Two Artificial Satellites A And B Are At A Distance

Two artificial satellites are in circular orbits about the earth.

Two artificial satellites a and b are at a distance.

Artificial satellites come in several forms including telescopes and probes. Following that feat on nov. It orbited for three weeks before its batteries died and then orbited silently for two months before. A brief history of artificial satellites.

If r 2 2 r 1. The soviet union launched it into an elliptical low earth orbit on 4 october 1957. Two artificial satellites a and b are at a distance r a and r b above the earth s surface. Sputnik 1 ˈ s p ʊ t n ɪ k ˈ s p ʌ t n ɪ k.

Apart from indian rockets these satellites have been launched from various vehicles including american russian and european rockets sometimes as well. 3 1957 the soviets launched an even more massive satellite sputnik 2 which carried a dog laika the united states.

Artificial satellites are used for many purposes including communications navigation gathering weather information creating maps and even spying. India has been successfully launching satellites of various types from 1975. Two satellites a and b go around the earth in circular orbits at a height of r a and r b respectively from the surface of the earth. Two artificial satellites 1 and 2 orbit the earth in circular orbits having radii r 1 and r 2.

The ratio of the magnitudes of the velocities of the satellites v b v a is. C the one with smaller mass. Assume the earth to be a uniform sphere of radius r e. They enter orbit around the earth s atmosphere or travel to other planets after launching through rockets and remain.

If the radius of earth is r then the ratio of their speed will be.
