IPA Fisika 7

The correct answer is kilogram. The kilogram is the unit of mass in the International System of Units (SI). It is defined as the mass of the International Prototype of the Kilogram, a platinum-iridium cylinder kept at the International Bureau of Weights and Measures in France. The kilogram is widely used as a standard unit of mass in scientific and everyday measurements.

The correct answer is "sekon" because the question asks for the unit of time according to the SI (International System of Units). In the SI system, the standard unit of time is the second, which is represented by the term "sekon" in Indonesian.

The correct answer is 616 cm2. The formula to calculate the area of a circle is A = πr2, where A is the area and r is the radius of the circle. In this case, the radius is given as 14 cm. Plugging this value into the formula, we get A = π(14)2 = 616 cm2.

The correct answer is panjang, massa, waktu. These are the fundamental quantities in physics, known as the base quantities or fundamental dimensions. Panjang refers to length, massa refers to mass, and waktu refers to time. These three quantities are considered to be the building blocks for all other physical quantities and measurements.

The correct answer is 16 m2 because to find the area of a rectangle, you multiply the length by the width. In this case, the length is 5 m and the width is 3.2 m, so 5 m x 3.2 m = 16 m2.

The correct answer is 31.536.000. There are 365 days in a year, and each day has 24 hours. Therefore, to find the number of seconds in a year, we multiply 365 by 24 and then multiply the result by 60 (to convert hours to minutes) and then multiply again by 60 (to convert minutes to seconds). This calculation gives us 31.536.000 seconds in a year.

The conversion between cubic decimeters (dm3) and cubic meters (m3) is that 1 m3 is equal to 1000 dm3. Therefore, to convert 60 dm3 to m3, we divide 60 by 1000, which gives us 0.06 m3.

The conversion factor between milliliters (mL) and cubic millimeters (mm3) is 1 mL = 1000 mm3. Therefore, to convert 2.5 mL to mm3, we multiply 2.5 mL by the conversion factor: 2.5 mL x 1000 mm3/mL = 2500 mm3.

The correct answer is "besaran dengan besaran lain." This is because the word "mengukur" means to measure, and when measuring, we compare one quantity or magnitude with another. Therefore, the correct answer states that measuring involves comparing one magnitude with another.

The given options are different units of volume measurement. The correct answer is 10,000 L because it is the largest volume measurement among the options provided.

The speed of sound in room temperature is 5 m/s. To convert this speed to kilometers per hour, we need to multiply it by a conversion factor. There are 1000 meters in a kilometer and 3600 seconds in an hour. Therefore, the conversion factor is (1000/3600) km/s. By multiplying 5 m/s by this conversion factor, we get 1.3889 km/h. Rounding this to the nearest whole number gives us the answer of 18 km/h.

Satu sentimeter kubik (1 cm3) adalah sama dengan satu mililiter. Ini karena satu sentimeter kubik adalah satuan volume yang setara dengan volume yang diisi oleh sebuah kubus dengan panjang sisi satu sentimeter. Satu mililiter adalah satuan volume yang setara dengan satu cm3, sehingga keduanya memiliki nilai yang sama.

The correct answer is 40.000 cm2 because 1 meter is equal to 100 centimeters. Therefore, 4 meters squared is equal to 4 multiplied by 100 multiplied by 100, which equals 40,000 square centimeters.

An ideal measurement standard should be easily replicable by others, meaning that it can be easily copied or imitated. However, it should not change over time, indicating that it remains consistent and stable. This combination ensures that the measurement standard can be consistently applied and compared across different contexts and time periods.

The correct answer is 0,005 sekon because 1 milisekon is equal to 0,001 sekon. Therefore, 5 milisekon is equal to 0,005 sekon.
