Eratosthenes determined the circumference of Earth by conducting an experiment. Put his steps in order as they correlate to the scientific method

The provided question is incomplete, However, the missing part of the question is as follows:

1. State the Problem:

2. Make a Hypothesis:

3. Make Observations:

A) If the sun casts shadows at different angles at the same time of day in different places, we can determine how much Earth curves.

B) In Syene, the sun's rays are vertical at noon. At the same time in Alexandria, the rays are 7.2 degrees from the vertical.

C) How can we prove Earth is round and calculate its circumference?

The correct order would be : C, A, and B.

Explanation:

Scientific method for a experiment involves various steps in order such as finding a problem, make a hypothesis, creating observations, conducting experiment, collecting data, analyzing the data, making conclusion and repeating the process.

Option c is a problem about the circumference if earth about how can prove the round and calculate circumference. Option A is hypothesis related to this problem and option C. is observation.

Thus, the correct answer is C, A, B.

4)WRITE FULL FORM OF IUPAC.

Explanation:

1.Dry ice is the solid form of carbon dioxide. It is used primarily as a cooling agent, but is also used in fog machines at theatres for dramatic effects. Its advantages include lower temperature than that of water ice and not leaving any residue.

2.The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century.

3.Ammonia gas

Ammonia gas is used as a developer in diazotype method to make blue prints.

4.The International Union of Pure and Applied Chemistry (IUPAC /ˈaɪjuːpæk, ˈjuː-/) is an international federation of National Adhering Organizations that represents chemists in individual countries.

5. All metals have some amount of resistivity to electrical currents, which is why they require a power source to push the current through. The lower the level of resistivity, the more electrical conductivity a metal has. Copper has low resistivity, and therefore is an excellent conductor.

6.gold and silver are used to make ornaments because in they are the least reactive and do not react with any thing . Gold and silver are ductile (cam be made into thin wires ) and they have a metallic lustre.

7. I am too smalll I am frecking 10 yrs

8. A value-added tax, known in some countries as a goods and services tax, is a type of tax that is assessed incrementally. It is levied on the price of a product or service at each stage of production, distribution, or sale to the end consumer.
