1. inverse variation means if the first value rises up. the other value falls. therefore, sa number 1, yung thin wire ang may higher resistance. Formula: resistance(R) = k/A(cross sec. area). where k is constant.
for problem (1) a. Thin wire has the higher resistance. b. use this formula to get the value of the second resistance R1(A1)/A2=R2.
for problem (2) VP=KT
Good luck! Mag aral ng mabuti!
