A spherical black body of 5 cm radius is maintained at a temperature of 327 K What is the power radiated?
The power radiated by a black body can be calculated using the Stefan-Boltzmann law, given by ( P = \epsilon \sigma A T^4 ), where ( \epsilon ) is the emissivity (1 for a black body), ( \sigma ) is the Stefan-Boltzmann constant (( 5.67 \times 10^{-8} , \text{W/m}^2\text{K}^4 )), ( A ) is the surface area, and ( T ) is the temperature in Kelvin. For a sphere, the surface area ( A ) is ( 4\pi r^2 ). With a radius ( r = 0.05 ) m and temperature ( T = 327 ) K, the power radiated is approximately ( P \approx 4\pi (0.05)^2 (5.67 \times 10^{-8}) (327^4) \approx 42.5 , \text{W} ).

What is the radius of a 32 foot spherical water tank?
volume of spherical = 4/3*Pi*Radius^3 = 4/3*3.14*32^3=137188
What is the spherical radius of 1 foot?
It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.
What is radius of curvature of spherical surface?
The radius of curvature of a spherical surface is the radius of the sphere from which the surface is derived. It is defined as the distance from the center of the sphere to the surface at any point. For a perfect sphere, the radius of curvature is constant and equal to the sphere's radius. This concept is crucial in optics and geometry, as it helps determine how light rays behave when they encounter curved surfaces.
What is the volume of a spherical water tank whose radius is 19?

Why is a ball spherical?
Balls can be spherical or not. The (American) football uses a ball that is far from spherical. However, a sphere is a perfect geometrical solid with a uniform radius, and a ball made in that shape is quite suitable for games. It will, for instance, bounce in a predictable way.
What is the radius of a 32 foot spherical water tank?

What is the radius of England?
Radius is a sensible measure to use with a circular (or spherical) shape. England is neither.
What is the percent uncertainty of a spherical beach ball with radius 0.84 - 0.05m?
The uncertainty in radius is approx 5.95%.
What is the radius at the equator of mercury?
It's about 2440 kilometers. Mercury is almost spherical, so the radius is about the same everywhere.
What is the spherical radius of 1 foot?
It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.
Is plain mirror also an spherical mirror of infinite radius?
Yes
What is used to measure spherical radius?
You can measure the diameter, then divide that by 2.
How many spheres of mercury each with a radius of r should combine to form a single sphere with a radius of 3r?
Volume of the sphere varies as the cube of the radius.Tripling the radius increases the volume by a factor of (3)3 = 27.It takes 27 spherical volumes with radius 'r' to fill one spherical volume with radius '3r'.
What is radius of curvature of spherical surface?
The radius of curvature of a spherical surface is the radius of the sphere from which the surface is derived. It is defined as the distance from the center of the sphere to the surface at any point. For a perfect sphere, the radius of curvature is constant and equal to the sphere's radius. This concept is crucial in optics and geometry, as it helps determine how light rays behave when they encounter curved surfaces.
How can a spherical mirror become a plane mirror?
By increasing its radius of curvature to infinity.
Which doesnot change when spherical mirror is broken?
Its radius of curvature and its reflecting property
Would Mercury be large enough to be spherical if the radius was shrunk by 96 percent?
No, it would not, because the smallest possible radius for a spherical celestial body is 200 km (124 miles) and Mercury would only have a radius of 61 miles (98 km) if it was shrunk 96%.
