Stefan’s contain (s) derives from other known con- stant of nature, viz. Boltzmann constant, (k) planck’s con- stant (h) and speed of light in vacuum (c). Value of the constant is
`sigma=5.67xx10^(-8)Js^(-1)m^(-2)K^(-4)`
If speed of light were `2%` more than its present value, how much different (in percentage) the value of `sigma` would have been?
