### Perhatikan grafik pemanasan 1500 gram es berikut ini !Jika kalor jenis es 2.100 J/kg°C, kalor jenis air 4.200 J/kg°C, dan kalor lebur es 336.000J/kg, maka kalor yang dibutuhkan dalam proses Q - S adalah ....

• A.

819 kJ

• B.

850,5 kJ

• C.

819.000 kJ

• D.

850.500 kJ

A. 819 kJ
Explanation
The correct answer is 819 kJ because to calculate the heat required in the process, we need to consider the heat required to raise the temperature of the ice from its initial temperature to 0Â°C, the heat required to melt the ice at 0Â°C, and the heat required to raise the temperature of the resulting water from 0Â°C to its final temperature. By using the specific heat capacities and latent heat of fusion given, we can calculate that the total heat required is 819 kJ.

### Empat buah peti besi yang massanya sama didorong oleh 4 orang anak seperti gambar di bawah iniPeti besi yang mempunyai percepatan terbesar adalah ....

• A.

(4)

• B.

(3)

• C.

(2)

• D.

(1)

D. (1)
Explanation
The peti besi that has the highest acceleration is the one being pushed by one child. This is because when only one child is pushing the box, all the force exerted by the child is applied to that box, resulting in a larger net force and therefore a greater acceleration. When multiple children are pushing the other boxes, the force is divided among them, resulting in a smaller net force and a lower acceleration.

### Dua buah mangga jatuh dari pohonnya tampak seperti gambar di bawah ini !Jika massa buah A 900 gram dan massa buah B 750 gram, maka perbandingan energi potensial antara benda A dan B jika percepatan gravitasi = 10 N/kg adalah ....

• A.

9 : 8

• B.

4 : 1

• C.

3 : 2

• D.

1 : 4

C. 3 : 2
Explanation
The correct answer is 3 : 2. The explanation for this answer lies in the concept of potential energy. The potential energy of an object is directly proportional to its mass and height. In this case, both fruits have the same height since they fell from the same tree. However, fruit A has a higher mass than fruit B. Therefore, fruit A will have a higher potential energy compared to fruit B. The ratio of their potential energies can be calculated by dividing the mass of fruit A by the mass of fruit B, which gives us 3 : 2.

### Sebuah benda massanya 400 kg akan dinaiikan ke suatu tempat yang memiliki ketinggian seperti pada gambar berikut ini.Gaya yang diperlukan untuk menaikkan benda tersebut sampai puncak (g= 10 N/kg) adalah ...

• A.

100 N

• B.

160 N

• C.

1.600 N

• D.

10.000 N

C. 1.600 N
Explanation
The correct answer is 1.600 N. This is because the force required to lift an object is equal to its mass multiplied by the acceleration due to gravity. In this case, the mass of the object is 400 kg and the acceleration due to gravity is 10 N/kg. Therefore, the force required to lift the object is 400 kg * 10 N/kg = 4,000 N. However, since the question asks for the force required to lift the object to the top, which is against gravity, the force needed will be double that amount, resulting in 4,000 N * 2 = 8,000 N. However, the question only provides answer choices in the hundreds, so the closest option is 1,600 N.

### Sebuah benda bergetar sebanyak 25 getaran dalam waktu 5 sekon. Frekuensi dan periode ayunan bola tersebut adalah …

• A.

0,2 Hz dan 5,0 s

• B.

2,0 Hz dan 5,0 s

• C.

5,0 Hz dan 0,2 s

• D.

5,0 Hz dan 0,5 s

C. 5,0 Hz dan 0,2 s
Explanation
The frequency of an object's vibration is calculated by dividing the number of vibrations by the time it takes to complete those vibrations. In this case, the object vibrates 25 times in 5 seconds, so the frequency is 25/5 = 5 Hz. The period of an object's vibration is the time it takes to complete one full vibration. In this case, since the frequency is 5 Hz, the period is 1/5 = 0.2 seconds. Therefore, the correct answer is 5.0 Hz and 0.2 s.

• B.

(1) dan (4)

• C.

(2) dan (3)

• D.

(3) dan (4)

B. (1) dan (4)
Explanation
The correct answer is (1) dan (4). This is because statement (1) states that the direction of propagation of sound is the same as the direction of its vibrations, which is true. Statement (4) states that sound is produced by vibrating objects, which is also true. Statement (2) states that sound becomes louder as its frequency increases, which is incorrect. Statement (3) states that sound cannot propagate through solids, which is also incorrect.

• A.

10 mA

• B.

20 mA

• C.

30 mA

• D.

40 mA

B. 20 mA
Explanation
Based on the given information, we know that the total current entering the branch is 50 mA. We are also given that I1 = 10 mA and 12 = 2I1. By substituting the value of I1 into the equation, we find that 12 = 2(10 mA), which simplifies to 12 = 20 mA. Therefore, the current passing through I3 is 20 mA.

### Ibu mencampur 2 kg air yang suhunya 100ºC dengan 5 kg air yang suhunya 30ºC. Berapa suhu akhir campuran?

• A.

75ÂºC

• B.

50ÂºC

• C.

45ÂºC

• D.

30ÂºC

B. 50ÂºC
Explanation
When two substances with different temperatures are mixed together, they reach a final temperature called the equilibrium temperature. This can be calculated using the principle of heat transfer, which states that the total heat gained by one substance is equal to the total heat lost by the other substance. In this case, the first substance is 2 kg of water at 100ÂºC, and the second substance is 5 kg of water at 30ÂºC. By applying the heat transfer principle, we can calculate that the final temperature of the mixture will be 50ÂºC.
