2 objects are a race track and an egg. I know this because it was part of my science homework.

There are an infinite number of possibilities. Let A metres be any positive length and let B be 10/A metres. Then the rectangle of size A*B will have an area = A*B = 10 sq metres. Furthermore, there is no requirement for the shape to be a rectangle. It could be a circle, ellipse, triangle etc or a completely irregular shape whose length and width are difficult to define.
Once again the answer from The WikiAnswers Community is wrong. The triangle is an obtuse angled isosceles triangle. And, as inanimate objects, triangles are not usually prone to become pregnant!

An inscribed polygon
A quadrant.
Newton showed that any two objects in space (eg. two planets) whose movement is controlled by gravity will move in a conic section relative to one another. That is why the Earth moves around the sun in an ellipse.
Objects whose density is lower than the density of the fluid they're in float. Objects whose density is higher than the density of the fluid they're in don't.
No there can never be a single point. But yes there are two such points called foci( each called focus) that helps to define an ellipse. An ellipse can then be defined as a curve which is actually the locus of all points in a plane,the sum of whose distances from two fixed points (the foci) is a given(positive)constant . This is further expressed mathematically to obtain the equation of an ellipse.
the objects whose density is more than that of fluid sink in the liquid
An ellipse whose eccentricity is zero is a circle. As its eccentricity increases, it becomes more and more elliptical, i.e. its foci move farther apart and it appears more "egg-shaped".
Quail, quarter, quill and quilt are objects. They begin with the letter q.
Objects whose aggregate density is less than the density of water float in it. Objects whose aggregate density is greater than the density of water sink in it.
They are the objects whose measured speed as a function of time agrees well with theory.
