see the stress = F/a and since A=d^2
so for p (it is f/d^2) and for q(f/4d^2) so rtio is 1:4

strain = stress / young modulus
since it is same material the E is same
so 1/E FOR P
AND 4/E FOR Q
SO IT IS 4:1
Divide that by F/d^2...you end up with 1 and 1/4 and not the other way round

my answers :D
1)Am-1k-1
2)1.25*10^4 uncert 775 (6.2% of 1.25*10^4)
the acceleration was 2.6, 169N, 49N
3) 180, 22.9, 90, 90
4) 1:4 and 4:1
5) 24-(2.4*6) = 9.6 , 4ohms, 68.6 W
6) i dont remeber :D
Why did u get 2 90s for the third question?

:/ I am not getting u can u explain how u did It
cux he is subtracting 90 from 180 :p
Dude 4 is in the denominator and not the numerator...so the simplest ratio will be 1 : 1/4. Whaat? I didn't get two same answers for the energy question! I got around 76 J for change in kinetic energy a d that was my last answer :/

um ur 1st answer is for sure wrong..
Where in the world did amphere come from and ur 5th answer the answer to the resistance question was 12 not 40
