Measure the diameter and from that calculate the volume, then determine the mass of the sphere on a weighing device. Then it's just density = mass/volume ========================== It again depends on the sphere whether its hollow or its a solid sphere

A sphere is a three-dimensional shape with one surface. Or: An irregular blob, an ellipsoid, a torus, plus other shapes. The most interesting 3D object with only one side is of course the Moebus strip.
Volvox is a motile colonial green alga. It is a hollow sphere with small vegetative cells arranged on the surface. Each individual cell has two whip-like projections know as flagella.
mars is a sphere and is rough
The gravitational force inside a hollow sphere is zero. In a non-hollow sphere of uniform composition, the gravitational force varies inversely with the distance from the center.
If the sphere is conducting, all the charge is distributed uniformly on the outer surface of the sphere.
This is common interview question. A candidate who is asked this question is expected to come-up with as many alternative solutions as possible, while covering a lot of engineering and scientific fundamentals.Here are some I came up with:Suppose you have a plate, one hollow and one normal, of the same material. If you heat both of them, they would expand at the same rate. The hollow plate expands as if the hollow part had the same material in it. But the same does not apply to spheres, because of the pressure of air inside the sphere. So the hollow sphere would expand more and contract more than the normal sphere. (The difference though negligible, can theoretically work).Now, if the balls/spheres are of different materials, we can use any one of plethora of Non-Destructive Testing methodologies When a sphere is manufactured, it is tested if it has any air-bubbles using such test.Use Eddy-current testing if both are conductors of electricity.Use Ultra-sonic testing. (Works for all)
Yes, it can be (a hollow sphere, a hollow sound). The word hollow can also be a noun, meaning a gap, void, or a small valley.
a 44mm sphere that is hollow
true
*concave . curved like a segment of the interior of a circle or hollow sphere; hollow and curved
A sphere has one side. Not tricky! Unless the sphere is hollow, which would have two sides, inside and outside.
become uniformly distributed on the sphere's outer surface.
One if it is solid, two if it is hollow
A hollow sphere.
touch it with a charged object....
