Question

TOLONG BANTU NOMOR 44 AJA PLEASE INI KELAS 8 KOK SMA/SMK BISA BANTU PLEASE

Answer 1

Panjang gelombang=3/2
=1,5m

f=n/t=2/0,6=3,333Hz
v=lamda/t=1,5/0,6=2,5m/s

Answer 2

N = 2
t = 0.6 s
s = 3 m

a. panjang gel (λ)
λ = s / n = 3 ÷ 2 = 1.5 m

b. frekuensi
f = 1 ÷ 0.6 = 5 per 3 hz

c. cepat rambat (v)
v = λ.f = 1.5 x 5 per 3 = 2.5 m/s^2
