Develop an algebraic relationship that describes a satellite moving in a circular orbit around a planet if the speed of the satellite is v, the mass of the planet is m, the mass of the satellite is m, the radius of the planet is r, and the altitude of the orbit is h. (you may include the appropriate constants as needed.) assume that the frictional force is negligible. what will eventually happen to the satellite if the frictional (drag) force is not negligible? what could be done to compensate for a non-negligible drag force that would allow the satellite to maintain its orbit?

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

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
