Question

6. Виразіть 2,3 км в м, см, мм 7. Площа парти 0,9 м 2 . Виразіть цю площу у квадратних сантиметрах. 8. У мірний циліндр налили воду, потім туди ж опустили скріпки. Як можна виміряти об’єм однієї скріпки?

Answer 1

Объяснение:

6). 2,3 км=2,3×100=2300 м

2,3 км=2,3×100000=230000 см

2,3 км=2,3×1000000=2300000 мм

7). 0,9 м^2=0,9×100^2=9000 см^2

8). V - объем воды

Vск - объем воды с n скрепками

объем одной скрепки вычислим по формуле:

$v_{1} = \frac{ v_{ck} - v }{n}$

Answer 2

Converting 2.3 km to m, cm, mm

To convert 2.3 kilometers to meters, centimeters, and millimeters, we can use the following conversion factors:

- 1 kilometer (km) = 1000 meters (m) - 1 meter (m) = 100 centimeters (cm) - 1 centimeter (cm) = 10 millimeters (mm)

Therefore, to convert 2.3 kilometers to meters, we multiply by 1000:

2.3 km = 2.3 * 1000 m = 2300 m [[1]].

To convert 2300 meters to centimeters, we multiply by 100:

2300 m = 2300 * 100 cm = 230000 cm [[2]].

To convert 230000 centimeters to millimeters, we multiply by 10:

230000 cm = 230000 * 10 mm = 2300000 mm [[3]].

So, 2.3 kilometers is equal to 2300 meters, 230000 centimeters, and 2300000 millimeters.

Converting the area of a square to square centimeters

To convert the area of a square from square meters to square centimeters, we can use the following conversion factor:

- 1 square meter (m²) = 10000 square centimeters (cm²)

Given that the area of a square is 0.9 m², we can convert it to square centimeters by multiplying by 10000:

0.9 m² = 0.9 * 10000 cm² = 9000 cm² [[4]].

Therefore, the area of the square is 9000 square centimeters.

Measuring the volume of a paperclip in a graduated cylinder filled with water

To measure the volume of a paperclip in a graduated cylinder filled with water, you can follow these steps:

1. Fill a graduated cylinder with water up to a certain level. 2. Carefully place the paperclip into the graduated cylinder, making sure it is fully submerged in the water. 3. Observe the change in water level in the graduated cylinder. 4. The difference in water level before and after adding the paperclip represents the volume of the paperclip.

To obtain an accurate measurement, it is important to ensure that the paperclip is fully submerged and that there are no air bubbles trapped around it. Additionally, you may need to account for the meniscus (the curved surface of the water) when reading the water level in the graduated cylinder.

Please note that the volume of a paperclip is likely to be very small, so it may be more practical to use a more precise measuring instrument, such as a micropipette or a digital scale, to measure its volume.

I hope this helps! Let me know if you have any further questions.
