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
Answer:
(E) Second law of thermodynamics
Explanation:
The second law of thermodynamics can be understood according to Clausius' words: In an isolated system, no process can occur if a decrease in the total entropy of the system is associated with it. These processes are associated with energy transformations, in which a variable is introduced, called entropy that indicates the notion of disorder. Therefore, in any isolated process, the disorder can only grow.
The heat Q transferred to cause a temperature change depends on the magnitude of the temperature change, the mass of the system, and the substance and phase involved.
