Welcome to PHY 121 Blog Help. Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

g*sqrt((2*deltak/k)^2+(deltah/h)^2) this is what I am putting as the answer and I don't know why it is wrong. Are they asking us to calculate something? It seems like they want the formula for the error of g (deltag)
I am having the same problem.
I am submitting g*sqrt(((2*deltak)/k)^2+((deltah)/h)^2)
and i don't at all understand why it is incorrect
SAME PROBLEM!!
when you type in deltak or deltah, you gotta do Deltak or Deltah. It has to be exactly how they typed it in the question.
Re all:
g has to be replaced by.... ?
(it says in therms of who ?)
ok. so I've replaced g with (2h/k^2)... now, the full equation I got is: (2h/k^2)sqrt[(2*((Deltak)/k))^2+((Deltah)/h)^2]. Yet, it still says its wrong and I can't figure out why.
i dont get it
I had the same equation as everyone else, and I also implemented the (2h/k)^2 for g, but I kept getting it wrong.
(2h/k^2), I mean! I sent it in anyway but I really would like to know what the real answer was after all labs are over!
I replaced g with (2h/k^2) in equation 3.3, but it is marked as incorrect.
I have noticed that no matter how I close the brackets, it always previews as squaring Deltah exclusively, instead of squaring (Deltah/h)
I have also tried using the symbol entry mode, but it is still marked as incorrect.
Here is a link to my equation.

Re all:
I followed the problem text literally in my comment below.
Code requires actually at the end ...*g.
