Surface area of a sphere = 4*pi*radius2

For a spherical shell, surface area = surface area of outer sphere - surface area of inner sphere

= 4*pi*(outer radius)2 - 4*pi*(inner radius)2

= 4*pi*[ (outer radius)2 - (inner radius)2 ]

What kind of structure is a geodesic dome?

A geodesic dome is a spherical or partial - spherical shell structure or lattice shell based on a network of great circles on the surface of a sphere.


How does the shell theorem affect the electric field inside a hollow spherical shell?

The shell theorem states that the electric field inside a hollow spherical shell is zero. This means that there is no electric field present within the shell, regardless of the charge distribution on the shell's surface.


What physical phenomenon cause the spherical shape of raindrops?

The spherical shape of raindrops is due to surface tension, which causes water molecules to be pulled towards each other, minimizing surface area. This results in a spherical shape, as it has the smallest surface area for a given volume.


Why small water drops are spherical in shape?

Small water drops are spherical in shape due to surface tension. Surface tension is a property of liquids that causes them to minimize their surface area, resulting in a spherical shape for small droplets as it is the shape that has the lowest surface area. This is why small water drops tend to form perfect spherical shapes.


What is the electric field outside a charged spherical shell?

Outside a charged spherical shell, the electric field behaves as if all the charge is concentrated at the center of the shell. This is known as Gauss's Law for a spherical surface, which states that the electric field at a distance r from the center of a charged spherical shell is equivalent to that of a point charge with the same total charge as the shell at the center. Therefore, the electric field outside a charged spherical shell decreases with the square of the distance from the center of the shell.

Why is a bubble spherical?

The spherical shape is the smallest surface area for a given volume. This comes about naturally when a surface under pure surface tension contains a fluid volume.


Why does water become spherical when thrown in air?

Water tends to form a spherical shape when thrown in the air due to surface tension. Surface tension causes the water molecules to stick together and minimize the surface area, forming a spherical shape, which has the least surface area for a given volume.


Why the raindrop is spherical?

Raindrops are spherical due to surface tension. Surface tension causes the water molecules on the surface of the drop to attract each other, minimizing the surface area and forming a spherical shape, which is the most efficient way to contain the water molecules.


Which physical phenomenon is attributed to tendency of a liquid drop to assume spherical shape?

Surface tension is the physical phenomenon that causes a liquid drop to assume a spherical shape. This is because a spherical shape minimizes the surface area of the drop, thereby reducing surface tension energy.
