What are hysteresis curves?
When a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed. It must be driven back to zero by a field in the opposite direction. If an alternating magnetic field is applied to the material, its magnetization will trace out a loop called a hysteresis loop. The lack of retraceability of the magnetization curve is the property called hysteresis and it is related to the existence of magnetic domains in the material.
Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in

The specific shape of the geotherm beneath any location on Earth is a function of its corresponding local tectonic regime. Metamorphism can occur eitherwith the movement of the rock from one place to another through a single geotherm or when the geotherm itself changes form. The former can take place when a rock is buried or uplifted at a rate that permits it to maintain thermal equilibrium with its surroundings; this type of metamorphism occurs beneath slowly subsiding sedimentary basins and also in the descending oceanic plate in some subduction …show more content…
What is oblate spheroids?
Before we explain an oblate spheroids we have to understand a spheroids;
According to google dictionary a spheroids can be described as;
• A sphere-like but not perfectly spherical body.
• A spheroid is an ellipsoid having two axes of equal length, making it a surface of revolution.
• A spheroid is a three-dimensional shape that can look like either a stretched or a flattened sphere
Now that we understand the fundamental of a spheroids we go into oblate spheroids;
Oblate spheroids can also be described as;
• a solid that can be generated by a half-revolution of an ellipse about its minor axis ( oblate spheroid ).
• An oblate spheroid is a surface of revolution Gotten by rotating an ellipse about its minor axis around a planet or a satellite.
• An oblate spheroid is an ellipsoid generated by rotating an ellipse through 360 degrees about its minor axis around a planet or satellite. Therefore earth is not a perfect sphere neither is it a perfect ellipsoid but it is an Oblate spheroids .
The formula of the ellipsoid is denoted

Simple epithelia: Epithelia tissue can have cell shapes these are the Columnar, Cuboidal, and Squamous Cell Shapes. All this cells shapes are part of a type of an epithelia tissue which is the simple Epithelia. There are columnar cells, which means column-like cells and squamous cells, which are flattened and scale-like cells, simple squamous epithelia is found in walls of lung alveoli, blood capillaries and bowman’s
Uranus is about 4 times the diameter of earth at 46,700km. Its mass is 15 times that of earth at 8.68*10 kg. The axial tilt of this planet is one of the most unusual things about it. It is tilted 98 degrees which classifies it as being in retrograde rotation. Uranus is also unique because it has the most inclined magnetic field. The surface magnetic field is 74 percent that of the earth. The surface gravity on Uranus is 8.87 m/s².
Cells are grouped into three categories namely plant, animal, and prokaryotic cells. In addition, the shape and size of cells range from a few millimeter to microns. The size of a cell is indicative of its function(s). The shape of cells in living organisms may range from concave, to spherical, oval, rectangular, flat, oval, or rod-shaped. The cells can be viewed with the aid of a microscope. Every living organism possesses multicellular and unicellular cells. At the same time, the different types of cells display common structural properties. Examples include the plasma membrane and genetic composition (Jan,
Unlike most planets, but similar to Uranus, Pluto rotates with its poles almost in its orbital plane. Pluto's rotational axis is tipped 122 degrees. When Pluto was first discovered, its relatively bright south polar region was the view seen from the Earth. Pluto appeared to grow dim as our viewpoint gradually shifted from nearly pole-on in 1954 to nearly equator-on in 1973. Pluto's equator is now the view seen from Earth
"A shape is that which limits a solid; in a word, a shape is the limit of a solid."
...ossessed with three dimensional attributes. The optical effect may be explained by the fact that the human eyes see an object from two viewpoints separated laterally by about six centimeters. The two views show slightly different spatial relationships between near and near distant objects and the visual process fuses these stereoscopic views to a single three dimensional impression. The same parallax view of an object may be experienced upon reflection of an object seen from a concave mirror." (http://www.freepatentsonline.com/4229761.html).

...planetesimals that once orbited the sun but were, at one point, captured into a planetary orbit by the planet's gravity. Cratering is also a sign of these period, with the collision of planetesimals into larger ones being the explanation.
The plural of focus is foci. The midpoint of the segment joining the foci is called the center of the ellipse. An ellipse has two axes of symmetry. The longer one is called the major axis, and the shorter one is called the minor axis. The two axes intersect at the center of the ellipseThe center of the ellipse is at (h, k). The radius of ellipses are not a constant distance from the center. To find the distance to the curve from the center you have to find the distance from the center to the curve for the x and y separately, these points are called vertices. The vertices are on the major axis and minor axis. The major axis is the longer axis and the minor axis is the shorter axis through the center of the ellipse. To find the distance from the center in the x direction you take the square root of a2. To find the distance from the center in the y direction you take the square root of b2. You then will have two points on the x direction and two points in the y direction and you use these four points to draw your ellipse. Ellipses are symmetrical across both of there
Since the days of Aristotle, all substances have been classified into one of three physical states. A substance having a fixed volume and shape is a solid. A substance, which has a fixed volume but not a fixed shape, is a liquid; liquids assume the shape of their container but do not necessarily fill it. A substance having neither a fixed shape nor a fixed volume is a gas; gases assume both the shape and the volume of their container. The structures of gases, and their behavior, are simpler than the structures and behavior of the two condensed phases, the solids and the liquids
Diastrophism is deformation of earth’s crust, caused by folding and faulting. Convergent plate boundaries are formed through diastrophism. A convergent boundary (or a destructive plate boundary) is formed when two or more tectonic, lithospheric plates collide. There are two types of plates: oceanic (more dense) and continental (less dense). If two oceanic plates collide, subduction will occur. Subduction refers to the movement of one plate, sliding underneath another plate. The plate that is pushed down is consumed by the magma in the internal structure of the earth. When this happens, there will be a large, deep underwater trench where the subduction occurred (Mariana’s trench is an example of this). The plate that is consumed by magma causes
