Why do buildings on permafrost have potential structural issues?
the formula for converting between temperature scales is often one of the formulas printed on the inside of one of the covers of your physics text book. (why do i get the creepy feeling that i need to explain what a 'book' is now ? )
anyway, be that as it may, and it probably is, the formula to take a fahrenheit temperature and convert it to a celsius one is
°c = (5/9) x (°f - 32°)
°c = (5/9) x (125° - 32°)
°c = (5/9) x (93°)
°c = (51 and 2/3)°
electron cloud and nuclei
nuclear energy is the form of energy which is contained in the nuclei of the atoms.
in the nuclear fusion of the hydrogen, two (or more) hydrogen atoms fuse together into a helium nucleus. the final mass of the helium nucleus is lower than the sum of the masses of the original nuclei of hydrogen: this means that part of the mass has been converted into energy, according to einstein's equation
is the variation of mass between final products and initial nuclei
c is the speed of light
the final energy is in the form of radiation/kinetic energy of the products, while the initial form of energy, which is contained in the nuclei of the atoms, is called nuclear energy.
200 joules of work energy are involved. that's all we need to know to answer the question. once we know that 200 joules of work energy are involved, we don't care what was lifted, or how far, or how long it took, or how many people worked on it, or how much they were paid, or what was the distribution of their gender identities, or the ethnic diversity among the team. or what day each of them celebrates as their sabbath. any other information besides the 200 joules is only there to distract us, and see whether we're paying attention.
power = (work or energy) / (time to do the work or move the energy)
power = (200 joules) / (5 seconds)
power = 40 watts
