The true equatorial plane is always perpendicular to the Earth's spin axis; this axis is fairly stable but its position drifts about 15 metres (49 ft) during a year and the Equator shifts likewise.t the equinoxes, the Earth's axis is not tilted toward the sun, instead it is perpendicular to the sun meaning that the day is about 12 hours long, as is the night, across the whole of the Earth. Near the Equator there is little distinction between summer, winter, autumn, or spring.
An inductor, also called a coil or reactor, is a passive two-terminal electrical component which resists changes in electric current passing through it. It consists of a conductor such as a wire, usually wound into a coil. When a current flows thr...
Mutators. A mutator is a method that can modify an object. In the simplest case, a mutator just assigns a new value to one of the fields. In general, a mutator performs some computation and modifies any number of fields.Sometimes, accessors are called 'getter' methods and mutators are called 'setter' methods.n accessor is a method that accesses the contents of an object but does not modify that object. In the simplest case, an accessor just returns the value of one of the fields. In general, an accessor performs some computation using the fields as long as that computation does not modify any of the fields.
