As the foci of an ellipse move closer together, the ellipse becomes more circular in shape. When the foci coincide, the shape is a circle. Note that circles are a subset of ellipses.
The point (x, y) is moved to (x+pi/4, y).
In one hour the snail moved 0.25, therefore the speed was 0.25 per hour

The simple answer is that an ellipse is a squashed circle.A more precise answer is that an ellipse is the locus (a collection) of points such that the sum of their distances from two fixed points (called foci) remains a constant. A circle is the locus of points that are all the same distance from a fixed point. If the two foci are moved closer together, the ellipse becomes more and more like a circle and finally, when they coincide, the ellipse becomes a circle. So, a circle is a special case of an ellipse.
Basically a circle has a constant radius throughout and an ellipse does not.a circle has a constant radiusan ellipse has two foci. they are at either end of the ellipse

When the poles are moved closer together to a distance of one inch apart, the magnetic field between them becomes stronger. The force between the poles also increases, resulting in a higher attractive or repulsive force depending on the orientation of the poles. The magnetic field lines become more concentrated between the poles due to the shorter distance, causing a stronger effect on nearby magnetic materials.
The Kaulitz twins moved to Hamburg, Germany, to be closer to their studio. They live in an apartment together. cute :P
Kepler described the orbits of planets around the Sun as an ellipse with the Sun at one of the two foci.

Well, darling, when you move an object closer to the screen, the shadow it casts will appear larger and more defined. This happens because the object is blocking more light from reaching the screen, creating a more prominent shadow. So, in simple terms, bring that object closer and watch that shadow grow!
If the object is moved closer to a convex lens, the image distance will decrease and the image will move closer to the lens. The image size may increase depending on the object distance and object size relative to the focal length of the lens.
the gravitational force pulling them together is reduced.
When two unlike magnetic poles are moved closer together, they will attract each other and the magnetic field lines between them will become stronger and more concentrated. This attraction will continue to increase as the poles move closer until they eventually come into contact.
