2. 1. Your best friend has missed a lot of school recently. Your teacher has allowed you to create a study guide and will let your friend use it on the test.
The guide should include:
• descriptions of amplitude, wavelength, frequency, and wave speed.
• Give examples of the wave relationship between amplitude and wavelength (if there is no relationship, explain how you know)
• Give examples of the wave relationship between wavelength and frequency (if there is no relationship, explain how you know)Text to speech
Answers
Answer:
Hi (best friend)! Here is what you missed!
Five wave parameters are defined and measured: the time, the frequency, the amplitude, the wavelength, and the speed. The wave length is the time it takes to pass a full phase. The frequency is just the opposite; it's the number of wave cycles that have been completed in a second.
Lets give a wave of water as an example. Its wavelength is the distance from crest to crest or from trough to trough. The wavelength can also be thought of as the distance a wave has traveled after one complete cycle—or one period. The time for one complete up-and-down motion is the simple water wave’s period T. In the figure, the wave itself moves to the right with a wave velocity vw. Its amplitude X is the distance between the resting position and the maximum displacement—either the crest or the trough—of the wave.
Define reactant.
Define product.
Define precipitate.

Answer:
Answers below!
Explanation:
Reactant- a substance that takes part in and undergoes change during a reaction.
Product- a substance produced during a natural, chemical, or manufacturing process.
Precipitate- 1. to separate from a solution as a precipitate. 2. to fall to the earth's surface as a condensed form of water; to rain, snow, hail, drizzle, etc.
Precipitate has different meanings so I didn't really know about which one, but tell me if I'm wrong :)
Answer:
Reactant: a substance that takes part in and undergoes change during a reaction.
Product: are the species formed from chemical reactions. During a chemical reaction reactants are transformed into products after passing through a high energy transition state.
Precipitate: a solid formed by a change in a solution, often due to a chemical reaction or change in temperature that decreases solubility of a solid

Answers
Answer:
Explanation:
A chemical property describes the ability of a substance to undergo a specific chemical change.
A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.
Differences
Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change.
Physical properties are properties that can be observed without bringing a chemical change.
Another one
chemical properties; can be used to predict how substances react.
chemical changes; It is mostly used in identifying or describing the substance.
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.

Energy and Temperature Activity Worksheet
Instructions: Follow the directions below to complete part one and part two of this activity. You will submit both parts once completed.
Note: You are not performing the experiment—only designing it.
Introduction
The purpose of this assignment is to design an experiment that another student could follow and use to test whether land or water heats faster.
You will complete the following:
Part One: Experimental Design. Plan out an experiment by answering the guiding questions below.
Part Two: Design a Lab Report. Write the outline of a lab report so that another student could complete the experiment by using the materials listed below:
sand
water
heat lamps
thermometers
cups
Part One: Experimental Design
In this section, you will think about what type of experiment to set up. Remember, you are NOT completing the experiment, only designing it. If you want to review the scientific method first, use this tutorial. Use these guiding questions to help you design the experiment. Answer each question below:
What hypothesis will the experiment test?
What are the variables?
What purpose would the sand serve?
What purpose would the water serve?
What purpose would the heat lamps serve?
What purpose would the thermometers use?
How can you use these materials to test whether land or water heats faster?
How would you compare whether land or water heats faster?
Within a 24-hour period, at what three points should the temperature be taken? Why?
What would an effective conclusion need to include?
Part Two: Design a Lab Report
Once you have designed the experiment, you must write out the instructions so another student could act as the experimenter and follow them. Fill in the following elements of this lab report as described in italics below.
Lab Report
Objective
Explain the purpose of your lab.
Procedure
List the experiment procedures. Some steps have been filled in for you. You may need to adjust the numbers to match the steps you decide on.
Identify the variables.
Write out your hypothesis in an if/then format.
Gather your materials.
Analyze the data.
Write your conclusion.
Data Analysis
Label a data table so that the experimenter can record observations for the sand and water temperatures at various points.
Conclusion
Explain what the experimenter should include in this section to show how the data proved the hypothesis.

How is energy involved in physical change?
Answers
During phase changes, energy changes are usually involved. For example, when solid dry ice vaporizes (physical change), carbon dioxide molecules absorb energy. When liquid water becomes ice, energy is released. Remember that all chemical reactions involve a change in the bonds of the reactants.

Answer:
75% straight
50% bent
Explanation:
because the Punnett Squares work that way
think of it as a multiplication table...when 2 numbers come to the middle, they give you the answer just like these squares (they're just smaller)
R + R = RR
R + r = Rr
R + r = Rr
r + r = rr
RR is 25%
Rr is 50% because there are 4 boxes and 2 of them is Rr
rr is 25%
Simpler answer:
I know because 25% + 50% = 75% for the straight root. 25% + 25% = 50% for the bent toot.

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally. How do Rosa’s body systems work together to get the molecules she needs into her cells? (Sentence starter: Rosa's body systems work together by...
Answers
Answer: ... being that the food she eats food that contains a lot of protein and also starch, so systems are both good for you and work together. Chemical energy is stored in the bonds of sugars. When a sugar molecule is broken down, a usable form of energy is released for the cell's life functions. Cells can release energy in two basic processes: cellular respiration and fermentation. ... In cells use oxygen to release energy stored in sugars such as glucose.
Explanation:
Answer:
What does she need from the food she ate and the air she breathes so that she can go on her run?
A. Rosa needs carbohydrates rich food (bread) to carry out her jogging activity. Protein-rich food before exercise is not recommended unless she is on a weight loss program (diet plan).
B. Rosa needs oxygen to perform aerobic respiration, which is required for maximum release of energy (36 molecules per reaction run). Anaerobic reactions yield less energy (2 molecules of ATP per reaction run) and are not recommended.
How do Rosa's body systems work together to get the molecules she needs into her cells?
Rosa's body cells need carbohydrates (glucose) and oxygen to perform aerobic respiration for the release of maximum energy. The glucose and oxygen molecules are provided to the cells via diffusion into the bloodstream. During exercise/jogging, complex molecules of carbohydrates such as starch (present in bread) are broken down into simple molecules (glucose) which are diffused into the blood. Likewise, a high amount of oxygen is provided to the body's cells via diffusion in blood, which is carried out by the faster movement of lungs and heart. The combined action results in the supply of both types of molecules to enter the cell where mitochondria use these substrates to produce energy molecules (ATPs).
