Explanation:
It is given that,
Mass of concrete pilling, m = 50 kg
Diameter of wire, d = 1 mm
Radius of wire, r = 0.0005 m
Length of wire, L = 11.2
Young modulus of steel, 
The young modulus of a wire is given by :





So, the wire will stretch 0.034 meters. Hence, this is the required solution.
Convection is the rise of hot air and the drop of cold air due to a large amount of molecules being moved usually in gas form.\
