If a van de Graaff generator had a strong positive charge on its spherical surface and you moved your finger closer and closer to it a sall sark might appear between you finger and the spheres surface?

How matter and energy exchanged between the spheres?
Matter and energy are constantly exchanged between the spheres through different processes. These processes are in the form of chemical reactions, radioactive decay, the radiation of energy, & the growth and decay of organisms.

Examples of charge by induction?
An example of an induction charging of two metal spheres. The metal spheres are supported by insulating stands so that any charge acquired by the spheres cannot travel to the ground. The spheres are placed side by side (see diagram i. below) so as to form a two-sphere system. Being made of metal (a conductor), electrons are free to move between the spheres - from sphere A to sphere B and vice versa.
What is the distance between two spheres each with a charge?
You can place them at any distance you like.
What were JJ Thomson's discovery?
J.J. Thompson worked to develop the atomic theory. He discovered that atoms have separate negative and positive material. Before him, it was widely believed that atoms were just spheres of matter.
How are elliptical galaxies perfect spheres?
They are not perfect spheres. If they were, they would have been called spherical, not elliptical!
Are the moon sun and the earth perfect spheres?
No but they are of a spherical shape
What shape are planet?
The inner planets have a spherical shape. In fact all planets are more or less spherical.
Are the sun and planets round?
Yes!!!! The correct term is "spherical", which means round in all dimensions like a ball. (A hoop is round, but is not spherical) Stars and planets are not perfect spheres, but they are very close to perfect spheres.
What shape is the earth and moon?
Spherical. They are approximately spheres. The earth is more of an oblate sphere, a squashed sphere - this is due to its spin.
Is the planet Venus spherical?
Yes, all planets are spherical. They all have a slight bulge at the equator due to rotation, but are almost perfect spheres.
How do planets develop their spherical shape?
Gravity pulls the asteroids into spheres when they get big enough.
When an aircraft travels quicker than the spherical waves it produces the overlapping spheres form?
A shock wave
What planet has dark spheres that reflect light from the sun?
I might be missing the point of this question, but surely the "dark spheres" are just spherical moons. The obvious answer is Jupiter, because it has several such moons.
Why is Mercury spherical?
The reason Mercury droplets are spherical is because they do easily wet other surfaces. For this reason, mercury forms spheres, which have the smallest possible ration of surface area to volume.
Why do slightly non spherical particles aspect ratio 1.03 pack denser than perfectly spherical particles?
A sphere cannot "tile" with other spheres as well as, for example, a cube can with other cubes. This results in more empty space between the particles, and therefore a lower density. Also, there's no such thing as a "perfect" sphere, or circle.
What is the study of spheres and cylinders in math called?
Spheres and cylinders are studied in geometry. In fact there is a geometry that just deals with spheres called spherical geometry. Imagine living on a sphere ( you almost do) compared to living on a plane. Some geometric postulates must be modified for this.There is a geometry of living on the surface of a cylinder too.
