AsruulNomor 8 Diketahui = F₁ = 200 N A₁ = 20 m³ A₂ = 60 m³ Ditanya = F₂..? Jawab = F₁/A₁ = F₂/A₂ F₂ = F₁/A₁ x A₂ = 200/20 x 60 = 600 N Nomor 9 Diketahui = t = 1 sekon n = 2 glombang s = 6 m Ditanya = v..? Jawab = f = n/t = 2/1 = 2 Hz λ = 6/2 = 3 m v = f . λ = 2 x 3 = 6 m/s Nomor 10 Diketahui = n = 1000 getaran t = 1 menit = 60 sekon Ditanya = f..? Jawab = f = n/t = 1000/60 = 16,67 Hz = C karena frekunsi <20 Hz Nomor 11 Diketahui = s = 10 cm s' = 30 cm Ditanya = f..? Jawab = 1/f = 1/s + 1/s' = 1/10 + 1/30 = 3+1/30 = 4/30 = 30/4 = 7,5 cm Nomor 12 Hukum Turunan F = k . Q₁Q₂/r² F ~ k . Q₁Q₂/r² F ~ 1/r² Sehingga F/F' = (r'/r)² F' = (r'/r)² x F = (4r/2r)² x F = (4/2)² F = 2²F = 4F
=200/20=F2/60
F2=20/2×60=600N
9. v=s/t
=6/1=6m/s

11. 1/f=1/s+1/s'=1/10+1/30
=3/30+1/30
1/f =4/30
f=30/4=7,5

menurut q sh gtu
Diketahui = F₁ = 200 N
A₁ = 20 m³
A₂ = 60 m³
Ditanya = F₂..?
Jawab = F₁/A₁ = F₂/A₂
F₂ = F₁/A₁ x A₂
= 200/20 x 60
= 600 N
Nomor 9
Diketahui = t = 1 sekon
n = 2 glombang
s = 6 m
Ditanya = v..?
Jawab = f = n/t
= 2/1
= 2 Hz
λ = 6/2
= 3 m
v = f . λ
= 2 x 3
= 6 m/s
Nomor 10
Diketahui = n = 1000 getaran
t = 1 menit = 60 sekon
Ditanya = f..?
Jawab = f = n/t
= 1000/60
= 16,67 Hz
= C karena frekunsi <20 Hz
Nomor 11
Diketahui = s = 10 cm
s' = 30 cm
Ditanya = f..?
Jawab = 1/f = 1/s + 1/s'
= 1/10 + 1/30
= 3+1/30
= 4/30
= 30/4
= 7,5 cm
Nomor 12
Hukum Turunan
F = k . Q₁Q₂/r²
F ~ k . Q₁Q₂/r²
F ~ 1/r²
Sehingga
F/F' = (r'/r)²
F' = (r'/r)² x F
= (4r/2r)² x F
= (4/2)² F
= 2²F
= 4F
