For the midterm, I remember Dr.Lavelle said something on Friday about using all the numbers for Plank's constant (or any constant)... for example, instead of using 6.626, we would use all the numbers, which are 6.62607004... would we have to use all the numbers instead of just the first three.. because i remember in class Dr.Lavelle used all of them?
"Known" values don't have sig figs (or so I was taught), so any constant given to you isn't going to determine the sig figs in your work. The point of using the long version of the constant is to ensure accurate calculations.
