A spaceship initially at rest is propelled to a Lorentz factor ? = 8 (speed of 0.9922c). The mass of the spaceship is 20,000 kg; neglect the mass of the fuel.

a. How much energy (in J) would be required to do this? [Hint: Use equation (9-5). Your answer will be in joules (J) if you use c =3.0 ?108 m/s, since 1 J = 1 kg m2/s2.] [2 points]

b. How much mass in fuel would be needed to create this much energy at the highest possible efficiency, 100% conversion of rest-mass into energy? [Hint: Use the equation E = mc2 and solve for m.] [1 point]

c. Was our neglect of the mass of the fuel correct in this case, or is much more mass needed in fuel than in the structure of the spaceship? That is, can space travel near the speed of light be fuel-efficient? [1 point]

X and Y want to predict the outcome of the elections in their congressional district. X has been travelling to all neighborhoods of the district to ask people’s opinions about their favorite candidate. X has interview 2000 people and has found that 40% of them support the democrat candidate. Y has created a website where people can express their political opinions and he has advertised his website by putting some posters near his house. Y has found that 4000 people has entered his website and only 30% of them have expressed support for the democrat candidate.

1. Construct two99%confidenceintervalsforthetrueproportionofdemocrats in the district, one for X and one for Y.

2. Which confidence interval has the largest range?

3. Whose poll would you trust the most? Is there any reason why you would trust X’s results more than Y’s results?

Part A: Ranier Ltd. has just completed its first year of operations on December 31, 20X1. Net income for the year was $570.

Near the end of the year, equipment costing $60 with accumulated depreciation of $16 was sold for $54. At the end of the year, accounts receivable was $250, accounts payable was $36 and accumulated depreciation was $144. A bank loan of $140 was received during the year to help finance operations. At the end of the year, the bank had been paid $52 including $14 of interest. Based on the above information, please prepare the statement of cash flows for the year ended December 31, 20X1 using the indirect method.

Part B: How does the information in the statement of cash flows help the user of the financial statement?

Discussion Question, choose one of the following:

Provide an example of a real-world industry or market that has not been described by another student that would be described by economists as a natural monopoly. Why might government want to regulate natural monopolies? Find a recent article on how the government is regulating that natural monopoly and provide a summary of that article along with a link to the article. Make sure you know the definition of a natural monopoly as most monopolies are not natural monopolies.

OR

Provide an example of a real-world industry or market (current or historical) that has not been described by another student or that is in the text that would be described by economists as a monopoly (near-pure or natural) and provide a summary of how that monopoly became a monopoly, how it maintained monopoly power, and if applicable, how it lost its monopoly power. Provide a link to your references (Do not use Wikipedia).

Please make a little adjust for the following script then make it work for

Runge Kutta method

Consider the initial value problem

du/dt=t^5   u(0)=0

0<=t<=1

Q1. how we change the below script to make it to solve the above IVP and the answer should be near 4

here is the script

f =@(t ,y)(t^5); % define f by f(t,y)=y^5
for k =1:10
[ tlist , ylist ]= RKfour174 (f ,0 ,1 ,0, 2^k);
error1 (k)= max ( abs ( ylist - ( tlist )));
hlist (k) =1/2^k;
end
x= log ( hlist );
y= log ( error1 );
polyfit (x ,y ,1)

function [tlist,ylist] =RungMethod(f,t0,tfinal ,y0,N)     what is the input for N, n is a stepsize

Mr. Jackson is a 38-year-old African American that presents with an altered level of consciousness (ALOC). He has been having headaches for the last three months but due to a hectic work schedule he has not been able to go to see his medical practitioner. During his last visit two years ago, his blood pressure was slightly elevated, but he never followed up. Upon arrival to the ED a CT scan is completed and it shows a large bleed near the frontal lobe. What should Mr. Jackson's plan of care include?

Which of the following alterations would likely contribute to the formation of a cancerous somatic cell?
