Answer:
Hi, Im Jenna! Here is ur ansswer Pls mark as braijnliest
Explanation:
solution.
The formula for linear expansivity is
α = (If – If) / If (0f – 0i ) is used to determine the linear expansivity
If – final length,
I – initial length
0f – final tempt.
0i – initial tempt.
(b) (ii)
I = 3 m
0 = 29oC
02 = 41oC
α = 1.0 x 10 k-1
using safety gap = change in length
Δ l = α I Δ Θ
1 x I0-5 x 3.0 x (41 – 29) = 3.6 x 10-3 m = 0.0036
