Answer:
Δ L = 2.57 x 10⁻⁵ m
Explanation:
given,
cross sectional area = 1.6 m²
Mass of column = 26600 Kg
Elastic modulus, E = 5 x 10¹⁰ N/m²
height = 7.9 m
Weight of the column = 26600 x 9.8
= 260680 N
we know,
Young's modulus=
stress =
=
= 162925
strain =
now,
Δ L = 2.57 x 10⁻⁵ m
The column is shortened by Δ L = 2.57 x 10⁻⁵ m
Answer:
0.3405V
Explanation:
#Given a magnetic field of , diameter= 18.5cm(r=9.25cm or 0.0925m), we find the magnetic flux of the loop as:
we can now calculate the induced emf, :
Hence, the induced emf of the loop is 0.3405V
