Question

Which intersection forms a parabola?

A) A plane intersects only one nappe of a double-napped cone, and the plane is parallel to the generating line of the cone.

B) A plane intersects only one nappe of a double-napped cone, and the plane is not parallel to the generating line of the cone.

C) A plane intersects both nappes of a double-napped cone, and the plane does not intersect the vertex.

D) A plane intersects only one nappe of a double-napped cone, and the plane is perpendicular to the axis of the cone.

Answer 1

The answer is B. Parabola is a symmetrical open plane bend framed by the crossing point of a cone with a plane parallel to its side. The way of a shot affected by gravity in a perfect world takes after a bend of this shape.

Answer 2

A) A plane intersects only one nappe of a double-napped cone, and the plane is parallel to the generating line of the cone.

Explanation:

A) Parabola

A plane intersects only one nappe of a double-napped cone, and the plane is parallel to the generating line of the cone.

The plane has to intersect with the base of the cone and forms a parabola.

B) Form Circle and hyperbola

C) Forms hyperbola

D) Forms circle
