Benda A bergetar selama 30 s dan menghasilkan 60 getaran . benda B bergetar selama 45 s menghasilkan 150 getaran. perbandingan frekuensi getar A dan B adalah...
siapa yang tau jwabannya sama caranyaa" tolong di bntu yaaa...

frekuensi A = 60/30 = 2 n
frekuensi B = n/t
frekuensi B = 150/45 = 3,33 n
perbandingan frekuensi A & B =
2 : 3,33
BENDA A
t : 30 s --> 60getaran
BENDA B
t : 45 s --> 150 getaran
f : n : t
A = 60 : 30 = 2
B = 150 : 45 = 3,33
A :B
2 : 3,33
