Question

Ррзадание Выразите в джоулях работу: 0,25 кДж= 2,2 кДж= 0,15 МДж=1,2 МДж=670 Н·м=Заранье спасибо​

Answer 1

0,25 кДж=250 Дж

2,2 кДж= 2200 Дж

0,15 МДж=150000 Дж

1,2 МДж=1200000 Дж

670 Н·м=670 Дж

Answer 2

Calculating Work in Joules

To express the given values in joules, we can use the following conversions: - 1 kJ (kilojoule) = 1000 J (joules) - 1 MJ (megajoule) = 1000000 J (joules)

Given values: - 0.25 kJ - 2.2 kJ - 0.15 MJ - 1.2 MJ - 670 N·m

Calculations

1. 0.25 kJ to J: - 0.25 kJ = 0.25 * 1000 J = 250 J

2. 2.2 kJ to J: - 2.2 kJ = 2.2 * 1000 J = 2200 J

3. 0.15 MJ to J: - 0.15 MJ = 0.15 * 1000000 J = 150000 J

4. 1.2 MJ to J: - 1.2 MJ = 1.2 * 1000000 J = 1200000 J

5. 670 N·m: - The unit N·m represents newton meters, which is equivalent to joules (J). Therefore, 670 N·m is equal to 670 J.

Results

- 0.25 kJ = 250 J - 2.2 kJ = 2200 J - 0.15 MJ = 150000 J - 1.2 MJ = 1200000 J - 670 N·m = 670 J

So, the work expressed in joules is as follows: - 0.25 kJ = 250 J - 2.2 kJ = 2200 J - 0.15 MJ = 150000 J - 1.2 MJ = 1200000 J - 670 N·m = 670 J

I hope this helps! If you have any further questions, feel free to ask.
