Answer:
hey mate !
the Young's modulus remains same as the material remains same of the wire ..
hope it helps..

Answer: No Young's Modulus wont change if the wire is cut into half or any part.
Explanation: Young's Modulus is a ratio meaning that the change in length wont matter as the formula is,
Y=Stress/Strain.
=> F*l/A*L
Where F is Force, A is Area and l is Length and L is change in length.
However the Young's Modulus subjects to change if the object crosses yield point, as given in the figure.
