1. If `|z-2+il =<`2 then find the greatest and least value of` | z| `

If vecV=x(vecaxxvecb)+y(vecbxxvecc)+z(veccxxveca) and vecV.(veca+vecb+vecc)=x+y+z. The valueof [veca,vecb, vecc] if x+y+z!=0 ils (A) 0 (B) 1 (C) -1 (D) 2

If vecV=x(vecaxxvecb)+y(vecbxxvecc)+z(veccxxveca) and vecV.(veca+vecb+vecc)=x+y+z. The valueof [veca vecb vecc] if x+y+z!=0 ils (A) 0 (B) 1 (C) -1 (D) 2

If z_1 , z_2 are nonreal complex and |(z_1+z_2)/(z_1-z_2)| =1 then (z_1)/(z_2) is

If z_1, z_2 in C , z_1^2 in R , z_1(z_1^2-3z_2^2)=2 and z_2(3z_1^2-z_2^2)=11 , then the value of z_1^2+z_2^2 is

X overset("Setp - I") to Y underset(" 2")overset("Step-II")toZ is a complex reaction. Total order of reaction is 2 and Step - Il is slow step. What is molecularity of Step-Il ?
