Answer 9

check your calculations again

R = ρl/A = (1.78*10^(-8))*1.3/(8.36*10^(-6)) = ?

Answer 10

C

Answer 11

good, C is what i got too

Answer 12

D

Answer 13

close but not quite, permits means allows so that would be a conductor

Answer 14

So C

Answer 15

perfect

Answer 16

and conductor would permit and has a low resistance rigt?

Answer 17

yes

Answer 18

D

Answer 19

Answer 21

well done

Answer 22

A

Answer 23

good

Answer 24

A

Answer 25

I'm thinking D maybe based on some quick research :S

Answer 26

OKay!

Answer 27

D

Answer 28

cross-sectional area is in the denominator so we would want the highest cross sectional area and the lowest length

Answer 29

SO A
