Answer:

The trade was difficult with the old system.

Explanation:

The existing system for the measurement of goods did not work well in the trade because there are different system used by the people of different cities so metric system was used in the whole country in place of the old system of measurement during the French Revolution in order to make the trade easier and quick across the country. This metric system is extensively used in the trade as compared to the old system of measurement due to its easiness and fast.

3. What is the volume of a salt crystal measuring 2.44 x 10-2 m by 1.4 x 10-3 m by 8.4 x 10-3 m?
AlexFokin [52]

Answer:

2.9× 10⁻⁷ m³

Explanation:

Given data:

Measurements of crystal = 2.44 × 10⁻² m by  1.4 × 10⁻³ m by 8.4  × 10⁻³ m

Volume = ?

Solution:

Volume is equal to the length by width by height.

<em>So from given measurement value:</em>

Volume =  2.44 × 10⁻² m by  1.4 × 10⁻³ m by 8.4  × 10⁻³ m

Volume = 2.9× 10⁻⁷ m³

So the volume from given values is 2.9× 10⁻⁷ m³.

Which of the following does not participate in, nor is a component of, the electron transport chain? (Remember that molecules ca
Yanka [14]

Answer:

A) coenzyme A

Explanation:

The NADH and FADH₂ are the energy rich molecules which are formed in the processes like glycolysis, TCA cycle and the fatty acid oxidation as they contain pair of electrons which have very high transfer potential.

As a result of the energy produced when these molecules transfer their electrons to the oxygen , ATP is generated by a series of electron carriers which collectively is called electron transport chain (ETC).

<u>The components of chain include Fe–S centers, Non-heme, FMN, coenzyme Q, and cytochromes . </u>

The energy derived from the transfer of electrons is used to pump the protons across mitochondrial membrane.

As a result, an electrochemical gradient is generated which results in some energy which is then harnessed by the ATP synthase to form ATP.

Compute 4.659×104−2.14×104. Round the answer appropriately.
pentagon [3]

Answer: 25,200.


Explanation:


1) Given: 4.659 × 10⁴ - 2.14 × 10⁴


2) You have to deal with significant figures.


Since, the powers are the same (10⁴) you can directly subtract the decimal numbers. But first analyze the significant figures and the number of decimal digits.


3) The number 4.659 × 10⁴ has four significant figures (4, 6, 5, and 9), while the number 2.14 × 10⁴ has three significan figures (2, 1, and 4).


4) When you add or subtract numbers with diferent amount of decimal digits, the result must show the same number of decimal digits as the term with the least number of decimal digits.


5) Before subtracting, you must round all the terms to the least number of decimal digits. So, since 2.14 has two decimal digits and 4.659 has three decimal digits, you shall round 4.659 to 4.66.


6) Now you subtract 4.66 - 2.14 = 2.52


7) Multiply by the power of 10: 2.52 × 10⁴ = 25,200. And that is the answer.
