Hi tevin dear, let m be the mass of the satellite. Force of attraction between earth and satellite will be got as G M m / x^2 Here x is the distance of the satellite right from centre of the earth As satellite moves with angular speed w = 2pi/T its centrifugal force = m x w^2 For satellite to be stable in that circular orbit both forces have to be equal Equating we have m x 4 pi^2 / T^2 = G M m/x^2 Cancelling m we can get x^3 = G M T^2 / 4 pi^2 Plug M, G, and T = 24 * 3600 s we can have x^3 = 75.53 * 10^21 Taking cube root on both sides x = 4.23 * 10^7 m = 42300 km (nearly) As radius of the earth is found to be 6400 km, the height of the satellite above the earth = 35900 km This is called GEO Stationary Satellite Satellite's speed v = x * 2pi/T Hope you would find by yourself using this expression
Satellite is the only way. I live out in the country in the US and I can only get satellite internet through Exede or Hughesnet. And satellite TV instead of cable. However, I do not use satellite TV, because I have a tall antenna with an amplifier on it and so I can get local broadcast.
Satellite is the most likely. Cables need to be laid under the ocean, so it will probably not be viable for small, remote habitations. A very large satellite dish can pick up signals from any satellite in line of sight. Internet by satellite is also used.
There may be two satellites considered for this distinction: one in use since 1965 but which is simply used for calibrating radar, and another which is the longest with functioning electronics, launched in 1974. The oldest object still in orbit is the Vanguard-1 satellite, launched in 1958 but not functioning since 1964 (apart from its historical significance, it is the oldest space junk). The oldest satellite still in use: Lincoln Calibration Sphere 1 launched in May 1965. It has a projected lifespan of 30,000 years! The oldest functioning satellite still in use: Because the LCS 1 is simply a hollow metal sphere, "operational" may be taken to mean a satellite with functioning electronics and which may still be contacted: This would be the AMSAT-OSCAR 7, or AO-7, an amateur Ham radio satellite launched in 1974: Here is a picture of the "Oscar 7" satellite during a vibration test:
The ocean is one environment that gets polluted or can be polluted, yes. I would not put up a general category as an example of pollution of the environment, though. Water pollution, air pollution, soil pollution (contamination), ocean pollution, land pollution, are all categories of environmental pollution, because each defines an environment and says "pollution". You can even have thermal pollution and noise pollution and all are "environmental pollution" because they involve the introduction of something that does not belong where it is being put, or at least not in the amounts that are being put there. For me, examples of environmental pollution include car exhaust going into the air (air pollution), waste chemicals dumped into a river (water pollution), oil drips from a backhoe doing excavation (soil contamination), leaking oil from an underground storage tank (groundwater and soil pollution), and so on. They are all activities which involve the release of a pollutant (a contaminant) into the environment, and thus are "environmental pollution".
nope . Vanguard 1 is still in Earth orbit, although communcation s with was lost every 50 years ago. "...What is the oldest satellite still operating? Vanguard 1 (ID: 1958-Beta 2) was the fourth artificial Earth orbital satellite launched (after Sputnik 1, Sputnik 2, and Explorer 1). It was the first satellite to be solar powered. Although communication with it was lost in 1964, it remains the oldest manmade satellite still in orbit...." Whther you consider that to be "still operating" or not is problematic. It is still in orbit..

What is the value of a sentinel quarter? I assume you're referring to a 1776-1976 US quarter. The reverse side shows a drummer boy, not a sentinel.
