Question

Tolong bantu jawab nomer 3 dan 5 makasih :)

Answer 1

5.A1/A2 x v1
2/0,5 x 1
=4 cm/s

Answer 2

Nomor 3
cari volume airnya dulu
Volume (V) = Luas penampang (A)*Kecepatan air (v)*waktu(t)
V = (2*10⁻² m²) * (2*m*s⁻¹) * (2*60*s)
V = 4,8 m³

masaa air (m) = massa jenis air (ρ) * volume (V)
m = 1000 kg*m⁻³ * 4,8 m³ = 4800 kg

Nomor 5
r1²*v1 = r2²*v2
2²*1 = (1/2)²*v2
v2 = 16 cm/s
