How did Bohr's model differ from Rutherfords?
In Bohr's model there are stationary orbits in which though the electrons are subjected to centrifugal acceleration, they will not give out any kind radiation. But in Rutherford's model no such stationary orbits. In case Bohr's model, line spectrum is possible. But in Rutherford's model, continuous spectrum is expected. But no such spectrum emitted by atoms especially hydrogen atom

Does the sun stay in place by gravity?
Asked in Artificial Satellites, Astronomy
Are man made satellites stationary?
No satellite is stationary. However, a few satellites travel in orbits that appear relatively motionless compared to other things. IF a satellite is placed in an orbit with the proper major-axis, and IF the orbit is perfectly circular, and IF the orbit is in the plane of the equator, then the satellite APPEARS stationary over a point on the equator. Such a satellite is in a geostationary orbit (a kind of geosynchronous orbit), also called Clarke Orbit. You can point a satellite dish at such a satellite and it will stay pointing at it, no motors needed. A few observatory satellites are in orbits near the L1 Lagrange point. From Earth, such satellites appear to stay nearly stationary relative to the sun.
Is Polar Orbit a type of Geosynchronous orbit?
No. A geosynchronous orbit is one in which the satellite stays approximately stationary with respect to a point on the earth's surface. This is not possible in any orbits which are not in the equatorial plane of the earth. For example, in polar orbits the satellites will move around the earth from above the north pole to above the south pole and then back to above the north pole. Clearly, this isn't stationary relative to the earth's surface.
