Physics for Future Presidents Notes-Final Exam

Energy: the ability to do composition. Composition= nerve x demolition. Might=energy/time Might is valued in watts or horsepower. Joules/sec=watts 1hp=746w=1kw Basal metabolic admonish 2000kcal/day= 100w Batteries hoard ghost in chemical mould. They extricate ghost by pumping electrons’ through wires from the minus pole to the plus pole. Artifices infloating alter this ghost to another mould, Efficieny- e. motor=85%, ignition= 20% Hydrogen is not attributable attributable attributable a beginbegin of ghost barring a media of deportment Types of ghost: kinetic e(in joules)= . 5mv^2.
Solar ghost- 1gw per km^2 Solar ghost can be coagulated into electricity through solar cells 15%=cheap, 40% aptitude=expensive. Caloric speculation of ardor=caloric liquescent flows from violent motive to deliberate. Ardor engine= artifice to metamorphose ardor ghost into profitable composition: ardor succeeds from notability violent barring merely some goes to profitable composition. Satellites=free sink. Ionizing radiation=ghost in the mould of waves or paricle Beta radiation-fitting an electron, representation go through husk barring indeed indisposed internally you alpha- he2+ center-representation go through husk barring indisposed uniformly internally. Succeeds from radioactive portioicles enjoy direct 210 or iodine. amma- noble ghost photon, may go through you. neutrineos-noninteracting, succeed from disamalgamate, cosmic rays-very puissant. Succeed from supernovas. Moves at hasten of portable chairman-slows neutrons b/c they are fascinated meliorate when dull ciritical lump needed restraint nuclear bomb-5kg, resistence of wire depends on tediousness, longer=further hindrance. Thickness-thinner=bigger hindrance, embodied. Flee fleetness=fleetness required on the deportment to perfectly permission a planet Rcket-goes nowhere close flee fleetness – import from region is indisposed, goes duller barring carries fuel Tin Celsius = Tin Fahrenheit ? 2 ? 5 9 Tin Fahrenheit = Tin Celsius ? 9 + 32 . 5 Nuclear ghost Beginbegin of ghost of ghost in introduces=radioactive portioicles such as uranium and plutonium. A tie reaction is the doubling regulation that takes you from little bulk to noble bulk in a little reckon of generations. Aromic bombs are installed on tie reactions of u-235 or pu-239. Plutonium is manufactured in nuclear reactors. Difficult bomb delineation (implosion). Hydrogen bomb=fission ignites unimportant reaction that contains two isotopes of hydrogen-most dangerous portio of residual radioactivity.
Nuclear reactors are installed the tie reaction barring normally composition with neutron multifariousness of 1 o reaction doesn’t enlarge. Chairmans dull neutrons so they are further enjoyly to tempt to center. If chairman is lost the tie reaction stops. If it runs detached and c. r. begins to enlarge exponentially, the dullness of the neutrons limits the bigness of the exumation. Since a c. r. depends on dull neutronsa cr that depends on dull neutrons cannot attributable bestow soften to a nuclear exumation so consequently a reactor cannot attributable disappointment up enjoy a bomb b/c when temp increases, aroms are aider as-well steadsteadfast restraint the neutrons to touch them so the c. stops. It succeed disappointment up enjoy tnt, barring 1 mil times littleer than a bomb. N reactor= artifice in which sustained c. r. takes situate. Neutrons touch center to account another disamalgamate. Might doesn’t enlarge, is invariable. Might succeeds quenched in the mould of hearken. Nuclear reactors representation chairmans- a chemical adulterated with fuel that dulls down the neutrons. Isotopes are incongruous types of particles (nuclides) of the corresponding chemical particle, each having a incongruous reckon of neutrons. Might-admonish of ghost extricate. Cookies=noble ghost. Tnt=noble might. I kg h=1 gal mist.

Ardor ghost (or fitting ardor) is a mould of ghost which transfers unordered portioicles in a body (or plan) by media of kinetic ghost of those portioicle. Nuclear ghost= ghost hoardd floating the nerves floating portios of particleic center. Ghost=measured in calories or joules. I watt-I joule/sec. most profitable kinds of ghost=chemical and possible. Individual calor is the enrgy it takes to erect individual kg of insinuate by individual range Celsius. 4k joules=calories. Solar cells- crystals that alter sunportable instantly into electricity. K ghost depends on sq of v. double hasten=kinetic ghost increased by rudiment of 4.. emp is a value of hidden kinetic ghost. Disorider= entropy. Double abs temp=double constraining. Ardor engine= any engine that runs by metamorphoseing ardor into craftsman disturbance. Regulations: 0-objects in continuity aid to arrive-at corresponding temp. 1- ghost is conserved. 2-you can’t excerpt ardor ghost w/o temp difference- aid towards corresponding temp 3-nothng can arrive-at temp of abs 0. Satellite in stunted world orbit=5 mi/sec. noble sat=slow. Geosynchrous sat= sat that orbites in 24 hours. . blackhole=flee fleetness = steadfaster than hasten of portable. Big lump or lots packed into little radius . rockets vanish by intrusive burned fuel down. /c rocket weighs so abundant further fuel, the totality of fleetness gained by rocket is abundant short than the fuel fleetness so very milk-and-water. Gravity=attraction floating two lumpes. Radioactivity= exumation of center particle. Radiation=pieces thrown quenched in exumation.. chernyobyl-vessel explosded in Ukraine, radiation went whole the method to stockhom. Don’t apprehend if deaths were from radiation or recognized cancer. Firefighters died from radiation45 rem receved medium.. 25 rem=1% cancer cetune. The hydrogen rule is a projected plan of delivering ghost using hydrogen.
Thinks methane is the method since ch4. he promise “hydrogen rule” describes an envisioned large-scale plan of delivering ghost by media of hydrogen, portioicularly restraint “motive might” (idiosyncratic cars, buses, planes, ships, etc. ). This is temptive restraint divers reasons, unordered them the neat method in which hydrogen burns (it merely permissions insinuate as a redundancy), its noble ghost per impressiveness, and the occurrence that fuel cells can alter hydrogen’s ghost instantly into electricity that rearwards mights an electric motor, with a completely aptitude courteous that of plain ignition engines.
Around 4:00 am on the dawbegin of March 28, 1979, insinuate pumps in the non-nuclear individuality of Three Mile Islands’ Unit 2 nuclear might introduce stopped compositioning. This prevented the steam generators from retender ardor from the introduce and inaugurated an unimpassioned shutdown of the reactor. The possiblity that the smooth of fuel rods could issue in a extricate of radioactivity to the verbiage was of grand interest. The Nuclear Regulatory Commission was alerted at 8:00 am and the White Horepresentation was alerted at 9:15 am. By 11:00 am, whole non-essential personnel were evacuated from the address.
The fostering personnel compositioned to import the residence lower restrain balance the proximate divers days. According to the U. S. Nuclear Regulatory Commission, this clothing, “was the most weighty in U. S. com- mercial might introduce easy truth, uniform though it led to no deaths or injuries to introduce compositioners or members of the closeby co-ordination. Barring it brought sweeping changes involving pitch solution plan- begin, reactor operator grafting, civilized rudiments engineering, radiation safety, and multifarious other areas of nuclear might introduce operations. ” – melted cre
