Dimitri is studying the evaporation of water. He spent a week measuring six cups of water three times a day to see how much water evaporated. He is preparing to create a graph of the measurements he recorded. What step of the scientific method is Dimitri working on?a)creating a hypothesis
b)conducting an experiment
c)analyzing the data
d)drawing a conclusion

Answers

Answer 1

Answer:

Answer: C) Analyzing the data

Explanation: The hypothesis is an assumption or proposed explanation that has yet to be proven as an exact or starting point for further research. Since Dimitri does not proceed from the assumption, he has already carried out the experiment and recorded all changes in the evaporation of water, we can conclude that there is no hypothesis in question. As he has already carried out all the measurements and is preparing to create a chart of measurements he has recorded, we can conclude that the chart will analyze the recorded data, so the step of the scientific method in which Dimitri is working on, is analyzing the data. Only after completing this step of the scientific method he will make a conclusion.

Answer 2

Answer: he is working on analyzing the data

Which of these changes resulted from the United States' entry into World War II?The birthrate among young couples in urban areas decreased significantly.
Women entered the industrial workforce in large numbers for the first time.
African Americans were able to eliminate major forms of legal discrimination.
Labor unions gained thousands of new members and increased political power.

Answers

United States entry into World War II made women enter the industrial workforce in large numbers for the first time.

The skilled labor of women was symbolized in the United States by the concept of Rosie the Riveter, a hardworking woman who performed work that was once considered 'men's work'.

With this expanded horizon of opportunities and confidence, and with the extended knowledge base, many women could now have paid and voluntary employment, the roles of women in World War II were much broader than in World War I.

In 1945, more than 2.2 million women worked in the war industries, in the construction of ships, aircraft, vehicles and weapons. The women also worked in factories, ammunition plants and farms, and also drove trucks, provided logistical support for the soldiers and entered professional work areas that were previously the exclusive domain of men.

Women entered the industrial workforce in large numbers for the first time. (I think this is the Answer because in WW1 I'm not sure if women played a big role in industry)

When the nation's leaders met in 1787, these three problems needed to be addressed: tax collection irregularities in voting procedures law enforcement trade between the states slavery?

Answers

The correct answer is tax collection, law enforcement, and trade between states.

All of these problems were a result of the weaknesses in the Articles of Confederation. The Articles of Confederation was America's first constitution. Scared of having a strong central government, the Americans created a system in which state governments had almost all the power. All of the problems listed represent actions that the central (aka federal) government struggled with under the Articles of Confederation. In order to be a successful country, this needed to be changed.

Final answer:

The steam engine revolutionized manufacturing by providing a new power source for machines. It allowed factories to move away from rivers and bring about major advancements in the manufacturing and transport industries.

Explanation:

Of the given options, the steam engine provided manufacturers with a new source of power for machines. The steam engine was an invention of the Industrial Revolution that significantly propelled advancements in manufacturing and transport. It uses steam produced by boiling water to create motion, which is then transferred to machines for output. This allowed manufacturers to relocate their factories from riversides (the past main source of power) to places where raw materials and labor were cheaper and more abundant.
