Answers

Answer 1

Answer:

All matter is in continual random motion.

Explanation:

Because Kinetic Molecular theory is based on a principle idea that tiny particles such as gas particles are always in motion.

Answer:

1. [tex]10.6\; \rm m[/tex] (one decimal place.)

2.[tex]0.79\; \rm g[/tex] (two decimal places.)

3. [tex]16.5\;\rm cm^2[/tex] (three significant figures.)

Explanation:

The first and second expressions are additions and subtractions. When adding two numbers, the accuracy of the result is given by the number of decimal places in it. The result should have as many decimal places as the input with the least number of decimal places.

For example, in the first expression:

[tex]5.6792\;\rm m[/tex] has four decimal places.[tex]0.6\; \rm m[/tex] has only one decimal place.[tex]4.33\; \rm m[/tex] has two decimal places.

Therefore, the result should be rounded to one decimal place. Note that these units are compatible for addition, since they are all the same. The result should have the same unit (that is: [tex]\rm m[/tex].)

Therefore:

[tex]\rm 5.6792\; m + 0.6\; m + 4.33\; m \approx 10.6\; \rm m[/tex]. (Rounded to one decimal place.)

Similarly:

[tex]\rm 3.70\; \rm g[/tex] has two decimal places.[tex]2.9133\; \rm g[/tex] has four decimal places.

Therefore, the result should be rounded to two decimal places. Its unit should be [tex]\rm g[/tex] (same as the unit of the two inputs.)

[tex]\rm 3.70\; g - 2.9133\; g \approx 0.79\; \rm g[/tex]. (Rounded to two decimal places.)

When multiplying two numbers, the accuracy of the result should be based on the number of significant figures in it. The result should have as many significant figures as the input with the least number of significant figures. In this expression:

[tex]4.51\; \rm cm[/tex] has three significant figures.[tex]3.6666\; \rm cm[/tex] has five significant figures.

Therefore, the result should have only three significant figures.

The unit of the result is supposed to be the product of the units of the input. In this expression, that unit will be [tex]\rm cm \cdot cm[/tex], which is occasionally written as [tex]\rm cm^2[/tex].

[tex]\rm 4.51 \; cm \times 3.6666 \; cm \approx 16.5\; \rm cm^2[/tex]. (Rounded to three significant figures.)

A Daring and Dastardly Deed: Act 1, Scene 2: Hannah and her mother are at the supermarket. They are waiting in line for a cashier. Hannah's mother has a shopping cart full of groceries. HANNAH: (Very excited): The thing about Sherlock Holmes, Mom, is that he sees things that other people don't. He uses his powers of observation and deduction to solve crimes. He has an incredible knowledge of crimes and villains and the many dastardly deeds they engage in to break the law. He uses his wit and courage, too. HANNAH'S MOTHER: (Partly distracted, answering while choosing a checkout line to stand in) Dastardly deeds? That's an interesting phrase. I'm glad you enjoyed the story. In fact, you seem happy as a dog with two tails at the moment. HANNAH: (Feeling thoughtful and confident) Well, maybe that's because I've decided that I'm going to be an investigator. From The Mystery of the Shiny Paper: Hannah started to think about Holmes' many skills and character traits. The skills he relied on most of all were observation and deduction. Sherlock Holmes paid a lot of attention to detail and would often notice things that other people missed. Hannah decided that this was where she would start on her road to becoming a detectiveobserving others and attempting to deduce information from her observations. She spent the rest of the walk back to her house observing others and trying to come up with detective-like deductions. A few days later, she was at the supermarket with her mother, still trying to hone her investigative skills by observing others, when she thought to herself: This is hopeless. I don't have any chance of solving a mystery! She felt a bit down on the way home and her mom asked her twice if she was feeling okay. "I'm okay, Mom," was all she said.
