Kerjakanlah soal-soal berikut sebagai latihan  dalam persiapan menghadapi ujian nasional, khususnya untuk Mata Pelajaran IPA Fisika SMP

• 1.

### Perhatikan gambar! Hasil pengukuran diameter suatu benda dengan menggunakan mikrometer sekrup adalah ...

• A.

4,55 mm

• B.

4,60 mm

• C.

4,62 mm

• D.

4,65 mm

D. 4,65 mm
Explanation
The correct answer is 4,65 mm.

• 2.

### 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

D. 1,0 gram/cm3
Explanation
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.

### Rina sedang memasak air pada sebuah panci. Setelah mendidih ternyata ada air yang meluap dari panci. Peristiwa tersebut membuktikan bahwa ...

• 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

A. Pemuaian air lebih besar daripada pemuaian panci
Explanation
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.

### 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

C. 22600 Joule
Explanation
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.

### 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

C. 2 dan 4
Explanation
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:

• 6.

• A.

2700 N/m2

• B.

900 N/m2

• C.

300 N/m2

• D.

270 N/m2

C. 300 N/m2
• 7.

### Perhatikan gambar berikut! Dari gambar di atas, perubahan bentuk energi yang sama ditunjukkan oleh gambar nomor ...

• A.

1, 2, dan 3

• B.

1, 2, dan 4

• C.

1, 3, dan 4

• D.

2, 3, dan 4

C. 1, 3, dan 4
Explanation
The correct answer is 1, 3, and 4. From the given image, it can be observed that the energy transformation is shown in these three images. However, without the image provided, it is difficult to provide a specific explanation for each image.

Rate this question:

• 8.

• A.

35 J

• B.

65 J

• C.

70 J

• D.

130 J

C. 70 J
Explanation
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.

### Perhatikan gambar berikut! Dari gambar di atas, pesawat sederhana yang tergolong bidang miring adalah ..

• A.

1 dan 2

• B.

1 dan 4

• C.

2 dan 3

• D.

2 dan 4

B. 1 dan 4
Explanation
Based on the given image, the inclined planes can be identified as 1 and 4. Plane 1 is inclined because it is sloping upwards from left to right, and plane 4 is inclined because it is sloping downwards from left to right. Therefore, the correct answer is 1 and 4.

Rate this question:

• 10.

### Gelombang air laut disajikan seperti gambar berikut! Dalam selang waktu tertentu terjadi gelombang air laut seperti pada gambar. Jika cepat rambat gelombang air laut 2 m/s, maka frekuensi gelombangnya adalah ...

• A.

0,3 Hz

• B.

0,5 Hz

• C.

3,0 Hz

• D.

4,0 Hz

B. 0,5 Hz
