Perhatikan gambar! Jika massa benda 50 gram, maka massa jenis benda tersebut adalah ...
- A.
0,2 gram/cm3
- B.
0,3 gram/cm3
- C.
0,5 gram/cm3
- D.
1,0 gram/cm3
Correct Answer
D. 1,0 gram/cm3Explanation
The correct answer is 1,0 gram/cm3. The density of an object is calculated by dividing its mass by its volume. In this case, the mass of the object is given as 50 grams. Since the volume is not provided, we cannot calculate the exact density. However, the only option that has a density of 1,0 gram/cm3 is the correct answer.Rate this question:

- A.
Pemuaian air lebih besar daripada pemuaian panci
- B.
Pemuaian panci lebih besar daripada pemuaian air
- C.
Pemuaian air lebih kecil daripada pemuaian panci
- D.
Pemuaian air sama dengan pemuaian panci
Correct Answer
A. Pemuaian air lebih besar daripada pemuaian panciExplanation
The fact that the water overflows from the pot after boiling indicates that the expansion of water is greater than the expansion of the pot.Rate this question:

Perhatikan gambar grafik berikut! Jika Massa Air 100 Gram, Kalor Jenis Es 2100 J/Kgoc, Kalor Jenis Air 4200 J/Kgoc, Kalor Lebur Es 340000 J/Kg dan kalor uap air 2260000 J/Kg , maka banyaknya kalor yang diperlukan untuk proses dari D ke E adalah ...
- A.
2100 Joule
- B.
34000 Joule
- C.
22600 Joule
- D.
304000 Joule
Correct Answer
C. 22600 JouleExplanation
The correct answer is 22600 Joule. This is because the question asks for the amount of heat required to go from point D to point E on the graph. From the graph, we can see that this transition corresponds to the phase change from solid ice to liquid water. The heat required for this phase change is known as the heat of fusion, which is given as 340000 J/kg. However, the mass of the substance is given in grams, so we need to convert it to kilograms by dividing by 1000. Therefore, the heat required is (340000 J/kg) * (100 g / 1000) = 34000 J. However, this is the heat required for 1 gram of ice, so we need to multiply by the mass of the substance (100 g) to get the total heat required, which is 34000 J * 100 = 3400000 J.Rate this question:

Perhatikan pernyataan berikut! 1. Buah jeruk dilemparkan ke atas 2. Sepeda motor yang bergerak dengan kecepatan tetap 50 Km/jam 3. Bola volly yang meluncur pada bidang miring 4. Buah mangga yang jatuh dari pohon Dari pernyataan di atas, yang termasuk GLB dan GLBB dipercepat adalah ...
- A.
1 dan 2
- B.
1 dan 3
- C.
2 dan 4
- D.
3 dan 4
Correct Answer
C. 2 dan 4Explanation
The correct answer is 2 and 4. The first statement mentions throwing an orange upwards, which is an example of a free fall motion and not an accelerated motion. The second statement describes a motorcycle moving at a constant speed, which is an example of uniform motion and not an accelerated motion. The third statement mentions a volleyball sliding on an inclined plane, which is an example of an accelerated motion due to the force of gravity. The fourth statement describes a mango falling from a tree, which is also an example of an accelerated motion due to the force of gravity. Therefore, the only statements that describe examples of accelerated motion are 2 and 4.Rate this question:

Beberapa gaya bekerja pada benda seperti gambar berikut! Berdasarkan data pada gambar, usaha yang dilakukan terhadap benda adalah ...
- A.
35 J
- B.
65 J
- C.
70 J
- D.
130 J
Correct Answer
C. 70 JExplanation
Based on the diagram, there are two forces acting on the object: one force of 35 J and another force of 35 J in the opposite direction. Since the forces are in opposite directions, they cancel each other out, resulting in a net force of 0 J. Therefore, no work is done on the object. Hence, the correct answer is 0 J.Rate this question:
