tolong bantu jawabnya dong, besok udah mau du kumpul

1.Dik:n=90
t=30s
Dit:f=...?
Jawab:
[tex]f = \frac{n}{t} \\ = \frac{90}{30s} \\ = 3hz[/tex]

Dik:t=30s
n=90
Dit:T=...?
Jawab:
[tex]T = \frac{t}{n} \\ = \frac{30s}{90} \\ = 0.3s[/tex]

2.Dik:t=6s
f=10hz
Dit:n=...?
Jawab:
[tex]n = f \times t \\ = 10hz \times 6s \\ = 60[/tex]

Dik:t=6s
f=10hz
Dit:T=...?
Jawab:
[tex]T = \frac{t}{n} \\ = \frac{6s}{10hz} \\ = 0.6hz[/tex]


3.Dik:n=600
f=15hz
Dit:t=...?
Jawab:
[tex]t = \frac{n}{f} \\ = \frac{600}{15hz} \\ = 40s[/tex]

Dik:t=40s
f=15hz
Dit:T=...?
Jawab:
[tex]T = \frac{t}{n} \\ = \frac{40s}{15hz} \\ = 2.7s[/tex]


4.Dik:t=60s
T=0,2s
Dit:n=...?
Jawab:
[tex]n = \frac{t}{T} \\ = \frac{60s}{0.2s} \\ = 300 [/tex]

Dik:n=300
t=60s
Dit:f=...?
Jawab:
[tex]f = \frac{n}{t} \\ = \frac{300}{60s} \\ = 5hz[/tex]
