Apa Jawaban Nomor 7 Soal Fisika Bikin Sakit Kepala

[tex]lo = 2m = 2000mm \\ lt = lo(1 + \alpha \times delta \: t) \\ lt = 2000(1 + 9 \times {10}^{ - 6} \times (40 - 20)) \\ lt = 2000(1 + 9 \times {10}^{ - 6} \times \: 20) \\ lt = 2000(1.00018) \\ lt = 2000.36 \\ 2000.36 - 2000= 0.36mm[/tex]

Maaf kalo salah, semoga membantu
