Explanation:
Questions
Section I: Experimental Overview
1. What is the purpose of the lab, the importance of the topic, and the question you are trying to answer?
The Purpose of the lab is to displace water to determine volume.And weigh objects to get mass. Then We would divide the two and get density.How do we determine density?
2. What is your hypothesis (or hypotheses) for this experiment?
You get mass from weighing objects and you get volume from displacing water. Then you can divide them both to get density.
3. What methods are you using to test this (or each) hypothesis?
We were using scales and water displacement methods to get density.
Section II: Data and Observations
4. Locate the data and observations collected in your lab guide. What are the key results? How would you best summarize the data to relate your findings?
In a lab guide, the key results are those that support my working hypotheses or serve to reject these assumptions. Moreover, the key results may also be other discoveries that are important to understand the processes and/or mechanisms investigated in the experiment.
In my experience, the best way to summarize the key results is to create diagrams and illustrations that enables me to study relationships between different data
5. Do you have quantitative data (numerical results or calculations)? Do you have qualitative data (written observations and descriptions)? How can you organize this date for your report?
yes from the experiments we received numerical data for each object then we would use that data to find the mass volume to get density. We drew pictures to create a visual representation. You can simplify it into a small short worded sentence.
Section III: Analysis and Discussion
6. What do the key results indicate?
That we got the density from the mass and volume. By using different methods to get them.
7. If you constructed graphs, what trends do they indicate in your data?
We didnt need to construct graphs.
8. Were there any problems with the experiment or the methods? Did you have any surprising results?
No there was not any weird things that happened. The findings were normal.
Section IV: Conclusions
9. What do the results tell you about your hypothesis(es)?
That we were right.
10. How do the data support your claim above?
That we were right about our hyphothesis.
11. If you could repeat the experiment and make it better, what would you do differently and why? there is no point
Writing the Lab Report
Now you will use your answers from the questions above to write your lab report. Follow the directions below.
Section I: Experimental Overview
Use your answers from questions 1–3 as the basis for the first section of your lab report. This section provides your reader with background information about why you conducted this experiment and how it was completed. Outline the steps of the procedure in full sentences. It also provides potential answers (your hypothesis/es) relative to what you expected the experiment to demonstrate. This section should be 1–3 paragraphs in length.
Section II: Data and Observations
Use your answers from questions 4–5 as the basis for the second section of your lab report. This section provides your reader with the data from the experiment, in a summarized and concise way. No paragraphs are required for this section, but you do need to include the key data and observations from which you will generate your analysis and discussion. This section is objective.
Section III: Analysis and Discussion
Use your answers from questions 6–8 as the basis for the third section of your lab report. This section provides your reader with your interpretation of the data set. You will also give an example of any calculations or formulas you used to analyze your data. Also, you will want to include any graphs that you made and interpret them for the reader.
If you did construct graphs, your Student Guide included information on which graphs to construct. Graphs should have the following:
a. Appropriate titles
b. Appropriate labels for each axis
c. Appropriate scales for each axis
d. Correct units for the data

What happens if two plates move away from each other?
Answer:
They will sometimes crash into other plates in the process and will rub while they are moving creating earthquakes
Explanation:
Which of the answer choices is a true statement? Select all that apply. Nonmetals usually exist as molecules, combining with atoms of themselves. Nonmetals can exist on their own as individual atoms. Metallic elements usually exist as molecules, combining with atoms of themselves. Metallic elements can exist on their own as individual atoms.
Nonmetals usually exist as molecules, combining with atoms of themselves and Metallic elements can exist on their own as individual atoms. therefore the correct options are options A and option D
What is a molecule?The smallest component of a material that still has its content and characteristics is called a molecule. It is constructed of two or more atoms connected by chemical bonds. Moles are the foundation of chemistry. Molecules are designated by their elemental symbol and a subscript denoting their atom count.
Atoms are the fundamental unit of an element. They consist of a nucleus and surrounding electrons. When an atom has an incomplete electron shell, it is said to have valence electrons.
Thus,Metallic elements can exist alone as individual atoms, while nonmetals typically exist as molecules that combine with other atoms of the same type. Therefore, options A and D are the best choices.

The kinetic energies of particles in a sample of matter are increasing. This sample is most likely
Answer:
The sample is most likely gaining thermal energy
Explanation:
If the kinetic energies of particles in a sample of matter are increasing, the sample is a liquid that is warming.
All particles have energy, and the energy varies depending on the temperature of the sample of matter. Solid particles have the least amount of energy, and gas particles have the greatest amount of energy.
The temperature of a substance is a measure of the average kinetic energy of the particles.
If the kinetic energies of particles in a sample of matter are increasing, the sample is a liquid that is warming.

What net force acting on a 14 KG wagon produces an acceleration of 1.5 MS^2?
Answer:
The wagon exerts a force of 21 Newtons
Explanation:
Force is equal to mass times acceleration, a Newton being 1 kg×m/². As we're given both the mass and the acceleration, all we need to do is multiply them to find the force applied:
14 kg × 1.5m/s²
= 14 × 1.5 kg × m/s²
= 21 N

Why do you sometimes get shocked by static electricity? Explain how it happens and give an example.
Answer:
That tiny shock you feel is a result of the quick movement of these electrons. You can think of a shock as a river of millions of electrons flying through the air. ... Static electricity happens more often during the colder seasons because the air is drier, and it's easier to build up electrons on the skin's surface.

Circle the scenario that shows balanced forces and will result in no movement of the gold bar.
Answer :1st one is the scenario that shows balanced forces and will result in no movement of the gold bar. (circled in attachment)Explanation :In the first scenario there are equal forces of 5N acting on both sides of the gold bar, but this is not the case for the second and third scenarios. Equal forces are acting on both sides of the bar in the first scenario, hence showing balanced forces and resulting in no movement of the gold bar.

How does gravity affect an object?
Answer:
it is a downward force
Explanation:
e.g: keeping humans on earth
Answer:
by gravitational force
Explanation:
The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it.
