In an attempt to reduce the extraordinarily long travel times for voyaging to distant stars, some people have suggested traveling at close to the speed of light. Suppose you wish to visit the red giant star Betelgeuse, which is 430 ly l y away, and that you want your 20,000 kg k g rocket to move so fast that you age only 38 years during the round trip.


How fast must the rocket travel relative to earth?


How much energy is needed to accelerate the rocket to this speed?


How many times larger is this energy than the total energy used by the United States in the year 2000, which was roughly 1.0×1020J1.0×1020J?

Define the interface for a queue ADT and implement it in two ways: one with a dummy node (or nodes) and one without.
In addition to the two standard queue functions you’ll need a function to create/initialize an empty queue,
a function to free an existing queue (which may not be empty),
and a function to return the size (number of keys) in the queue.
All functions should be as efficient as possible, e.g., the complexity of enqueue and dequeue must be O(1).
An additional requirement is that the underlying data structure should not be a doubly-linked list.*/

111 m3/min of hydrogen measured at normal conditions and nitrogen at a 300% excess enter an isobaric reactor. The inlet gases at 490°C are reacted in the presence of a catalyst to synthesize ammonia. The process has an efficiency of 33%. The exhaust gases are cooled to -40°C to condense the ammonia. Assume that the Cp of the gas phase species can be used in the temperature range, and that Cp NH3 (l) = 0.071938 kJ/mol K. Calculate the overall heat flow of the system in kW.

Two stationary positive point charges, charge 1 of magnitude 4.00nC and charge 2 of magnitude 1.70nC , are separated by a distance of 39.0cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.

What is the speed vfinal of the electron when it is 10.0cm from charge 1?

At an output level of 18,500 units, you have calculated that the degree of operating leverage is 2.10. The operating cash flow is $44,000 in this case. Ignore the effect of taxes.

a. What are fixed costs? (Do not round intermediate calculations and round your answer to the nearest whole number, e.g., 32.)

b. What will the operating cash flow be if output rises to 19,500 units? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)

c. What will the operating cash flow be if output falls to 17,500 units? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)

Innovation is the driving force in development; without innovative entrepreneurs we would not have most of the tools and services that provide many of us with prosperity today. From birth control to the internet, innovation has fundamentally changed the world. Despite this, most of the work on understanding the process of innovation and its relationship to public policy has been conducted in economies at more advanced stages of development. In fact, the importance of innovation is often downplayed for developing countries.
Discuss the conditions under which entrepreneurs in developing countries innovate.

The better-selling candies are often high in calories. Assume that the following data show the calorie content from samples of M&M's, Kit Kat, and Milky Way candies.

M&M's Kit Kat Milky Way
250 245 200
210 205 208
240 225 202
230 235 190
250 220 180

Test for significant differences among the calorie content of these three candies.

A) State the null and alternative hypotheses.

H0: MedianMM = MedianKK = MedianMW
Ha: MedianMM ≠ MedianKK ≠ MedianMW

H0: All populations of calories are identical.
Ha: Not all populations of calories are identical.    

H0: Not all populations of calories are identical.
Ha: All populations of calories are identical.

H0: MedianMM = MedianKK = MedianMW
Ha: MedianMM > MedianKK > MedianMW

create a Java application program that will add up the cost of three items, then print the final total with sales tax.

You should begin by prompting the user to enter three separate prices for three items that are being purchased. For each item you should ask for (in this order) the quantity of the product and the price of the product.

The program should compute, and be able to print to the screen:

the subtotal (the total amount due before tax)

sales tax (the amount of sales tax that will be added, assume 7% tax rate)

total due (subtotal + sales tax)

The following is an example of what your MIGHT see on the screen when your program runs. The exact output depends on what values that the user types in while the program runs. The user's values are shown below in italics:

Enter the quantity of the first product: 3
Enter the price of the first product: $5.25
Enter the quantity of the second product: 2
Enter the price of the second product: $1.83
Enter the quantity of the third product: 7
Enter the price of the third product: $0.89

Subtotal: $25.64
Sales Tax: $1.79
Total Due: $27.43
