Correct Answer
B. Sesuatu yang dapat diukur nilainya dan dapat dihitung sertaExplanation
The correct answer is "Sesuatu yang dapat diukur nilainya dan dapat dihitung serta". This answer states that a "besaran" is something that can be measured and quantified, implying that it has a numerical value that can be calculated. This definition aligns with the concept of "besaran" in physics, which refers to measurable quantities such as length, time, mass, and temperature.Rate this question:

Besaran secara garis besar dibagi menjadi
- A.
Besaran primer dan besaran turunan
- B.
Besaran Pokok dan besaran sekunder
- C.
Besaran Turunan dan Besaran sekunder
- D.
Besaran Pokok dan besaran turunan
Correct Answer
D. Besaran Pokok dan besaran turunanExplanation
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.Rate this question:

Kelompok besaran turunan di bawah ini yang diturunkan hanya dari besaran panjang adalah.....
- A.
Luas dan Volume
- B.
Volume dan Percepatan
- C.
Kecepatan dan Percepatan
- D.
Luas dan Kecepatan
Correct Answer
A. Luas dan VolumeExplanation
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.Rate this question:

Rumus kecepatan adalah v = jarak/waktu, maka dimensinya adalah..
- A.
[L]2
- B.
[M][L][T]-2
- C.
[L]3
- D.
[L][T]-1
Correct Answer
D. [L][T]-1Explanation
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.Rate this question:

Rumus percepatan adalah a= kecepatan / waktu, maka dimensinya adalah..........
- A.
[L][T]-2
- B.
[M][L][T]-2
- C.
[L]3
- D.
[L][T]-1
Correct Answer
A. [L][T]-2Explanation
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.Rate this question:

Satuan SI untuk suhu adalah
- A.
Celcius
- B.

- D.
Kelvin
Correct Answer
D. KelvinExplanation
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.Rate this question:

- B.
(6.75 ± 0.01) cm
- C.
(6.75 ± 0.2) cm
- D.
(6.75 ± 0.1) cm
Correct Answer
A. (6.75 ± 0.05) cmExplanation
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.Rate this question:

Masa jenis minyak adalah 800 kg/m3, jika di ubah kesatuan CGS (Centi Gram Sekon) nilainya menjadi …..
- A.

- B.
80 g/cm3
- C.
8 g/cm3
- D.
800 g/cm3
Correct Answer
A. 0.8 g/cm3Explanation
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.Rate this question:

- D.
[L][T]-1
Correct Answer
B. [M][L][T]-1Explanation
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.Rate this question:
