On average, a lightning flash on Earth transfers about 30 C is transferred across 1 GV.

Suppose that, in a single lightning flash, 27.7 C of charge is transferred through a potential difference of 2.44 GV. If all this energy could be used to accelerate a car of mass 1,427 kg car from rest, what speed would the car reach, in m/s?

NOTE: 1000 m/s is 2237 miles per hour!

Java How to Program Exercise 4.11
Explain what happens when a Java program attempts to divide one integer by another. What happens to the fractional part of the calculation? How can you avoid that outcome?

My instructor want me to do that exercise with these details and I am so confuse. I don't know where to start.
"Random number of Trips"
"Enter gallon and miles as whole numbers"
"NPG decimal number"

1) Blue Ram Brewing Company currently has no debt in its capital structure, but it is considering using some debt and reducing its outstanding equity. The firm’s unlevered beta is 1.15, and its cost of equity is 11.55%. Because the firm has no debt in its capital structure, its weighted average cost of capital (WACC) also equals 11.55%. The risk-free rate of interest (rRFrRF) is 3.5%, and the market risk premium (RPMRPM) is 7%. Blue Ram’s marginal tax rate is 25%.

Blue Ram is examining how different levels of debt will affect its costs of debt and equity, as well as its WACC. The firm has collected the financial information that follows to analyze its weighted average cost of capital (WACC). Complete the following table.

F. Pierce Products Inc. is considering changing its capital structure. F. Pierce currently has no debt and no preferred stock, but it would like to add some debt to take advantage of low interest rates and the tax shield. Its investment banker has indicated that the pre-tax cost of debt under various possible capital structures would be as follows:

F. Pierce uses the CAPM to estimate its cost of common equity, r_s and at the time of the analaysis the risk-free rate is 5%, the market risk premium is 8%, and the company's tax rate is 40%. F. Pierce estimates that its beta now (which is "unlevered" because it currently has no debt) is 1.15. Based on this information, what is the firm's optimal capital structure, and what would be the weighted average cost of capital at the optimal capital structure? Do not round intermediate calculations. Round your answers to two decimal places.

Hydrogen gas is a very useful reagent with many uses in the petroleum, food, and chemical industries. Most hydrogen exists in covalently bonded molecules, and atmospheric air contains less than 1 ppm of diatomic hydrogen. Therefore, hydrogen gas is produced on a large scale for these uses, where steam reforming with methane and electrolysis of water are two of the primary methods. The more economic reaction of steam reforming is the reverse of the reaction depicted in Carbon Monoxide and Hydrogen - Sample 1 in the Simulation.

Hydrogen has also been considered as an alternative fuel for vehicles designed to combust hydrogen and oxygen, which produces water as a product. However, concerns were raised because methane is typically used on a large scale to produce hydrogen gas. Assume that a gallon of gasoline contains 2400 g of carbon. If a gasoline engine achieves 30 miles per gallon, each mile consumes 80 g of carbon (about 107 g of methane contains 80 g of carbon). Alternatively, a hydrogen engine can achieve 80 miles per kilogram of hydrogen gas.

What is the mass of methane (CH4) needed to produce enough hydrogen gas (H2) to drive one mile using the theoretical hydrogen engine?

Your client is in big trouble. He owes $1.3 million to IRS for the year ended December 31, 2017. He won a lawsuit on June 1, 2016 in the amount of $5 million and lost almost everything in day trading. He just forgot to pay taxes on his winning of law suit. He is married and has three children-16 years, 12 years and 11 years old. He makes $3,333 per month. H had $439 in his bank account. He has two credit cards (1) Credit limit $18500, amount owed 8,592 (2) Credit limit 7,500 amount owed $6,247. He owns two cars (1) 2006 Nissan Quest, miles 85,000 (2) 2007 Maxima miles 87,000. He has clear title to these cars. He owns a house in Kingwood Texas –purchase price $217,000 date acquired 02/01/01 current value 210,000 loan balance 177,395 monthly payments $1,585. There are quite a few homes on sale in his neighborhood.

Question: what statement of laws that we can apply and discuss that laws

A German car will cost $45,000 and have fuel usage of 21mpg for the first 5 years, and decrease
by 1% thereafter to year 8. Repair cost will start at $1000 in year 1 and increase by 4% per year.
It will have a salvage value of $7000 at the end of year 8. Insurance cost will be $850 the first year,
increasing by 2% per year thereafter.
The American car will cost $35,000 and have fuel usage of 20mpg for the first 3 years, and will
decrease by 3% per year thereafter. Repair cost will be $800 in year 1, increasing by 4% per year
thereafter. Being an American, the graduate will price the pride of owning an American car at $0.4
for every 20 miles driven, increasing by 2% per year. Insurance cost will be $800 per year
increasing by 2.2% per year. The car can be sold for $5500 at the end of year 8.
If the graduate anticipates driving 150000 miles by the end of year 8 and the average interest rate
is expected to remain at 5% per year, which car is economically affordable based on present worth
analysis? Assume fuel cost will be $3 per gallon in year 1 and increase by an average of 2% per
year. Show all your workings.

1. Engineer wants to develop a model to describe the gas mileage of a sport utility vehicle. He collects the data presented in following table.

1. Identify the dependent variable and independent variables.

2. Build a multiple linear regression model to predict miles per gallon.

3. Can this model used to make predictions? Explain.

Skysong, Inc. purchased a delivery truck for $32,400 on January 1, 2019. The truck has an expected salvage value of $2,400, and is expected to be driven 100,000 miles over its estimated useful life of 8 years. Actual miles driven were 15,700 in 2019 and 12,900 in 2020.

Compute depreciation expense for 2019 and 2020 using (1) the straight-line method, (2) the units-of-activity method, and (3) the double-declining-balance method. (Round depreciable cost per unit to 2 decimal places, e.g. 0.50 and depreciation rate to 0 decimal places, e.g. 15%. Round final answers to 0 decimal places, e.g. 2,125.)

Toby wants to calculate her COGS for a fertilizing job she did last week. She used 40 pounds of fertilizer that she bought in bulk ($1,000 for 2,000 pounds). It took her employee 1.5 hours to spread the fertilizer (she is paid $15/hour) with the motorized spreader. Toby paid $4,000 for the spreader three years ago and it is estimated to last 10 years or 10,000 pounds. To get to the job site, a company truck and trailer was used (cost: $40,000 expected to last 10 years or 200,000 miles, the site visit was 30 miles round trip). This was the only use of the truck, trailer, and spreader for that day. Additional employee costs include 10% payroll tax and $730 per year in worker’s compensation insurance. You may assume an employee works 2000 hours per year.

Create an Input area in Excel of given information, and do calculations done by formula within Excel (including cell references). Separate and label the parts of the calculation as Direct Material (DM), Direct Labor (DL), or Overhead (OH). Please make two calculations comparing the straight-line depreciation method with the units of production method.
