    • D.

      3 dan 4

    Correct Answer
    D. 3 dan 4
    Explanation
    The activities described in options 3 and 4 are consistent with Newton's Third Law of Motion. In option 3, the action of the ship's propeller pushing water backward causes an equal and opposite reaction, propelling the ship forward. In option 4, the action of the bullet being shot forward results in an equal and opposite reaction, pushing the gun backward. These examples demonstrate the principle that every action has an equal and opposite reaction, as stated in Newton's Third Law.

    • B.

      1 dan 3

    • C.

      2 dan 3

    • D.

      3 dan 4

    Correct Answer
    A. 1 dan 2
    Explanation
    The correct answer is 1 and 2. This is because both statements 1 and 2 demonstrate the application of Newton's First Law of Motion, also known as the law of inertia. In statement 1, when the bus suddenly brakes, the standing passenger falls forward due to their inertia. In statement 2, when riding a motorcycle, the rider feels a backward push as the motorcycle accelerates forward, again due to inertia. Both situations can be explained by Newton's First Law, which states that an object will remain at rest or in uniform motion unless acted upon by an external force.

    Dua benda A dan B memiliki massa yang sama. Benda A bergerak dengan energi kinetik 4 joule dan B dengan energi kinetik 16 joule. Perbandingan kecepatan benda A dengan benda B adalah ....

    • A.

      1 : 2

    • B.

      1 : 4

    • C.

      2 : 1

    • D.

      4 ; 1

    Correct Answer
    A. 1 : 2
    Explanation
    The ratio of the kinetic energies of objects A and B is 1:4. Since kinetic energy is directly proportional to the square of the velocity, the ratio of their velocities would be the square root of the ratio of their kinetic energies. Taking the square root of 1:4 gives us 1:2, which means that the ratio of the velocities of objects A and B is 1:2.

    Mobil A massanya sama dengan mobil B. kedua mobil bergerak lurus sehingga energi kinetik mobil A = 9 kali dari energi kinetik mobil B. Kecepatan mobil A dibanding mobil B adalah ....

    • A.

      1 : 3

    • B.

      1 : 9

    • C.

      3 : 1

    • D.

      9 : 1

    Correct Answer
    C. 3 : 1
    Explanation
    The question states that the mass of car A is the same as car B, and both cars are moving in a straight line. It also states that the kinetic energy of car A is 9 times greater than the kinetic energy of car B. The formula for kinetic energy is 1/2 * mass * velocity^2. Since the mass is the same for both cars, the only way for car A to have 9 times greater kinetic energy is if its velocity is 3 times greater than car B. Therefore, the ratio of the velocity of car A to car B is 3 : 1.

    Perhatikan pernyataan berikut!1) mengukur kekuatan bunyi2) mengukur jarak antar tebing3) mendeteksi janin dalam kandungan dengan USG4) menentukan tinggi rendahnya nadaPernyataan yang menunjukkan pemanfaatan bunyi pantul adalah ....

    • A.

      1 dan 2

    • B.

      1 dan 4

    • C.

      2 dan 3

    • D.

      3 dan 4

    Correct Answer
    C. 2 dan 3
    Explanation
    Pernyataan yang menunjukkan pemanfaatan bunyi pantul adalah mengukur kekuatan bunyi (pernyataan 1) dan mendeteksi janin dalam kandungan dengan USG (pernyataan 3). Mengukur kekuatan bunyi melibatkan pantulan bunyi dari suatu objek, seperti dalam penggunaan sonar atau radar. Mendeteksi janin dalam kandungan dengan USG juga melibatkan pantulan bunyi dari jaringan tubuh. Oleh karena itu, pernyataan 2 dan 3 adalah jawaban yang tepat.

    Seseorang berteriak di depan mulut gua. 1,5 detik setelah berteriak, terdengar kembali gema dari dalam gua. Jika cepat rambat bunti di udara 332 m/s, kedalaman gua tersebut adalah ....

    • A.

      996 m

    • B.

      498 m

    • C.

      249 m

    • D.

      124,5 m

    Correct Answer
    C. 249 m
    Explanation
    The speed of sound in air is given as 332 m/s. Since the sound takes 1.5 seconds to travel from the person to the cave and back, we can calculate the distance traveled by multiplying the speed of sound by the time taken: 332 m/s * 1.5 s = 498 m. However, since the distance traveled is the total distance from the person to the cave and back, we need to divide this by 2 to find the depth of the cave. Therefore, the depth of the cave is 498 m / 2 = 249 m.

    Sebuah kapal memancarkan bunyi ke dasar laut. 2 sekon kemudian terdengar bunyi pantul dari dasar laut. Jika cepat rambat bunyi 1400 m/s di tempat tersebut, maka kedalaman laut adalah ....

    • A.

      700 m

    • B.

      1.050 m

    • C.

      1.400 m

    • D.

      1.800 m

    Correct Answer
    C. 1.400 m
    Explanation
    The time it takes for the sound wave to travel from the ship to the bottom of the sea and back is 2 seconds. Since the speed of sound in water is given as 1400 m/s, we can calculate the distance traveled by multiplying the speed by the time: 1400 m/s * 2 s = 2800 m. However, the distance traveled is only one-way, so we need to divide it by 2 to get the depth of the sea: 2800 m / 2 = 1400 m. Therefore, the depth of the sea is 1400 m.

    Semakin cepat dinamo sepeda berputar, GGL yang dihasilkan semakin ....

    • A.

      Besar, karena medan magnetnya makin kuat

    • B.

      Kecil, karena selang waktu perubahan medan magnet semakin lama

    • C.

      Kecil, karena garis gaya magnet semakin banyak

    • D.

      Besar, karena perubahan garis gaya magnet semakin cepat

    Correct Answer
    D. Besar, karena perubahan garis gaya magnet semakin cepat
    Explanation
    The correct answer is "besar, karena perubahan garis gaya magnet semakin cepat" because when the bicycle dynamo rotates faster, the rate of change of magnetic field lines also increases. This leads to a stronger induced electromotive force (GGL) in the dynamo. Therefore, the GGL produced is larger when the dynamo rotates faster.

    Correct Answer
    C. 2, 4, dan 5
    Explanation
    The correct answer is 2, 4, and 5. This is because asteroids have elliptical and elongated orbits, they are called small planets, and they are made up of rocky materials forming a belt.
