What is the difference between spherical and round?
round is used to described the shape and or form like of the circle,sphere,cylinder,cone, etc. Spherical is the specific description of a sphere. A sphere is a 3D object having volume. Marble is a sphere Coin is a cylinder marble and coin are circle only if it is already a figure(drawing).
How can Thermal energy can be transferred by conduction from one piece of matter to another only if they are what?
touching
What is electric field inside charged metal sphere?
Zero. By Gauss' or Coulomb's law - eclectic field inside a conductor or a charged empty shell is always zero. If there were a field inside a sphere it would never be able to reach equilibrium with itself.
In conductors charge reside only on surface why?
Assuming a stable, static status, we use Gauss's law: Let's assume we're discussion a sphere, even though it works for every shape, it's just to simplify things. If I wrap the inside of the sphere, I will get 0 electric field flow through my "wrapper", because if I had an electric field, it wouldn't have been a static, stable status. So I keep making bigger and bigger wrappers, almost touching the edges of the sphere, but still no electrical field, which implies no electric charge in the wrapper (aka, inside the conductor). When I place the wrapper outside of the conductor, I find that there is an electrical field. which implies it can only be on the outer surface.
How does a spherical capacitor works?
in spherical capacitor two concentric sphere are taken of different radii. one is charged uniformly and placed inside other of greater radii. due to electric induction negative charge come at inner part of second sphere and positive charge come at outer sphere. to vanish this charge we earthed it. only negative charge remains on inner surface which decrease potential of first charged sphere and increase capacity.
Does the earth have only two hemipheres?
earth is a sphere... hemisphere means half of a sphere...
What is tangent to a circle?
"Tangent" to a circle means touching the circle at one point, and only one point. Think of a skinny bicycle wheel standing on the ground. The ground is 'tangent' to the wheel.
Why is a sphere not called a polyhedron?
Because the literal meaning of polyhedron means 'many faces' A sphere has only one face.
A line touching an arc or circle at only one point perpendicular to the arcs?
tangent
What is the difference between spherical and circle?
A sphere is a three dimentional shape, a circle is a two dimentional shape. You can't pick up a circle, it can only be drawn. In differential geometry, a one dimensional sphere is a point, a two dimensional sphere is a circle and a three dimensional sphere is what we call a "sphere", there is no limit to the number of dimensions a sphere can have.
If the surfaces of two spheres S and T with radii 7 and 12 respectively intersect at one point only then the distance between the center of sphere s and the center of sphere T is what?
The distance between the center of sphere S and the center of sphere T is 19.
A line touching an arc or circle at only one point perpendicular to the arc's radius is said to be?
tangent
Describe all of the point symmetries that a sphere would have?
A sphere has one point of symmetry (at its very center) if one considers rotational symmetry in its three dimensions. If one is only considering reflectional symmetry, it would have an infinite number of lines of symmetry.
What does a sphere with a tangent look like?
If your question is " What is the shape of a sphere's tangent?" , then the answer is : a plane. A plane basically touches the sphere at only one point and hence , it should be a plane. It cannot be a straight line , as a straight line is a tangent for 2D objects,( ie.) a circle.
How many surface does a sphere have?
A sphere has a single curved surface. It is said to have one surface. Further, the sphere has no "flat spots" or "angles" or "discontinuities" of any kind. It is a planar figure that is the set of all points equidistant from a single point, which is its center.A sphere has only one surface.
What points point that the earth is a sphere?
Imagine that you are on a beach and there will be a boat coming, if the Earth is flat, you should see the whole boat, but if it a sphere, you should only see the sail first. If you are unsure, try this idea.
Does a sphere have parallel faces?
Since a "face" is usually defined as a flat area and no area of a sphere is flat, the answer would be NO. It is possible to place two planes tangent to the surface of the sphere and parallel to each other, but each plane will only touch the surface of the sphere at a single point rather than coinciding with a "face".
