? What does your own experience during the lockdown period tell you? Which theoretical approach did you find particularly helpful in thinking about your own motivation? Discuss.

2. In your opinion, what did the pandemic teach organizational leaders? Which of the leadership theories will remain relevant in the near future? And why? Or do we now need a new theory of leadership? Discuss.

1. For each of the following situations, indicate the amount of income, if any, that would be taxable in the year 2020:

A. R found a box while jogging near her home. In the box was $100,000. R reported the find to the police, but because the owner could be found, R was allowed to keep the money.

B. W purchased 10 acres of land for $100,000. Shortly after the purchase it was discovered that oil was present beneath the ground. The value of the land immediately increased to $5,000,000.

C. E borrowed $50,000 from a bank using his home as collateral for the loan. The home was worth $900,000.

A company just purchased a piece of equipment for $650,000. The economic reality is that the asset has an estimated useful life of ten years and will be worth $75,000 at the end of its useful life. Straight-line is the appropriate depreciation method.

1. Using excel, compute the depreciation schedule for this asset. How much depreciation expense will be taken each year? What will the asset's book value be at the end of Year 6?

2. If the company wanted to increase its earnings in the near term, how could it accomplish this by using their estimate of:

A) Useful life?

B) Salvage value?
