Answer:
324.066096 m.
Explanation:
Given that
height of the tower ,h= 324 m
The increase in temperature ,ΔT = 17°C
We know that coefficient of thermal expansion for steel ,α= 12 x 10⁻⁶ C⁻¹
The increase in height is given as
Δ h = α h ΔT
Now by putting the values in the above equation we get
Δ h= 12 x 10⁻⁶ x 324 x 17 m
Δ h=66096 x 10⁻⁶ m
Δ h=0.066096 m
Therefore the height of the tower become 324.066096 m.
