Lo= 20 cm
α= 0,000012 /°C
Δt= (t₂-t₁)⇒ 80-15= 65°C
Dit:
Lt=..?
Penye:
Lt= Lo.(1+α.Δt)
Lt= 20×(1+0,000012×65)
Lt= 20×(1+0,00078)
Lt= 20×1,00078
Lt= 20,0156 cm
α = 0,000012 /°C
Δt = 80 - 15 = 65°C
Ditanya = Lt..?
Jawb = Lt = Lo (1 + α . Δt)
= 20 (1 + 0,000012 × 65)
= 20 (1 + 0,00078)
= 20 × 1,00078
= 20,0156 cm
