Because it only appears to be rolling uphill--it is actually rolling downhill, as it must. The reason for the illusion is as the V-shaped grove the cone rolls widens the contact point on the cone are further from the center thus allowing the CG of the cone to lower as it rolls. Many so-called "Mystery Spots" (like the one in Santa Cruz, CA) use the technique using a ball rolling down a narrow groove that gets imperceptibly wider thus creating the illusion the ball is rolling uphill when it fact is not.

A plane figure formed by the intersection of a double right cone and a plane?

By "double right cone" do you mean one right cone sitting normal with another right cone upside-down atop the first cone? If so, then we you take that double right cone and intersect it with a plane at different angles, you get the conic sections. (i.e. hyperbola, parabola, elipse, circle)


Is a parabola formed when a plane slices through a double cone perpendicular to the bases of the cone?

No. A hyperbola is formed when a plane slices a cone perpendicular to the bases.

What happens to the volume of a cone if the radius is double and the height is unchanged?

Since the volume of a cone is proportional to the square of the radius (look at the formula), double the radius would mean four times the volume.


How do you find the general equation of cone using C language?

If you mean the "general equation of a cone" to be the elliptical cone equation: z = √( (x/a)2 + (y/b)2 ) ... then the function in C to compute this given the proper variables is: double genEqCone(const double x, const double y, const double a, const double b) { const double X_A = (x/a); const double Y_B = (y/b); return sqrt((X_A * X_A) + (Y_B * Y_B)); }

Are stalagmites cone shaped deposits?

Yes, stalagmites are cone-shaped mineral deposits that form on the floors of caves from dripping mineral-rich water. They grow upwards from the cave floor over time, typically made of minerals such as calcite or aragonite.
