To calculate the energy emitted per unit time by Venus, we can use the Stefan-Boltzmann law, which relates the total energy radiated by a blackbody to its temperature:
Energy emitted per unit area per unit time = σ * T^4
Where:
σ = Stefan-Boltzmann constant (5.67 x 10^-8 W/m^2K^4)
T = temperature in Kelvin
First, we need to convert the mean temperature of Venus from Celsius to Kelvin:
T = 46 + 273 = 319 K
Now, we can plug in the values and calculate the energy emitted per unit area per unit time:
Energy emitted per unit area per unit time = 5.67 x 10^-8 * (319)^4
Energy emitted per unit area per unit time = 39354202.619 W/m^2
Therefore, the energy emitted per unit time by Venus can be considered as around 39.35 MW/m^2.
Venus has the mean temperature of 46 degrees Celsius. Calculate its energy emitted per unit time.
