Hi,
We have been supplied an Iodine (I2) solution 0.005M.for an experiment but we are supposed to standardize the iodine solution (which i guess means that to find the exact concentration of the I2 solution)
My idea is that we should do a titaration,but I don't know how to or what to do.
So if...
hi i was doing the speed of sound using resonance tube and we kept n constant and changed length and and found frequency.
Tone gen app for iPhone was used to find frequency.we can change it to find the best resonance and record the frequency that gave the best.
thanks for pointing out the mistake its hear.
but experimentally when I was finding the speed of sound i found 587.2Hz as a result I am looking for the uncertainty i can use to add to the graph.
since we heard the frequency i thought uncertainty should bee the human hearing difference
what can be the uncertainty of the frequency that humans can hear ?
I'm aware that there are many ways,but i tried google-ing to find them but i couldnt.
if you could help me it would be great.
yah makes sense now.
So what do you want me to answer now.
im pretty much stucked in the same place since 12 hours without knowing the answer.
and doing researches
so can you please tell me so that i can take a rest
im thinking how to show that there is a point where the string would break. and show that using there is a mass it can hold.
ive done my practical changing mass and taking the stretched distance
Homework Statement
physics major practical, I was supposed to change the mass and find how it effects the safety of the jumper.But since hooks law doesn't follow bungee cord i really can't find a relationship.Homework EquationsThe Attempt at a Solution
I used a bungee cord and hung different...
