According to the National Funeral Directors Association, the median cost of a traditional funeral is approximately $7045. This includes the cost of embalming and a metal casket. The purchase of the gravesite and a burial vault or liner can add as much as $3000 more to the $7045 cost.
Brightness temperature is the temperature a black body in thermal equilibrium with its surroundings would have to be to duplicate the observed intensity of a grey body object at a frequency.This concept is extensively used in radio astronomy and planetary science.the Intensity or Brightness) is the amount of energy emitted per unit surface area per unit time per unit solid angle and in the frequency range between and; is the temperature of the black body; is Planck's constant; is frequency; is the speed of light; and is Boltzmann's constant.
The Sun has a temperature ranging from 6,000Â° Celsius at its surface which is hot enough to turn gold, tungsten and every metal on Earth into gas. It is around 15,000,000Â° Celsius in its center-far hotter than anything we can generate on Earth.Pressure is also enormously high in its center.he temperature of a star is related to its color. Red stars are the coolest while the bluish-white stars are the hottest. Being a yellow star, the Sun emits extreme temperature but not that high as the white ones. Some stars such Vega and Rigel is much hotter than the Sun.
