PLEASE HELP MEEEE​

Answer 1

Penyelesaian :

1) ∆L = Lo.α.∆T

∆L = Lo.α.(T1-To)

∆L = 300×0,000009×(250-50)

∆L = 300×0,000009×200

∆L = 0,54 m

2) ∆L = Lo.α.∆T

∆L = Lo.α.(T1-To)

∆L = 300×0,000003×(250-50)

∆L = 300×0,000003×200

∆L = 0,18 m

3) ∆L = Lo.α.∆T

∆L = Lo.α.(T1-To)

∆L = 300×0,000003×(250-50)

∆L = 300×0,000026×200

∆L = 1,56 m
