measure the radius of the sphere and apply the appropriate volume equation: V= (4/3) x (pi) x r3
NONE!!! However, there are two sides to a sphere ; viz. INside and OUTside. Ha!!!Ha!!! Ha!!! My silly joke!!!!!
Find the surface area of the full sphere [ A = 4 pi R2 ] and then take half of it. You wind up with [ 2 pi R2 ] for the outside surface area of a half sphere, or [ 4 pi R2 ] for the (inside + outside) surface area of the half sphere. (Since the inside and outside are now both exposed to the weather, you probably want to paint both surfaces.)
the radius would have to be around 2.45cm.
A triangle (or other polygon) on a concave surface (such as the inside of a sphere), possibly.
The distribution of the electric field inside a sphere is uniform, meaning it is the same at all points inside the sphere.
The electric potential inside a nonconducting sphere is constant and the same at all points within the sphere.
The electric field inside a charged sphere is uniform and directed radially towards the center of the sphere.
The electric potential inside a uniformly charged sphere is constant and the same at all points within the sphere.
The electric field inside a uniformly charged sphere is zero.
Zero, because the electric field inside a charged hollow sphere is zero. This is due to the Gauss's law and symmetry of the charged hollow sphere, which results in no net electric field inside the sphere.
The gravitational force inside a solid sphere is zero because the gravitational forces from the parts of the sphere above cancel out the forces from the parts below, resulting in a net force of zero at any point inside the sphere. This is known as the shell theorem.
The electric field inside a sphere of uniform charge density is zero.
A sphere has one side. Not tricky! Unless the sphere is hollow, which would have two sides, inside and outside.
It's the length of any straight line that's completely inside the sphere and passes through its center. It's the longest possible straight line that can be completely enclosed inside the sphere.
Inside a conducting sphere, the electric field is zero due to the symmetry of the charge distribution. Any excess charge placed inside would cause the charges to rearrange themselves in such a way that cancels out the internal field, resulting in a net charge of zero inside the sphere. This is known as the principle of electrostatic shielding.
The voltage inside a uniformly charged sphere is directly related to the distribution of charge within the sphere. As the charge distribution becomes more uniform, the voltage inside the sphere becomes more evenly distributed. This means that the voltage is higher towards the center of the sphere where the charge is concentrated, and decreases towards the surface where the charge is spread out.
