Sebuah lup berfokus 5 cm digunakan untuk mengamati benda yang panjangnya 4 mm. Panjang bayangan benda apabila mata tidak berakomodasi adalah …
- A.
2,0 cm
- B.
2,4 cm
- C.
20 cm
- D.
24 cm
Correct Answer
A. 2,0 cmExplanation
The given question is about using a 5 cm focal length lens to observe an object that is 4 mm long. The question asks for the length of the shadow when the eye does not accommodate. The length of the shadow can be calculated using the formula: Shadow length = (Object length x Focal length) / Object distance. Since the object distance is not given, we can assume it to be infinity when the eye does not accommodate. Therefore, the shadow length would be 2.0 cm.Rate this question:

Perhatikan gambar! Bandul berayun dari A ke B dalam waktu 0,4 sekon. Frekuensi dan amplitudo ayunan bandul adalah …
- A.
1,6 Hz dan 4 cm
- B.
1,6 Hz dan 8 cm
- C.
0,625 Hz dan 4 cm
- D.
0,625 Hz dan 8 cm
Correct Answer
C. 0,625 Hz dan 4 cmExplanation
The correct answer is 0,625 Hz dan 4 cm. This is because the frequency of a pendulum is calculated by dividing 1 by the time period, which in this case is 0.4 seconds. So, 1/0.4 = 2.5 Hz. However, the question asks for the frequency in Hz, so we need to round it to the nearest decimal place, which is 0.625 Hz. The amplitude of the pendulum swing is given as 4 cm.Rate this question:

Ayah membawa dua karung rambutan menggunakan sepeda motor. Jika berat badan ayah 64 kg dan berat kedua karung rambutan 160 hg dan 0,25 kuintal , berat seluruh beban pada sepeda motor….kg
- A.
105
- B.
906
- C.
960
- D.
1.050
Correct Answer
D. 1.050Explanation
The weight of the father is given as 64 kg. The weight of the two sacks of rambutan is given as 160 hg and 0.25 kuintal. To find the total weight, we need to convert the weight of the sacks to kg. 1 hg is equal to 0.1 kg, so 160 hg is equal to 16 kg. 1 kuintal is equal to 100 kg, so 0.25 kuintal is equal to 25 kg. Adding the weight of the father and the weight of the sacks, we get a total weight of 105 kg. Therefore, the correct answer is 1.050 kg.Rate this question:

Kelipatan persekutuan terkecil ( KPK ) dari 36 dan 96 dalam bentuk faktorisasi adalah …
- A.
22 x 3
- B.
22 x 32
- C.
25 x 3
- D.
25 x 32
Correct Answer
D. 25 x 32Explanation
The smallest common multiple (KPK) of 36 and 96 can be found by factoring both numbers. The prime factorization of 36 is 2^2 x 3^2, and the prime factorization of 96 is 2^5 x 3. To find the KPK, we need to take the highest power of each prime factor. In this case, the highest power of 2 is 2^5 and the highest power of 3 is 3^2. Therefore, the KPK of 36 and 96 is 2^5 x 3^2, which is equal to 25 x 32.Rate this question:

2\frac{7}{12}
- B.
2\frac{1}{2}
- C.
2\frac{5}{12}
- D.
2\frac{1}{3}
Correct Answer
D. 2\frac{1}{3}Explanation
The mother initially had 5/6 liter of cooking oil. She used 0.75 liters to fry fish, leaving her with 5/6 - 0.75 = 2/3 liters of cooking oil. She then bought an additional 2 1/4 liters of cooking oil. To add these fractions, we need to find a common denominator, which is 12. So, 2 1/4 can be written as 9/4. Adding 2/3 and 9/4 gives us (8/12 + 27/12) = 35/12, which can be simplified to 2 11/12. Therefore, the mother now has 2 11/12 liters of cooking oil. However, this is not one of the answer choices. The closest option is 2 1/3, which is approximately equal to 2 4/12. Hence, the correct answer is 2 1/3.Rate this question:
