Because it basically has to do with three variables. The star's SIZE, its MASS and TEMPETURE.
iron core elements
Nickel and iron or iron and nickel (is the same)
Outer and inner core are made of the same thing: iron and nickel
it has the same core as earth, just on another planet
They both have an iron core, and they have the same density.
the core of venus is very similar to the core of earth, as it is earths twin planet. therefore the the core of venus is made of the same elements as earths core, iron and nickel, both magnetic and it is these elements that create our magnetic field.
No, the moon does not have a liquid core. It is composed of a solid iron-rich inner core surrounded by a partially molten outer core, but this is not considered liquid in the same way as Earth's outer core.
Because, until forging of iron was discovered, the only iron was what came from meteorite or "falling stars."
Iron losses (Pi) are independent of of load which occur due to pulsation of flux in the core. Iron losses include both Hysteresis loss and eddy current loss and is same at all the loads.
No, the earth's core is not gaseous. The core of the earth is under tremendous pressure and is very hot. The inner core is thought to be solid iron and nickel, with liquid iron and nickel comprising the outer core, which surrounds the solid center. A link can be found below to check facts and provide more information.
Both the outer and inner core are layers of Earth's core made primarily of iron and nickel. They are both extremely hot, with the outer core being in a liquid state and the inner core being solid due to higher pressures.
No, the asthenosphere and the core do not have the same density. The core is denser than the asthenosphere due to its composition of mostly iron and nickel. The asthenosphere is less dense because it is made up of partially molten rock.
