### Untuk menimbang beras satu karung digunakan alat yang dinamakan......

• A.

Neraca sama lengan

• B.

Timbangan pegas

• C.

Timbangan mobil

• D.

Timbangan kodok

• E.

Neraca O'hauss

A. Neraca sama lengan
Explanation
The correct answer is "neraca sama lengan". This is because a "neraca sama lengan" is a type of balance scale that has two arms of equal length. It is commonly used to measure the weight of objects, including rice in a sack. The equal arms ensure that the weight on one side is balanced by an equal weight on the other side, allowing for an accurate measurement.

### Suatu pengukuran menghasilkan nilai 0,02302. Angka penting yang terdapat pada nilai tersebut adalah......

• A.

Lima

• B.

Empat

• C.

Tiga

• D.

Dua

• E.

Satu

B. Empat
Explanation
The given measurement value is 0.02302. The significant figures in this value are four, which are the digits that carry meaning and contribute to the precision of the measurement. The zeros before the first non-zero digit (2) are not significant. Therefore, the correct answer is "empat" (four).

### Sebuah segitiga memiliki tinggi 627 cm serta alas 512 cm. Jadi luasnya adalah......

• A.

16

• B.

16,1

• C.

16,0512

• D.

16,051

• E.

16,05

B. 16,1
Explanation
The question asks for the area of a triangle with a height of 627 cm and a base of 512 cm. To find the area of a triangle, you can use the formula: Area = 1/2 * base * height. Plugging in the values, we get: Area = 1/2 * 512 cm * 627 cm = 161,376 cm^2. Rounding this to one decimal place, we get 16.1. Therefore, the correct answer is 16.1.

• B.

0,0807 mm

• C.

8,7 mm

• D.

0,087 mm

• E.

0,87 mm

E. 0,87 mm
Explanation
The correct answer is 0,87 mm. This is the most accurate measurement because it matches the given unit of measurement (millimeters) and has the correct number of significant figures. The other options either have too many or too few significant figures, or they are not in the correct unit of measurement.

• D.

Tekanan

• E.

Momentum

D. Tekanan
Explanation
The correct answer is "tekanan" because tekanan, which translates to pressure in English, is a dimension that measures the force applied per unit area. It is a fundamental concept in physics and engineering, and is used to describe the distribution of force over a given surface.

### Notasi ilmiah 125 000 000 000 adalah......

• A.

• B.

12,5 x

• C.

1,25 x

• D.

0,125 x

• E.

125 x

B. 12,5 x
Explanation
The correct answer is 12,5 x. The given scientific notation 125 000 000 000 can be written as 1.25 x 10^11. By moving the decimal point 11 places to the right, we get the number 125,000,000,000. Therefore, the correct answer is 12.5 multiplied by 10^11, which is represented as 12.5 x.

### Sesuatu yang digunakan sebagai pembanding dalam pengukuran adalah......

• A.

Satuan

• B.

Besaran

• C.

Turunan

• D.

Satuan turunan

• E.

Ukuran

A. Satuan
Explanation
The correct answer is "satuan" because in measurement, a unit is used as a reference or comparison to quantify a physical quantity. It provides a standard for measuring and expressing the magnitude of a particular quantity. Without a unit, measurements would be meaningless and incomparable.

### Alat untuk mengukur luas halaman yang paling tepat adalah......

• A.

Mikrometer sekrup

• B.

Jangka sorong

• C.

Mistar

• D.

Jangka

• E.

Segitiga

C. Mistar
Explanation
The most appropriate tool for measuring the area of a page is a "mistar" or a ruler. A ruler is a straight measuring tool with markings in centimeters or inches, which can be used to measure the length and width of the page. By multiplying the length and width measurements, we can calculate the area of the page accurately. Therefore, a ruler or mistar is the most suitable tool for measuring the area of a page.

### Alat pengukur waktu yang digunakan sebelum orang mengetahui tentang teknologi adalah......

• A.

Matahari

• B.

Jam pasir

• C.

Detik

• D.

Hari

• E.

Bulan

D. Hari
Explanation
Before the invention of modern technology, people used the natural phenomenon of the sun to measure time. They observed the movement of the sun across the sky and divided the day into different parts such as morning, afternoon, and evening. This division of time based on the sun's position allowed them to track the passage of days and determine the length of time between events or activities. Therefore, "hari" (day) is the correct answer as it represents the unit of time that was used before the discovery of technology-based timekeeping devices.

### Angka penting adalah semua angka yang diperoleh dari hasil......

• A.

Taksiran

• B.

Pembulatan

• C.

Perkiraan

• D.

Pengukuran

• E.

Perkalian

D. Pengukuran
Explanation
Angka penting refers to the significant figures or digits obtained from a measurement. It is a way to express the precision or accuracy of a measurement. In scientific calculations, only the digits that are considered significant are used, while any additional digits are rounded off or ignored. Therefore, pengukuran (measurement) is the correct answer as it directly relates to obtaining and using significant figures in calculations.

• D.

Empat

• E.

Lima

E. Lima
Explanation
The number 12,000 has five significant figures because all of the digits in the number are non-zero and are not trailing zeros. Therefore, the answer is "lima" (five).

C. 45
Explanation
The given question is asking for the angle between the x-component and y-component of a force vector. The correct answer is 45 degrees because when the x-component and y-component of a force vector have equal magnitudes, the angle between them is always 45 degrees.

### Hasil pengukuran sisi sebuah luasan didapatkan angka 175 m dan 130 m maka luas dari bidang tersebut adalah

• A.

2,2750

• B.

2

• C.

2,3

• D.

2,28

• E.

2,275

D. 2,28
Explanation
The given question provides the measurements of two sides of a shape, which are 175 m and 130 m. To find the area of the shape, we need to multiply these two measurements together. Multiplying 175 m by 130 m gives us a product of 22,750 m^2. However, the answer options provided are in decimal form. Rounding the area to two decimal places, we get 2.28. Therefore, the correct answer is 2.28.

• D.

Gaya

• E.

Momentum

E. Momentum
Explanation
The given question is asking to identify the scalar quantity among the given options. Scalar quantities are those that only have magnitude and no direction. Momentum is not a scalar quantity because it has both magnitude and direction. Therefore, momentum is the correct answer as it does not belong to the category of scalar quantities.

### Dua buah vektor masing-masing 5 N dan 8 N. Besarnya vektor resultan yang tidak benar adalah......

• A.

14 N

• B.

2 N

• C.

10 N

• D.

9 N

• E.

1 N

E. 1 N
Explanation
The correct answer is 1 N. The magnitude of the resultant vector is calculated by finding the sum of the magnitudes of the two given vectors. In this case, the sum of 5 N and 8 N is 13 N, not 1 N. Therefore, the answer of 1 N is incorrect.

• B.

6,78 x

• C.

6,78 x

• D.

6,78 x

• E.

6,78 x

E. 6,78 x
Explanation
The scientific notation of the given number 67,800,000,000 is 6.78 x 10^10. This is because scientific notation represents a number as a product of a decimal number between 1 and 10 and a power of 10. In this case, 6.78 is the decimal number and 10^10 represents the power of 10, indicating that the decimal number is multiplied by 10 raised to the power of 10.
