Edexcel PHY3 Practical

Okay, so I've been given a set of practical papers by my teacher, to complete as practice, before the real thing next Wednesday/Thursday.

http://files.filefront.com/PHY3+Practicalzip/;10131582;/fileinfo.html

How would I go about discussing 'the extent to which my results confirm the relationship' (May 2002, Group 1, Q1B, part b (i))?

I've found two similar values for k, but I don't really know what/how I'm meant to compare...


Attached is the mark scheme. It contains (I think) more than just the answers to the papers, so be careful. The papers themselves should provide you with sufficient preparation for Wednesday/Thursday's exam...

As you have found two values of K, thats two marks out of four.

Find the percentage difference in your values of K.

= Range/average X 100

If you get less than 10 percent , your results confirm the relationship within uncetainty of meters.

Someone posted these on tsr before, I can't seem to find the thread so I attached them. I think it's a mixture of phy3 and phy5 practicals.
kalashnikov - lifesaver! any chance of the mark schemes for those papers??
Unfortunately no, I don't have the mark schemes for them.
