Question

50,05 cm yaa

tolong vantu dengan cara nya
terima kasih✨

Answer 1

L = l0 (1 + alfa . delta T)
50.05 = 50.00 ( 1 + alfa. (110-10))
50.05 = 50.00 (1 + alfa.100)
50.05 = 50.00 + 5000 alfa
alfa = 50.05 - 50.00/5000
alfa = 0.05/5000 = 0.00001
jadi koefisien muai panjang adalah 0.00001

Answer 2

Lo = 50 cm
Lt = 50,05 cm
delta L = 50,05-50 = 0,05 cm
delta T = 110-10 = 100°C

a = delta L / Lo x delta T
a = 0,05 / 50 x 100
a = 0,05 / 5000
a = 0,00001/°C
