how can you say that Lothal was a prosperous part of Ancient
Answers
Solution:
Here,
R=1Ω,Length=L,Cross sectional area, CSA=A
The formula used is,
R=ρ
AL
⟹ρ AL
=1..........(i)
The new length, L
′
=2L
And new CSA = A
′
So we have,
Volume of the wire= AL
Now after the act of stretching the volume remains constant.
Therefore, AL=A ′
L ′
⟹AL=2LA ′
⟹A ′
= 2A
Now the new resistance of the wire becomes
R
new
=ρ A L ′
⟹R new
=ρ 2A2L
⟹R new
=4ρ ALR new
=4×1 by using equation (i)
Therefore the new resistance is 4Ω
Answer:
The people of Lothal made significant and often unique contributions to human civilisation in the Indus era, in the fields of city planning, art, architecture, science, engineering, pottery, and religion. Their work in metallurgy, seals, beads and jewellery was the basis of their prosperity.
