Answer:
= 2/3
Explanation:
The yuong modulus of a rod is defined as the relationship between the tensile strength and the strain
Y = 
let's use the subscript "o" for rod A
I = 
tells us that rod B has
A = 3 A₀
L = 2 L₀
we substitute
Y = 
Y = 
y = ⅔ 
substituting the value of Y₀
Y = ⅔ Y₀
= 2/3

I hope I helped you^_^
I believe you forgot to add the choices. I will tell you some of the characteristics of mixtures and I hope you find one of them in the choices you have.
A mixture is a physical combination between two or more elements. No chemical reaction is involved in the formation of mixtures.
The components of the mixture can be separated using physical methods such as filtration, boiling and condensation.
Examples of mixtures include mixture of sugar and water or mixture of salt and sugar.
