One more thing..just to remind u guys...please dont answer your precaution simply like this:
-To avoid parallax error
It is incomplete, u need to specify how to make those correct reading..refer to the table..u should answer like this:
Avoid parallax error by placing the eye such that the line of view is perpendicular to the scale of the ruler.
I know the list in the table doesn't cover all chapters..
hey i aint the type who like to spoon feed everything ..
If u wanna an A for physics..do some xtra work kay or come to my tuition class ;)
