Yes, the axis of the Earth passes through its centre.
Yes a diameter will ALWAYS pass through the center
No, not all chords of a circle pass though the center of that circle. Any cord that does pass through the center of the circle is called diameter of that circle.
The diameter.
If a right circular cone intersects a plane that runs parallel to the cone's axis but does not pass through its vertex, the resulting curve is a pair of hyperboles.
No, a secant line does not pass through the center of a circle. A secant line is a line that intersects a circle in two distinct points. Only a line passing through the center of a circle is called a diameter.
the equator
No, because to reach the center of the Earth, they need to pass through the outer core. Secondary waves, or S-waves, can't pass through liquids, such as the liquid outer core, so they can't thus even reach the center of the Earth.
By the way earthquake waves refract as they pass through it.
Yes a diameter will ALWAYS pass through the center
yes, the Earth's core is liquid.Scientists have found this out by seismic waves. They are unable to pass through liquid and whilst tracking them, scientists found that they avoid the center, telling us that the center of the earth is liquid.
No, the earth's axis never passes through the moon. In order for that to happen, the moon's orbit would have to pass directly over the north pole, or over the south pole. The moon's orbit is not precisely over the equator, but it doesn't stray from earth's middle by very much. The angle of inclination of the moon relative to the equator can be as large as about 29 degrees. See the link for more information.
the z axis is at right angles to both the x and the y axis. All 3 axis pass through the origin.
No, not all chords of a circle pass though the center of that circle. Any cord that does pass through the center of the circle is called diameter of that circle.
Seismic waves pass through the earth when part of earth's crust breaks.
one whole earth day will pass
yes a diameter passes through the center of a circle
The rays are diffracted toward the center of the lens. This is the principal used in reading and magnifying glasses.
