What is the ratio of resistance to current?
What is the ratio of resistance to current? The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current which flows through it: If the resistance is constant over a considerable range of voltage, then Ohm’s law, I = V/R, can be used to […]

How high are geosynchronous satellites?
How high are geosynchronous satellites? 35 786 km Do geosynchronous satellites move? A satellite in a circular geosynchronous orbit directly over the equator (eccentricity and inclination at zero) will have a geostationary orbit that does not move at all relative to the ground. Satellites in geostationary orbit rotate with the Earth directly above the equator, […]

What will happen if one of the spheres will collapse?
What will happen if one of the spheres will collapse? When one of the spheres is affected then at least one or more of the others will be affected as well because they all work together. For example, when ground breakage occurs in the lithosphere it creates new lakes in the hydrosphere. Lithosphere: the solid […]
