Question

Lupa rumus sama stepnya tolong bantu ya mengerjakan pr saya

Answer 1

Dik = 
D₁ = 6 cm = r₁ = 3 cm = 3×10⁻² m
D₂ = 3 cm = r₂ = 1,5 cm = 1,5×10⁻² m 
v₁ = 1,5 m/s
Dit = v₂
Jwb =
Q₁ = Q₂
A₁.v₁ = A₂.v₂
π.r₁².v₁ = π.r₂².v₂
r₁².v₁=r₂².v₂
(3×10⁻²)².1,5 = (1,5×10⁻²)².v₂
9×10⁻⁴.1,5 = 2,25×10⁻⁴.v₂
1,35×10⁻³ = 2,25×10⁻⁴.v₂
v₂ =6 m/s
