    balok tersebut kemudian di tumpuk dengan balok lainbermassa 2 kg. kecepatan sistem balok dengan gaya F yang sama menjadi....

    • A.

      1,0 m\s2

    • B.

      1,2 m\s2

    • C.

      1,5 m\s2

    • D.

      2,0 m\s2

    Correct Answer
    B. 1,2 m\s2
    Explanation
    When the block is stacked with another block of mass 2 kg, the total mass of the system becomes higher. According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Since the force applied is the same, the higher mass of the system will result in a lower acceleration. Therefore, the correct answer is 1.2 m/s^2.

    Rate this question:

  • 10. 

    energi kinetik saat kelapa yang massanya 2kg berada pada ketinggian 4m dari tanah adalah... (g=10m\s2)

    • A.

      80 j

    • B.

      180 j

    • C.

      320 j

    • D.

      480 j

    Correct Answer
    A. 80 j
    Explanation
    The potential energy of an object at a certain height is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height. In this case, the mass is 2kg, the height is 4m, and the acceleration due to gravity is 10m/s^2. Plugging these values into the formula, we get PE = 2kg * 10m/s^2 * 4m = 80J. Therefore, the correct answer is 80J.

    • D.

      Balok (1) : 500kg\m : balok (2) : 550kg\m3 : balok (3) : 650kg\m3 : zat cair : 1.100kg\m3

    Correct Answer
    A. Balok (1) : 600kg\m : balok (2) : 400kg\m3 : balok (3) : 200kg\m3 : zat cair : 800kg\m3
    Explanation
    The given answer is correct because in order for the blocks to be in the position shown in the picture, the density of the liquid must be greater than the density of the blocks. In this case, the density of the liquid is 800 kg/m^3, which is greater than the densities of the blocks (600 kg/m^3, 400 kg/m^3, and 200 kg/m^3). This density difference causes the blocks to float in the liquid, with the lighter block (200 kg/m^3) floating higher than the heavier blocks.

    • D.

      (4) dan (2)

    Correct Answer
    C. (3) dan (2)
    Explanation
    The explanation for the correct answer (3) and (2) is that the swing with the longest period will have the slowest oscillation, while the swing with the shortest period will have the fastest oscillation. Looking at the options, the swing in picture (3) appears to have a longer length, which would result in a longer period. Similarly, the swing in picture (2) appears to have a shorter length, which would result in a shorter period. Therefore, (3) and (2) are the swings with the largest and smallest periods respectively.

    • D.

      Nyata,tegak,lebih besar dari bayangan semula

    Correct Answer
    B. Maya,terbalik,lebih kecil dari bayangan semula
    Explanation
    When an object is moved 10cm away from a lens, a virtual, inverted, and smaller image is formed. This is because when an object is moved farther away from a lens, the image formed becomes smaller in size and is formed on the same side as the object, which is virtual. Additionally, the image formed by a lens is always inverted.

    jika bagian Pada rheostat di geser ke kiri,maka nyala lampu menjadi...

    • A.

      Makin redup karena tegangan listrik pada lampu semakin kecil

    • B.

      Tetap karena sumber tegangan tidak berubah

    • C.

      Semakin terang karena alus listrik yang mangalir semakin besar

    • D.

      Makin redup karena hambatan rheostat semakin besar

    Correct Answer
    A. Makin redup karena tegangan listrik pada lampu semakin kecil
    Explanation
    When the rheostat is moved to the left, the resistance of the rheostat increases. As a result, the voltage across the lamp decreases because the total voltage is divided between the lamp and the increased resistance of the rheostat. A decrease in voltage leads to a decrease in the brightness of the lamp, hence the answer "makin redup karena tegangan listrik pada lampu semakin kecil" (dimmer because the electric voltage on the lamp becomes smaller).

    Rate this question:

  • 23. 

    jika transformator pada gambar merupakan transformator ideal,besar tegangan listrik yang terjadi pada lampu adalah

    • C.

      720 V

    • D.

      880 V

    Correct Answer
    A. 55 V
    Explanation
    If the transformer in the picture is an ideal transformer, the voltage across the lamp would be 55 V.

      (6) dan (8)

    Correct Answer
    B. (2) dan (7)
    Explanation
    The correct answer is (2) dan (7). In freshwater ecosystems, biotic components refer to living organisms that inhabit or depend on the water. Option (2) and (7) are the only choices that represent living organisms typically found in freshwater ecosystems. Therefore, they are the correct answer.

    Correct Answer
    A. Berkembang biak,membutuhkan makanan,tumbuh dan berkembang
    Explanation
    The correct answer is "berkembang biak, membutuhkan makanan, tumbuh dan berkembang". This answer describes the characteristics of living organisms. "Berkembang biak" means reproducing, which is a characteristic of living organisms. "Membutuhkan makanan" means needing food, which is also a characteristic of living organisms. "Tumbuh" means growing, and "berkembang" means developing, which are both processes that living organisms undergo. Therefore, this answer accurately describes the characteristics of living organisms.
