Question 1143798
.


In this post,  the data is defined/given  INCORRECTLY.


To be correct, &nbsp;the <U>DENSITY &nbsp;of &nbsp;ENERGY</U>, &nbsp;in joules per unit area, &nbsp;should be given, &nbsp;instead of total energy;


or, &nbsp;if the total energy is given, &nbsp;then &nbsp;<U>the area</U> &nbsp;of the sample must be given, &nbsp;too, &nbsp;as a necessary addition.

Hey, &nbsp;if you don't know basics, &nbsp;for &nbsp;WHAT &nbsp;REASON&nbsp; do you post or try to create a problem to post to the forum ?


You &nbsp;CLEARLY &nbsp;don't know the basics -- take a &nbsp;Physics textbook and learn from there, &nbsp;before to become a problems creator . . .
