Homework Statement
Ive been tasked with working out the Latent heat of steam
the following are all my results and values used.
Mass of the calorimeter and stirrer: 0.068Kg
Thermal Capacity of the Calorimeter and Stirrer : 25.772 JK-1
Mass of water and Calorimeter and stirrer: 0.145Kg...
thanks for the reply, I've tryed checking in the libary, but eather we have nothing on the aurora or its just been miss referanced and placed in some area, so while i am useing google far to much I am sticking to places that are gov or edu, and pref with full referencing.
yes. any comments...
In my physics class we have been set to do a poster presentation on anything to do with the Earth or atmosphere that has a physics basis.
Before on presentations It's been on a subject I've researched myself so was able to do the Introduction, method, results, discussion.
Because its a...
Perhaps there is an issue with my calculator then, because it keeps giving me 2x10^13 every time.
Casio: fx-85ES.
entered in as (3.2x10^-6) Devide (1.6x10^19) = 2x10^13
Edit. Its done this to me once before, not sure why but had to remove batterys and replace them then just did it, and...
not quite, I understand that if its a postive charge on the nail ill need to add a negative charge to counter it.
and that the total charge devided by the charge per electron would show the number of electrons required, all I can't get is why 1.6x10^-19 needs to become 1.6x10^19 in order to...
Thanks that helped some, and I've been trying to backwards work the equation. Based on the test questions the answer is 2.0x10^13
The only way I can obtain that actuall answer is to make the equation.
3.2x10^-6 / 1.6x10^19 = 2.0x10^13
Is this pure chance or is there some step I am not...
Last question out of all the ones I've done has got me 100% stumped, went and asked the tutor and he confessed he has not coverd this at all but desided to leave it into the practice questions, so wondering if anyone here might be able to explain how this works.

An FM radio station generates radio waves that have a frequency of 95.5 MHz. The frequency of the waves from a competing station have a frequency of 102.7 MHz. What is the difference in wavelength between the waves emitted from the two stations?
f1= 95.5
f2=102.7...
