According to Stefan’s law of radiation, a black body radiates energy $\sigma=\text{T}^4$ from its unit surface area every second where T is the surface temperature of the black body and $\sigma=5.67\times10^{-8}\text{w}/\text{m}^2\text{K}^4$ is known as Stefan’s constant. A nuclear weapon may be thought of as a ball of radius $0.5m$. When detonated, it reaches temperature of 106K and can be treated as a black body.
  1. Estimate the power it radiates.
  2. If surrounding has water at $30C°$, how much water can $10\%$ of the energy produced evaporate in $1s$?
