Berikut adalah besaran turunan, kecuali ...
- A.
Luas
- B.
Massa jenis
- C.
Massa
- D.
Kecepatan
- E.
Percepatan
Correct Answer
C. MassaExplanation
Massa adalah besaran turunan yang tidak termasuk dalam daftar tersebut. Luas, massa jenis, kecepatan, dan percepatan semuanya adalah besaran turunan yang dapat dihitung atau diukur berdasarkan besaran dasar seperti panjang, waktu, dan massa. Massa, di sisi lain, adalah besaran dasar yang tidak dihitung atau diukur berdasarkan besaran lainnya.Rate this question:

Satuan dari besaran gaya adalah ....
- A.
Kg.m/s2
- B.
Kg.m/s
- C.
Kg.m
- D.
Kg/m.s2
- E.
Kg/m.s
Correct Answer
A. Kg.m/s2Explanation
The correct answer is kg.m/s2. The unit of force is derived from Newton's second law of motion, which states that force is equal to mass multiplied by acceleration. The unit for mass is kilogram (kg) and the unit for acceleration is meters per second squared (m/s2). Therefore, the unit of force is kg.m/s2.Rate this question:

Penggaris mistar
- B.
Meteran
- C.
Jangka sorong
- D.
Mikrometer
- E.
Neraca ohaus
Correct Answer
E. Neraca ohausExplanation
The question asks for an exception among the given options, which are all measuring tools for length. The exception is "Neraca ohaus" which is a weighing scale, not a measuring tool for length.Rate this question:

Sebuah Jangka sorong menunjukkan pada skala Utama 2,4 cm dan angka pada skala Nonius yang segaris dengan salahsatu garis skala utama adalah 5, maka hasil pembacaan akhir pengukuran adalah ....
- A.
2,90 CM
- B.
2,54 CM
- C.
2,45 CM
- D.
2,40 CM
- E.
2,04 CM
Correct Answer
C. 2,45 CMExplanation
The correct answer is 2,45 CM. This is because the main scale reading is 2,4 cm and the vernier scale reading is 0,05 cm (which is the value aligned with one of the main scale lines). Adding these two readings together gives a final measurement of 2,45 cm.Rate this question:

Jika pada skala Nonius Jangka sorong terbaca 0,03 cm dan skala Utama terbaca 1 cm , maka pembacaan hasil akhir alat tersebut adalah ....
- A.
1,30 CM
- B.
1,13 CM
- C.
1,11 CM
- D.
1,03 CM
- E.
1,00 CM
Correct Answer
D. 1,03 CMExplanation
The correct answer is 1,03 CM. This is because the Nonius scale reads 0.03 cm and the Main scale reads 1 cm. To find the final reading, we add the values from both scales together, which gives us 1.03 cm.Rate this question:

Sebuah mikrometer pada skala Utama terbaca 4 mm, dan angka pada skala Nonius terbaca 15, maka hasil akhir pembacaan skala alat ukur adalah ....
- A.
4,015 mm
- B.
4,15 mm
- C.
4,51 mm
- D.
4,55 mm
- E.
4,56 mm
Correct Answer
B. 4,15 mmExplanation
The main scale of the micrometer reads 4 mm, and the vernier scale (Nonius) reads 15. To find the final reading, we add the main scale reading to the vernier scale reading multiplied by the least count. The least count is the difference between one main scale division and one vernier scale division. In this case, the least count is 0.01 mm (1 main scale division = 0.1 mm and 10 vernier scale divisions = 0.1 mm). Therefore, the final reading is 4 mm + (15 * 0.01 mm) = 4.15 mm.Rate this question:

Dimensi dari besaran gaya adalah ....
- A.
M.L/ T2
- B.
M.L/T
- C.
M.L.T2
- D.
M.L.T3
- E.
M.L/T3
Correct Answer
A. M.L/ T2Explanation
The dimension of force is given by the formula M.L/T2, where M represents mass, L represents length, and T represents time. This formula indicates that force is measured in terms of the product of mass and length divided by the square of time.Rate this question:

Besaran energi potensial memiliki dimensi yang sama dengan besaran ....
- A.
Massa jenis
- B.

- E.
Gaya
Correct Answer
C. UsahaExplanation
The dimension of potential energy is the same as work done. Work is defined as the transfer of energy resulting from a force applied over a distance. Therefore, the dimension of potential energy is the same as work, which is measured in joules (J).Rate this question:

Sebuah segiempat panjangnya 10,0 cm dan lebarnya 5,0 cm, dengan menggunakan aturan bilangan penting maka luas segiempat adalah ....
- A.
5 CM2
- B.
5,0 CM2
- C.
50 CM2
- D.
50,0 CM2
- E.
50,00 CM2
Correct Answer
C. 50 CM2Explanation
The correct answer is 50 CM2 because when using the rule of significant figures, the result should be rounded to the same number of decimal places as the measurement with the fewest decimal places. In this case, both measurements have zero decimal places, so the answer should also have zero decimal places. Therefore, the correct answer is 50 CM2.Rate this question:

- B.
2 angkapenting, 3 angkapenting, dan 3 angkapenting
- C.
3 angkapenting, 2 angkapenting, dan 3 angkapenting
- D.
2 angkapenting, 2 angkapenting, dan 3 angkapenting
- E.
3 angkapenting, 3 angkapenting, dan 2 angkapenting
Correct Answer
A. 3 angkapenting, 3 angkapenting, dan 3 angkapentingExplanation
The given measurements have three significant figures each. In the first measurement, 35.0 cm, the zero after the decimal point indicates that it is significant. In the second measurement, 20.5 cm, both the zero after the decimal point and the trailing zero are significant. In the third measurement, 0.501 cm, all the digits are significant. Therefore, the correct answer is "3 angkapenting, 3 angkapenting, dan 3 angkapenting."Rate this question:
