L1 = 1 m = 100 cm
T1 = 25 derajat celcius
α = 0,000017 /derajat celcius
T2 = 50 derajat celcius
ditanyakan : L2 =........?
JAWAB :
L2 = L1 { 1+α(T2-T1)}
100 { 1+0,000017(50-25)}
100 { 1 + 0,000017 × 25 }
100 { 1 + 0,000425 }
(100×1) + ( 100×0,000425)
100+0,0425
100,0425 Jadi, jawabannya b. 100,0425 semoga benar, maaf derajat celciusnya gk bisa di lambangin.
