If the resistance of a piece of wire 200m in length and cross-sectional area 1mm^2is 4.88hom what is its resistivity?

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

In this problem it decreased 20%

Ithink the answer is: it is likely.
