K, so we are doing this lab in physics where a ball on a string is put through a glass tube and then different washers (masses) are added to the string. A radius is measured out, and then the string is spun in a horizontal direction...so with different ra...

I have 2 questions...one can someone please read my question posted around noon today called Lab for physics? Thanks..and secondly, I have to derive some equation. I am supposed to show a=gtantheta and find this from m (mass) L (length). The question also...

bobpursely, I posted at 709 from our previous dialogue, can you please help me again? Much appreciated!

I completely faill to understand where you are getting these equations from, and how & why you are using them. Firstly, the mass at the end of the string that hold the washers on it, it was never measured, none of the groups measured it, I didn't even thi...

So I understand the lab thing now completely! Thanks so much..and I sort of understand what you are doing for this derivation, but can you give some more of an explanation for where you are getting the equations from? Thanks a million!
