Soal Ulangan Harian Besaran & Satuan

The given answer is correct because it states that a "besaran" is something that has a value and can be measured. This aligns with the definition of a "besaran" as a physical quantity that can be quantified and compared using a standard unit of measurement. Therefore, the statement is true.

Luas termasuk ke dalam kolompok besaran turunan karena luas merupakan hasil dari perkalian dua besaran pokok, yaitu panjang dan lebar. Jadi, luas tidak dapat diukur secara langsung, tetapi harus dihitung menggunakan rumus luas yang melibatkan besaran pokok panjang.

The correct answer is suhu because temperature is one of the seven base quantities in the International System of Units (SI). It is a fundamental physical quantity that is used to measure the degree of hotness or coldness of an object or a system. Temperature is measured using the Kelvin scale in the SI system.

Momen inersia adalah besaran fisika yang menggambarkan resistansi suatu benda terhadap perubahan gerak rotasinya. Satuan momen inersia adalah kilogram meter persegi (kg m2). Oleh karena itu, pernyataan bahwa momen inersia memiliki satuan kg m2 adalah benar.

The given correct answer is "Salah" because the statement "Besaran Turunan adalah besaran yang sudah disepakati menjadi dasar dari besaran" is incorrect. In physics, "Besaran Turunan" refers to derived quantities, which are obtained from fundamental quantities through mathematical operations. They are not the basis or foundation of other quantities.

The correct answer is 20 m/s. This is because 1 km/h is equal to 0.2778 m/s. So, to convert 72 km/h to m/s, we multiply 72 by 0.2778, which gives us 19.9996. Rounding it off, we get 20 m/s.

Momentum memiliki dimensi yang sama dengan dimensi besaran impuls. Momentum adalah jumlah gerakan suatu benda, yang ditentukan oleh massa dan kecepatannya. Impuls adalah perubahan momentum suatu benda yang dihasilkan oleh gaya yang bekerja padanya. Karena momentum dan impuls memiliki hubungan yang erat, maka dimensi besaran momentum juga sama dengan dimensi besaran impuls.

The statement is correct. The unit of Gas Constant is kg m2/ s2 mol oK.

The correct answer is 2 jam. "Mili sekon" is a unit of time that is smaller than a second. To convert it to hours, we need to divide it by the number of milliseconds in an hour. Since there are 3,600,000 milliseconds in an hour, dividing 72,105 by 3,600,000 gives us approximately 0.02002917 hours, which is equivalent to 2 jam. The other options, "dua jam", "2", and "dua", also represent the same answer.

The statement is incorrect. The correct answer is "Salah" (False). The given statement is about the dimension of specific gravity, which is density divided by the density of water. The dimension of specific gravity is dimensionless, as it is a ratio of two similar quantities. It does not have any dimensions of mass, length, or time.

The given answer is correct because Berat Jenis is a physical quantity that is defined as the ratio of the density of a substance to the density of a reference substance. It is dimensionless and does not have any units. Therefore, the statement that Berat Jenis has units of (kg / m2 s2) is false.

The statement is correct. The dimension of a spring constant is mass (M) divided by time squared (T2). This means that the spring constant represents the stiffness of a spring and is measured in units of force per unit length.

Gravitasi memiliki dimensi L T-2, yang berarti bahwa gravitasi memiliki dimensi panjang per satuan waktu kuadrat. Ini sesuai dengan hukum gravitasi Newton yang menyatakan bahwa gaya gravitasi antara dua objek tergantung pada massa objek-objek tersebut dan jarak di antara mereka. Jadi, gravitasi memiliki dimensi yang sesuai dengan persamaan hukum gravitasi Newton, yang menjelaskan mengapa jawaban yang diberikan adalah benar.

The given statement is incorrect. The dimensions of the gravitational constant, G, are M-1 L3 T-2. The gravitational constant represents the strength of the gravitational force between two objects and is a fundamental constant in physics. It is not expressed in terms of M L-2 T-3.

Gravitasi memiliki dimensi M L2 T-3, yang berarti gravitasi memiliki dimensi massa (M), dimensi panjang kuadrat (L2), dan dimensi waktu pangkat minus tiga (T-3). Ini sesuai dengan hukum gravitasi Newton yang menyatakan bahwa gaya gravitasi antara dua benda bergantung pada massa masing-masing benda dan jarak di antara mereka. Oleh karena itu, jawaban yang benar adalah "Benar".

The correct answer is 0,511 mm.

The question is asking for the conversion of 600 Giga meter to Satuan Astronomi (SA). The correct answer options are "4", "empat", "4 SA", "empat SA", "4 Satuan Astronomi", and "empat satuan astronomi". This means that 600 Giga meter is equal to 4 SA, or in Indonesian, "empat SA" or "empat satuan astronomi".

The question asks for the conversion of 24.106 nanoseconds to microseconds. Since there are 1000 nanoseconds in a microsecond, we can divide 24.106 by 1000 to get the equivalent in microseconds, which is 0.024106 microseconds. However, the given answer is 400, which is incorrect. Therefore, the correct answer is not provided.

The given answer states that 3200 kg/m2 is equal to 3.2 grams/cm2. This is because 1 kg is equal to 1000 grams and 1 m2 is equal to 10000 cm2. Therefore, to convert kg/m2 to grams/cm2, we divide 3200 by 1000 and divide by 10000, which gives us 3.2 grams/cm2.
