Determine which materials are used for nuclear bombs. (Remember, a bomb must be transportable - what do you need to do so that it is transportable?) What can you do to make the bomb explode?
The material used for a nuclear bomb:: Uranium enriched with U235 and a container to transport the bomb.
The natural occuring uranium is mostly U238 and it is not fissile to sustain a chain reaction. So, you also need U235 for continuous fission.

do you need any extra information? a component of nuclear fallout from atmospheric tests of nuclear bombs, falls to the ground 90, and crops. When ingested, it can replace calcium in cow's and mother's milk and can be into the bones of developing young animals and children. Strontium-90 decays by beta to yttrium-90 with a half-life of 29 years. (The energy release accompanying this beta decay can s a dust on grass gger leukemia in the bone marrow and other...
Bomb calorimetry is a technique used to determine the enthalpy of combustion, usually in O2, of a chemical species. A known amount of compound is placed inside a fixed volume container that is, in turn, filled with oxygen at a high enough pressure to ensure complete combustion. The fixed-volume container (the 'bomb') is then inserted into a bucket containing a precisely known volume of water. The oxygen and compound are ignited, and the temperature change in the water is recorded....
Reasearch: Determine how long medical records must be kept in Connecticut. Remember to include special circumstances such as minors. Research medical record storage options in your state as well. How can someone properly permanently dispose of a medical record? Complete your research and write your findings in a 1-page paper. Make sure to site your sources.
Ritz Products's materials manager, Tej Dhakar, must determine whether to make or buy a new semiconductor for the wrist TV that the firm is about to produce.One million units are expected to be produced over the life cycle. If the product is made, start-up and production costs of the make decision total $11 million, with a probability of 0.40 that the product will be satisfactory and a 0.60 probability that it will not. If the product is not satisfactory, the...
Create a shell program called "myprog" that prints "Hello" (use echo). Remember it must start with "Shebang" and the entire path to a bash shell. So you need at least 2 lines of codes, though use a blank line between the two. Give the program rights so you have all the rights, your group reading and driving rights, and everyone else just driving rights. Now run your shell program. How can you run the program? Why is just the name...
Material enginering You required to select suitable alternative materials used to produce present day cars. You must do this realising that energy is used to build cars and run them. Consumers and legislation want more fuel-efficient cars. You should suggest materials for the car based on its ability to have the necessary stiffness, strength, formability, and weldability. In addition you must also consider manufacturability, maintainability and disposability at the end of life; i.e., to be disposed of, or recycled, in...
Nuclear reactions can be used to produced short lived isotopes that are of interest to study nuclear properties. For example, the nuclear physics group at UT will measure the decay of 29F (Z=9) in MSU next year. Fluorine-29 will be produced in the fragmentation of a 48Ca beam, resulting in 29F, 2 neutrons and a fragmentation partner. (a) What is the fragmentation partner of 29F? (b) What is the Q value of the fragmentation reaction? Do we have to provide...
Remember all variances must be designated as "Favorable" or "Unfavorable" The Cat's Meow manufactures gourmet cat food. During the month, it manufactured 5,000 cans of tuna, using 0.10 hour of direct labor per can at a rate of $8.00 per hour. The materials and labor standards for manufacturing the cans of tuna are as follows: UNIT SQ Direct Materials (1 pound of tuna @ $0.50 per pound) Direct Materials (1 can @ $0.35) Direct Labor (0.20 hour@ $7.00) $0.50 $0.35...
Given the new found interest in nuclear power plants due to potential carbon taxes, you consider starting a company to build a nuclear power plant. Before you can build the plant, you need to gather permits, fight lawsuits and so forth. That will cost $800 million today and take 5 years to resolve with a 35% probability of success. If you build the plant, you must pay $9 billion the day you start building the plant, which is immediately after...
0.500 g of graphite (elemental carbon) is reacted with oxygen in a bomb calorimeter filled with water, which has a total heat capacity of 2820 J/oC. If the reaction gave off 16.4 kJ and the initial temperature of the water and calorimeter was 22.40 oC, what should the final temperature be? I got 34.031 when i tried it using q=mc(tf-ti) and it was wrong. I really need to learn this so as much work as you can help me with,...
