Should the speed of two artificial satellites of the earth having different masses but the same orbital radius, be the same?

They will be placed at the same slot as their atomic number is same, valency electron and valency are same and have the same chemical properties.

They should be placed in the same slot. Since they have same numbers of electrons.

We know that distance of geostationary satellite from the surface of earth is 36000 km.  The radius of earth is 6400km.  Therefore, distance of geostationary satellite from the centre of earth =...

(a) the torque is zero. 

(c) of viscous forces causing the speed of satellite and hence height to gradually decrease. 

n + l rule : For 3d = n + l = 5 4s = n + l = 4 So electron will enter in 4s orbital. Ionisation enthalpy is responsible for the...

(a) Yes, because at the bottom depends only on height and not on slope.  (b) Yes, greater the inclination (θ), smaller will be time of decent, as t ∝ 1/sin θ .

Following are the basic conditions:  (i) The rocket must take the satellite to a suitable height above the surface of earth for ease of propulsion.  (ii)From the desired height, the satellite must...

Both the balls will rise to a greater height. 

Isomers. The compounds having the same molecular formula but different structural arrangements of atoms
