Besaran secara garis besar dibagi menjadi
Correct Answer
D. Besaran Pokok dan besaran turunan
Explanation
The correct answer is "Besaran Pokok dan besaran turunan". This is because the question is asking for a general division of quantities, and "Besaran Pokok dan besaran turunan" is the most accurate and comprehensive division. "Besaran primer dan besaran turunan" is not a commonly used division of quantities. "Besaran Pokok dan besaran sekunder" is not a widely recognized division. "Besaran Turunan dan Besaran sekunder" is not a commonly used division and does not cover all types of quantities.

Kelompok besaran turunan di bawah ini yang diturunkan hanya dari besaran panjang adalah.....
Correct Answer
A. Luas dan Volume
Explanation
The correct answer is "Luas dan Volume". Both area (luas) and volume are derived from the base quantity of length (panjang). Area is derived by multiplying two lengths together, while volume is derived by multiplying three lengths together. The other options, such as velocity (kecepatan) and acceleration (percepatan), are not derived solely from length and involve other base quantities like time.

Explanation
The conversion from km/h to m/s can be done by dividing the value in km/h by 3.6. In this case, when the given speed of 72 km/h is divided by 3.6, the result is 20 m/s.
13.
Dimensi Luas adalah.................
Correct Answer
D. [L][T]-1
Explanation
The given answer [L][T]-1 represents the dimensions of area, which is the product of length and time to the power of -1. This indicates that area is measured in terms of length squared divided by time.
14.
Rumus kecepatan adalah v = jarak/waktu, maka dimensinya adalah..
Correct Answer
D. [L][T]-1
Explanation
The correct answer is [L][T]-1. The formula for velocity is v = distance/time, where distance is measured in meters (L) and time is measured in seconds (T). When we divide distance by time, the units cancel out and we are left with meters per second, which is the unit for velocity. Therefore, the dimensions for velocity are [L][T]-1.
15.
Ketidakpastian alat ukur penggaris adalah ….cm
Correct Answer
A. 0.005
Explanation
The correct answer is 0.005 because it is the smallest value among the given options. This suggests that the measurement uncertainty of the ruler is 0.005 cm, indicating that there may be slight variations or errors in the measurements taken with this ruler.
16.
Rumus percepatan adalah a= kecepatan / waktu, maka dimensinya adalah..........
Correct Answer
A. [L][T]-2
Explanation
The given formula for acceleration is a = velocity / time. The dimensions of acceleration can be determined by analyzing the units of the variables involved. The unit of velocity is [L][T]-1 (length/time) and the unit of time is [T] (time). Dividing the unit of velocity by the unit of time gives us [L][T]-1 / [T], which simplifies to [L][T]-2. Therefore, the dimensions of acceleration are [L][T]-2.

7.5 l = …...ml
Correct Answer
C. 7500
Explanation
7.5 liters is equal to 7500 milliliters. This is because there are 1000 milliliters in 1 liter, so to convert liters to milliliters, we multiply by 1000. Therefore, 7.5 multiplied by 1000 equals 7500 milliliters.
20.
Satuan SI untuk suhu adalah
Correct Answer
D. Kelvin
Explanation
The correct answer is Kelvin because Kelvin is the SI unit of temperature. It is an absolute temperature scale where 0 Kelvin represents absolute zero, the lowest possible temperature. Kelvin is widely used in scientific and engineering applications, especially in thermodynamics and physics. It is preferred over other temperature scales like Celsius, Reamur, and Rankine because it is based on the fundamental properties of matter and does not have negative values.

Hasil pengukuran dari suatu benda dengan penggaris menunjukkan 6,75 cm . Maka penulisan yang benar adalah…....
Correct Answer
A. (6.75 ± 0.05) cm
Explanation
The correct answer is (6.75 ± 0.05) cm. This is because the measurement of the object using the ruler is given as 6.75 cm. The ± symbol indicates the uncertainty or margin of error in the measurement. The value of ±0.05 cm suggests that the actual measurement could be 0.05 cm higher or lower than the recorded value of 6.75 cm. This range of uncertainty is appropriate for the given measurement.

The correct answer is 3.1 because it is the only value among the given options that matches the measurement indicated by the ruler. The other values (5.1, 3, and 5.2) do not align with the measurement provided.
27.
Hasil baca alat ukur penggaris berikut ini adalah…....cm
Correct Answer
D. (3.0 ± 0.01)
Explanation
The correct answer is (3.0 ± 0.01). This is because the answer represents the measurement with the highest precision. The value of 3.0 indicates the best estimate of the measurement, while the uncertainty of 0.01 indicates the range within which the true value is likely to fall. This level of uncertainty is smaller compared to the other options, making (3.0 ± 0.01) the most accurate and precise measurement.

Masa jenis minyak adalah 800 kg/m3, jika di ubah kesatuan CGS (Centi Gram Sekon) nilainya menjadi …..
Correct Answer
A. 0.8 g/cm3
Explanation
The given question asks for the value of the density of the oil in CGS units. The density of the oil is given as 800 kg/m3. To convert this to CGS units, we need to convert the mass from kilograms to grams and the volume from cubic meters to cubic centimeters. Since 1 kg = 1000 g and 1 m3 = 1000000 cm3, the density in CGS units becomes 800 g/1000000 cm3 = 0.8 g/cm3.

Momentum (P) memiliki rumus, P = masa x kecepatan, maka dimensi yang benar adalah …..
Correct Answer
B. [M][L][T]-1
Explanation
The correct answer [M][L][T]-1 represents the correct dimensions for momentum. The formula for momentum is mass multiplied by velocity. Mass has dimensions [M], velocity has dimensions [L][T]-1, and when multiplied together, the dimensions become [M][L][T]-1. This represents the correct dimensions for momentum.
