Calculate the total power, in units of erg s−1
<br/> -Calculate the total power, in units of erg s−1, that the 300
meter diameter Arecibo radio telescope would see from the planet Neptune (radius 25000 km, 30 AU away), assuming Neptune is a blackbody at temperature 30 K and Arecibo is sensitive between 10 and 30 cm wavelength (with zero sensitivity elsewhere)
