A 4 dimensional object is called a Tesseract or "hybercube"Although if you want to get into string-theory and related advanced subject matters, the Tesseract is not a 4 dimensional object at all, but simply an advanced 3 dimensional object which only represents the 4th dimension; a visual aide if you will.

In that case, it wouldn't be called a "line".From superscot85: No, all lines are one-dimensional, just as all points are zero-dimensional.

The universe.

All of the polygons because they don't have depth

Volume is a tree dimensional measurement consisting of length, width, and height multiplied together. A circle is a two dimensional figure. As two dimensional figures have a height of zero their volume will also be zero. l x w x 0 = 0 A circle is a flat object existing entirely in one plane. All planar objects, regardless of shape have zero volume. They can have area, just no volume.

1. The sum of all forces on an object must be zero.2. The sum of all torques on the object must also be zero (otherwise it will start rotating, even if the sum of forces are zero).1.

Two conditions must be fulfilled for an object to be in equilibrium. 1) The sum of all forces on the object must be zero. 2) The sum of all torques on the object must be zero. Note that these are vector equations. If you want separate equations for each component, you get 3 equations in a plane, or 6 equations in 3-dimensional space.

A map, painting, or photograph, are all two dimensional representatins of three dimensional objects

When the net force acting on an object is zero, then all the forces on the object are balanced.

A cube is a three dimensional object with all faces squares. A cuboid is a three dimensional object with 4, or all 6, faces rectangles (and not square).

All of the polygons except the triangle

When the sum of the net forces on an object are not zero, it means that the object is being moved/pushed/pulled. It means that the object is not in equilibrium. If the net forces were zero, then the object would be in equilibrium, or, a state of not moving at all.

If the net force on an object is zero, then the object is in equilibrium. This means there are balanced forces acting upon it, or none at all.

When the vector sum of all forces acting on an object is zero, the object cannot be accelerated.

When an object as a net force of zero acting on it, that means all of the forces are balanced.

the sum of all forces acting on an object should be equal to zero the sum of all forces acting on an object should be equal to zero

An object in equilibrium must have the sum of the torques be zero or the object will be rotating and not be in equilibrium.

If the velocity is zero, the object is not moving. So if it moves at all, it is changing direction.

parabola

All 12 sides are straight! This is a 2 dimensional object. * * * * * A dodecahedron is NOT a 2 dimensional object so the above answer is utter nonsense. A dodecahedron has pentagonal faces.

It is a surface with zero curvature. It is 2-dimensional and in those two dimensions it extends infinitely far.It is a surface with zero curvature.

Electrons, like all physical objects in the real world, are 3 dimensional (or 4 dimensional if you include time, as Einstein does). Two dimensional objects with zero thickness exist only as mathematical abstractions.

Yes, the net force would be zero if all the forces acting on the object negated each other.
