Answer:
A laboratory report has three main functions:
(1) To provide a record of the experiments and raw data included in the report,
(2) To provide sufficient information to reproduce or extend the data, and
(3) To analyze the data, present conclusions and make recommendations based on the
experimental work.
General Comments:
The single most important requirement for a laboratory report is clarity. Imagine that your
audience is one of your classmates who missed that experiment.
If you are using a word processor for your lab report, then use the spelling and grammar
checkers. The grammar check can be annoying because often technical sentences are wordy
and complex, but it will help you avoid using too many passive sentences. In general, passive
sentences are less understandable. However, grammar check will not assess clarity, and it will
ignore simple errors. (I do not doubt there are still mistakes in this document I have run it through
spelling and grammar checks.)
Many technical writers prefer to write sentences with passive verbs. A simple example: “The
spring constant k was found from the slope to be 3.02 N/m.” If you run this sentence through the
grammar check, it will tell you that “was found” is a verb in the passive voice. To change this to
an active voice you could write: “The spring constant k is the slope, 3.02 N/m.” Not every
sentence has to be in an active voice. What you want is a report that is readable.
Lab Report Structure:
I. Cover Sheet: This page has the course number and assigned lab section, the title of the
experiment, your name, your lab partner’s names, the date that the lab was performed and
your TA’s name.
II. Abstract: The purpose of an abstract in a scientific paper is to help a reader decide if your
paper is of interest to him/her. (This section is the executive summary in a corporation or
government report; it is often the only section that a manager reads.)
The abstract should be able to stand by itself, and it should be brief. Generally, it consists of
three parts which answer these questions:
What did you do? – A statement of the purpose of the experiment, a concise
description of the experiment and physics principles investigated.
What were your results? – Highlight the most significant results of the experiment.
What do these results tell you? – Depending on the type of experiment, this is
conclusions and implications of the results or it may be lessons learned form the
experiment.
Write the abstract after all the other sections are completed. (You need to know everything in
the report before you can write a summary of it.)
III. Data Sheets: For each experiment, the lab manual has one or more data sheets for
recording raw data, as well as, intermediate and final data values. These are not for doodling,
but for recording your data. Record the data neatly in pen. If your data values are so sloppily
recorded that you have to recopy them, then the accuracy of the data is questionable. This
fact will be reflected in your laboratory performance score. If there is a mistake, then draw a
single line through that value. “White-Out” and similar covering agents are expressly
forbidden.

What might you predict about the use of wind power five years from now?
HELPPP PLSSss
Answer:
Due to global warming, more wind turbines would be built to help climate change. Wind power stations are expensive so even if there would be more wind turbines, there won't be a lot of them because people won't be able to afford electricity with such a high price.
In an ecosystem,due to global warming, more wind turbines would be built to help climate change.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Explain how Saturated Solution can dissolve no more solute
Answer:
saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. The additional solute will not dissolve in a saturated solution. The amount of solute that can be dissolved in a solvent to form a saturated solution depends on a variety of factors.
Explanation:
Answer:
When the solute equilibrium point is achieved and no more solute will dissolve, it is saturated.

How might it benefit forensic scientists to smaller subcategories for fingerprints?
Answer: Once the fingerprints are captured and described, judicial physicists use a categorization structure to label the ruling class. The three elementary mark on finger patterns is Whorl, Arch, and Loop. There are more intricate categorization methods that further decay the pattern to plain arches or make camp arches. Loops grant permission be branching or ulnar.

Explain at least one observation you can make about the political borders and the language borders shown on the maps.
Be sure to name the country and describe how its political border is affected by language or a physical feature, such as bodies of water, mountains, or desert.
Use the physical map with the labeled nations to help you identify a nation.
Answer:
A boundary is a real or imaginary line that separates two things. In geography, boundaries separate different regions of the Earth.The most obvious type of boundary is a physical boundary. A physical boundary is a naturally occurring barrier between two areas. Rivers, mountain ranges, oceans, and deserts can all serve as physical boundaries. Many times, political boundaries between countries or states form along physical boundaries. For example, the boundary between France and Spain follows the peaks of the Pyrenees Mountains, while the Alps separate France from Italy.
The Strait of Gibraltar is the boundary between southwestern Europe and northwestern Africa. This narrow waterway between the Atlantic Ocean and the Mediterranean Sea is an important political, economic, and social boundary between the continents.
Rivers are common boundaries between nations, states, and smaller political units such as counties. The Rio Grande forms a large part of the boundary between Mexico and the United States. The Mississippi Riveris the defining boundary between many of the states it winds through, including Iowa and Illinois, Arkansas and Tennessee, and Louisiana and Mississippi.

Answer:
1. Main sequence stars have different masses. The common characteristic they have is their source of energy. They burn fuel in their core through the process of fusing hydrogen atoms into helium.
2. Supergiants are among the most massive and most luminous stars. Supergiant stars occupy the top region of the Hertzsprung–Russell diagram with absolute visual magnitudes between about −3 and −8. The temperature range of supergiant stars spans from about 3,400 K to over 20,000 K.
3. Supergiants develop when massive main-sequence stars run out of hydrogen in their cores.
4. a supernova occur When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds. This collapse produces the explosion.
5. when a star has reached the end of its life and explodes in a brilliant burst of light
