The most massive stars in the Universe have a surface temperature that can reach over 50 000 K. Life on planets like Earth cannot exist at 1AU from such stars, it's too hot. Find the emitted power per square meter of peak intensity for a similar star with 43000 K that emits thermal radiation. Express your answer to two significant figures.
A photon has an energy of 1.9 meV (milli electron Volt). What is the wavelength of this photon, expressed in micrometers? Keep four significant digits. And the answer is NOT 6.543
Assume solar flux falling on a typical panel on planet earth to be 1370 Watts per square meter with sunshine at least half of the year and roughly one quarter of the earth surface bathed in sunlight daily as the planet rotates. The best panels convert photonic energy to electrical energy at about 25 % (efficiency). Given that the world consumes around 600 exaJoules (one exaJ = 1028 J) how much area would be required to power up the world with solar arrays. (Give your answer in square kilometers please!)
