6. A box of mas 2 kg was released from a helicopter flying horizontally at a speed og 20m/s. find the kinetic energy of the box after 6,5 seconds?
mass = 2 kg
velocity = 20 m/s
time = 6,5 seconds
kinetic energy = ?
kinetic energy = 1/2.m.v^2
kinetic energy = 1/2.2.20^2
kinetic energy = 400 J
kinetic energy after 6,5 seconds :
400 J. 6,5 seconds = 2600 Joule
Answer : 2600 Joule

9. a sound wave travels 4000m inside a medium if travels time is 20sec, decide the speed of sound in that medium
Diketahui :
s = 4.000 m
t = 20 s
Ditanya :
v?
Jawab :
v = [tex] \frac{s}{t} [/tex]
v = [tex] \frac{4.000}{20} [/tex]
v = 200 m/s
10. A ship measures the depth of a marine waters by using a sound device. The sound is fired at the bottom of the waters and 6 seconds later the reflective sound arrives back on the ship. If the speed of the sound in the water is 800 m / s, determine the depth of the water !
we know that
v(velocity)=800 m/s
t(time)=6 second
d=?
to determine the depth we will use the formula
D=v×t/2
d=800×6/2
=2400 m
or 2,4 km
so the depth of the water is 2400 m or 2,4 km

12. A turtle swam 720 metres at a speed of 180 metres per minute. Then, it swam another 960 metres at a speed of 160 metres per minute. What was the turtle's average swimming speed?
Penjelasan dengan langkah-langkah:
720/180= 4 minutes
960/160= 6 minutes
the turtle swam for (720 + 960=) 1680 metres in (4 + 6 =) 10 minutes.
it means it average speed is...
1680/10
= 168metres/minute

18. When plucked, a 0.62m guitar string produces a sound wave with a fundamental frequency of 196Hz. The speed of sound in air is 343m/s. Determine the ratio of the wavelength of the sound wave in air to the wavelength of the waves that travel on the string.
Wavelength of the sound in air: v = f*lambda. You have the speed and the frequency, plug them in.
Wavelength of the sound on the string: The fundamental frequency on a string fixed at both ends (like a guitar string) is such that the length of the string is lambda/2. So lambda = 2*L.

diket:
jarak (s) = 1 km = 1.000 m
waktu (t) = 3 s
ditanya:
kecepatan (v)....?
jawab:
v = s/tv = 1.000 m / 3 s
v = 333,33 m/s
Jadi, kecepatan bunyi di udara adalah 333,33 m/s.
23. a source of sound has 0.4 m wavelength and a frequency of 340 Hz. The speed of the soundat is...(Sebuah sumber bunyi memiliki panjang gelombang 0,4 m dan frekuensi 340 Hz.Cepat rambat bunyi tersebut ialah...)
Diketahui:
λ = 0,4 m
f = 340 Hz
v = ?
Jawab:
v = f λ
v = (340 Hz)(0,4 m)
v = 136 m/s

Penjelasan:
Jawablah pertanyaan-pertanyaan di bawah ini dengan pernyataan BENAR atau
SALAH . Jika jawaban anda BENAR, pilihlah alasannya yang cocok dengan
jawaban anda . Begitu pula jika jawaban anda SALAH, pilihlah alasannya yang
cocok dengan jawaban anda.
1. Dua besaran yang dijumlahkan harus mempunyai dimensi yang sama.
Benar Salah
Alasan :
a. Dua besaran fisika atau lebih dapat dijumlahkan dengan syarat memiliki
dimensi yang sama
b. Untuk dapat menjumlahkan dua besaran fisika atau lebih tidak perlu
memperhatikan dimensinya
2. Dua besaran yang dikalikan harus mempunyai dimensi yang sama
Benar Salah
Alasan :
a. Dua besaran fisika atau lebih dapat dikalikan dengan syarat memiliki dimensi
yang sama
b. Untuk dapat mengalikan dua besaran fisika atau lebih tidak perlu
memperhatikan dimensinya
3. Jika pada suatu saat kecepatan adalah nol, maka percepatan juga harus nol pada saat
itu.
Benar Salah
Alasan :
a. Percepatan adalah rasio perubahan kecapatan ∆v terhadap selang waktu ∆t .
Jika pada suatu saat kecepatan adalah nol, maka ∆v belum tentu nol,
sehingga percepatan belum tentu nol.
b. Percepatan adalah rasio perubahan kecapatan ∆v terhadap selang waktu ∆t .
Jika pada suatu saat kecepatan adalah nol, maka ∆v juga tentu akan nol,
sehingga percepatannya juga pasti nol.
4. Jika percepatan nol, benda tidak akan dapat bergerak.
Benar Salah
Alasan :
a. Percepatan adalah rasio perubahan kecapatan ∆v terhadap selang waktu ∆t .
Suatu benda yang diam berarti kecepatannya nol. Karena itu benda tersebut
memiliki ∆v nol, sehingga percepatannya tentu nol.
b. Percepatan adalah rasio perubahan kecapatan ∆v terhadap selang waktu ∆t .
Jika suatu benda percepatannya nol, maka ∆v juga tentu akan nol, sehingga
benda tidak mengalami perubahan kecepatan atau kecapatannya konstan
5. jika percepatan nol, maka kurva posisi(x) terhadap waktu(t) adalah garis lurus.
Benar Salah
Alasan :
a. Jika kurva posisi(x) terhadap waktu (t) adalah garis lurus, berarti benda
sedang bergerak lurus dengan perubahan posisi dalam selang waktu yang
sama adalah sama. Dengan demikian, ∆v -nya adalah nol dan percepatan juga
berharga nol
b. Jika kurva posisi(x) terhadap waktu (t) adalah garis lurus, berarti benda
sedang mengalami percepatan tetap, sehingga percepatan belum tentu nol
6. Besar atau nilai jumlah dua vektor yang nilainya sama harus lebih besar daripada
besar salah satu vektor.
Benar Salah
Alasan :
a. Jika dua buah vektor tersebut dijumlahkan, berapapun sudut yang diapit oleh
kedua vektor tersebut, maka nilai jumlah dua vektor tersebut pasti lebih besar
daripada salah satu vektornya.
b. Jika dua buah vektor tersebut dijumlahkan dengan sudut apit tertentu, ada
kemungkinan nilai jumlah dua vektor tersebut akan sama dengan nilai
daripada salah satu vektornya.
7. Vektor kecepatan sesaat selalu searah dengan arah gerakan.
Benar Salah
Alasan :
a. Kecepatan sesaat adalah limit dari kecepatan rata-rata (vrata-rata =
t
x
∆
∆
; ∆x =
perpindahan, ∆t = selang waktu) atau v =

dx . Dengan demikian vektor
kecepatan sesaat akan selalu searah dengan gerakan.
b. Kecepatan sesaat adalah limit dari kecepatan rata-rata (vrata-rata =

34. 8The birds ... flying in the sky. *(4 Poin) amareishave
Answer:
The birds are flying in the sky.
[tex]\\[/tex]
EXPLANATIONThe subject of the sentence in your question is plural, so the verb you'll have to choose must be plural. Have is also plural, but the sentence wouldn't make sense if you used it in said sentence instead.
(Subjek kalimat dalam pertanyaan berbentuk jamak, sehingga kata kerja yang akan dipilih harus berbentuk jamak juga. Kata kerja "have" juga berbentuk jamak, tetapi kalimatnya akan menjadi tidak masuk akal bila kata kerja tersebut digunakan dalam kalimatnya.)
By the way, the verb "are" is a simple present tense verb. A simple present tense verb is a verb used to refer to actions or states in the present time.
(Kata kerja "are" merupakan kata kerja dengan penekanan simple present. Kata kerja dengan penekanan simple present digunakan untuk hal-hal yang terjadi pada masa sekarang.)
