M&G question..
this is a really simple question and i want to know if i got the right answer cuase the one in the book is different to what i got :chainsaw: :chainsaw: :chainsaw:
the book has 12.5N and i got 62.5N :confused:
We are in class right now and we are stuck in what are rayls (referring to acoustic impedance)
What are the units for Rayls?
there are several answers from different text books such as kgm^-2s^-1 or kgm^-2
thanks :)
can we have a photography forum also as part of the General list?
im sure theres a lot of budding photographers (like me :D ) who would want to ask other ppls for tips etc :)
