a°F --> °C = 5/9 × (a-32)
95°F = 5/9 × (95-32)
= 35°C
5°F = 5/9 × (5-32)
= -15°C
10. Ph = pgh
= 1000 × 9,8 × (0,8-0,2)
( perhatikan satuan hrs dlm mks )
= 5880 N/m²

keuntungan mekanik = 180 : 20 = 9
keuntungan mekanik = beban : kuasa
9 = 360 : kuasa
kuasa = 40 N
jawaban: C
6.
1-2-3 mrpk ½gelombang
maka 1 gelombang perlu waktu (T) = 2×0,2 = 0,4s
f = 1/T = 1/0,4 = 2,5 Hz
amplitudo adl dari 2 ke 3,
A =16cm/2 = 8cm
