Idon't understand any of this, can someone me go through 1) the average chemical bond in your body requires about 5.8x10⁻¹⁹ joules of energy to break it. a) what is the frequency of a photon carrying this amount of energy? b) what is the wavelength of photon carrying this amount of energy? c) what category of electromagnetic radiation does this fall? use the table below as a guide. (table) gamma ! x-ray ! ultraviolet ! visible ! infrared ! < 1x10⁻¹¹ m ! 1x10⁻¹¹-1x10⁻⁸ m ! 1x10⁻⁸-3.8x10⁻⁷ m ! 3.8x10⁻⁷-7x10⁻⁷ m ! 7x10⁻⁷-1x10⁻³ m! radio > 1x10⁻³ m

State the right hand rule of the direction of magnetic field in a conductor carrying current

What is the length x of the side of the triangle below? (hint: use the cosine function)

Comedians like to joke that the reason we haven’t been visited by intelligent life from elsewhere in the universe is that aliens have been monitoring earth’s broadcasts of intellectually embarrassing tv programs, like gilligan’s island, fear factor, the jersey shore, and the jerry springer showand so consider us far too primitive to merit a visit. let’s check the assertion that aliens could have been receiving them. tv programs are broadcast at a frequency of about 100mhz with about 100kw of total power in 30frames per second, which emanatesroughly uniformly in all directions. assume that interstellar space transmits these broadcasts without attenuation. no matter how smart they are, aliens would require at least one photon per frame to interpret our signals. findthe number of photons per unit time per unit area reaching a receiver on a possible planet in the nearest star system, which is about 4 light-years away (a light-year is the distance light travels in a year). if aliens aimed a receiver or detector directly at earth, how big (in diameter) would it have to be to receive a photon per frame
