strain:extension/original length.so i think if u think about it logically,the strain in P must be greater than in Q since P will surely have more extension,thus the ratio must be "something more than 1:1".because more extension means more strain.
im sorry this reply was intended at your other comment about the second ratio.
If it makes u feel better I actually wrote 1:1 for strain even tho I knew it was the wrong answer. I didn't have time to think about it and I thought I could sacrifice 2 marks for 58. It was only after giving it that I thought about that question and realized that the you g modulus is a material property and that it had to renain the same and now I'm realizing that I've list more than 10 marks
I know! So finally my answer will be less by a factor of 9! Damn! Arrgghh...CIE!!
I got that as 827! Quite close!
What? Their spring constant wasn't the same?
Me 2. And it is correct I suppose.
Umm I don't know I don't think so since k depends on area of cross section and material the material is the same but diameters were not so I don't think k is the same.. I really don't know I got that whole question wrong
Oh! I thought they had mentioned something about it...Umm I don't know I don't think so since k depends on area of cross section and material the material is the same but diameters were not so I don't think k is the same.. I really don't know I got that whole question wrong
12 ohmswere you all able to find out X? The resistance question? I had just 5 mins left each for the last two ques so I think I messed up both in hurry.
Oh yes, it was the correct one. I totes messed up mine.
