Two artificial satellites (A and B) of earth are orbiting in equatorial plane at such altitudes that their periods of revolution are 4 hours and 16 hours respectively. Sense of rotation of satellite A is west to east while that of B is opposite. After being nearest to each other and lying in a given longitude of earth at a given point of time, the minimum time interval after which both are again nearest to each other and lying in the same longitude is x hours. Find 10x.

A particular satellite was placed in a circular orbit about 328 mi above Earth.(a) Determine the orbital speed of the satellite. m/s(b) Determine the time required for one complete revolution.

Two satellites are monitored as they orbit the Earth; satellite X is four times as far from the Earth's center as is satellite Y. From Kepler's third law one may conclude that the period of revolution of X is what factor times that of Y?Select one:a.2.0b.8.0c.22.6d.1/2

For a satellite to be in a circular orbit 780 km above the surface of the earth, what is the period of the orbit (in hours)?A 1.98 hr B 1.65 hr C 1.78 hr D 1.88 hr

Two satellitesP andQ go around the earth in circular orbits at heights ofh1 andh2 respectively from surface ofearth. Assuming the earth to be a uniform sphere of radiusre, the ratio of magnitudes of their orbital velocities will be(a)(b)(c)(d)6. A planet revolves in elliptical orbit around the sun. The linear speed of planet will be minimum at(a)A(b)D(c)C(d)B7. Wheel of an engine rotates with an angular speed of 120 rev/min. If radius of the wheel is 2 m, then linear speed ofany point on its rim is

A satellite follows a circular geostationary orbit, where its position can be described as x(t)=(Rsin(kt))i+(Rcos(kt))j𝑥(𝑡)=(𝑅𝑠𝑖𝑛(𝑘𝑡))i+(𝑅𝑐𝑜𝑠(𝑘𝑡))j, where R=40,000𝑅=40,000 is the radius of the orbital path in kilometres, t𝑡 is measured in hours, and k=π/12𝑘=𝜋/12.
