One of Earth’s deep-space observatories has picked up a precise electromagnetic pulse from a planet designated Xeros-9.  As you look around trying to determine where to help with the analysis, the head of your team hands you a paper with the number [E] pJ on it and yells at you to calculate the amount of photons in this most recent electromagnetic pulse from Xeros-9. please keep in mind there are 1 x 1012 pJ in a J. (Enter your answer as a complete standard whole number (yes, it is a little large) with no units the understood unit is photons.

Use Hess’s Law to determine the energy (

In your communication you have found out many cool and interesting things about planet one is there a flying creatures.  You wonder what the speed of these Virellans are?   You send a message asking for the mass of the Virellans and are surprised to learn that a mole of Virellans has a mass of [m] kg.  As you set of to calculate the root mean speed of these flying creatures, you wonder just how differ this planet is from Earth. (enter the speed you calculated as a 2 decimal place number with no units, the understood unit is m/s).
