It is due to absorption of energy in each reflection by the plane mirror and alos due to attenuation offered by the space on the electromagnetic waves as it gets reflected many times on both the mirrors.
A foam padding made from acoustic foam or neoprene material would be a good sound reverberation reducer for a clear glass or plastic tank. These materials dampen sound vibrations and help to reduce noise transmission. They are also often available in clear or translucent colors to maintain visibility within the tank.
What must a scientist do to determine whether the data supports the hypothesis?
The scientist has to organize the data in some meaningful ways, and these ways are probably going to be determined by the experimental design chosen. The scientist can do some calculations to quickly look at general trends, and then employ statistical analysis to get a more exact estimate of the strengths of the outcomes.
How does temperature differ from a thermal change?
Temperature refers to the average kinetic energy of particles in a substance, while thermal change refers to the transfer of heat energy between two substances at different temperatures. Temperature is a measure of the intensity of heat, while thermal change describes the process of heat transfer.
Why is it important to document every step of an experiment?
Documenting every step of an experiment is crucial for several reasons. It ensures reproducibility, allowing others to replicate the study and verify results. Additionally, thorough documentation helps identify sources of error and improves understanding of the experimental process. Finally, it contributes to the body of scientific knowledge, enabling future researchers to build on previous work.
Is it true that a well conducted experiment will show the hypothesis to be true?
Not all hypotheses can be proven, no matter how well controlled.
What are the steps to follow in an experiment?
Use the scientific method.
1. First find the question you're looking for.
2. Do background research.
3. Make a hypothesis.
4. Test it by doing an experiment.
5. Analyze your data/ draw a conclusion.
6. Communicate/ Spread your results.
Oh and I'm in the middle of researching for an experiment in 7th Grade :P
Why is a control group important to a controlled experiment?
Because without it, it wouldn't be organized.
What does form a conclusion mean?
In going into an investigation of some kind, including a scientific experiment, one has a hypothesis, an idea of what is going on. On this basis one devises a test which will go one way if the hypothesis is correct but another way if it is not.
If the test or experiment definitely confirms the hypothesis or definitely disproves it, it is possible to form a conclusion--to reject or accept the hypothesis.
This procedure is used in fields other than science:
- In history, the historian may form a hypothesis about an event in the past, test it with the available historical data and form a conclusion.
- In crime investigation, a detective may form a hypothesis about who the perpetrator is and test it against the evidence (or perform further tests to find more evidence) and form a conclusion whether the crime was in fact committed in that way.
- In cooking, a cook may devise a new way of preparing food, will test it out and form a conclusion whether it was a good idea or not.
Why is it important to read instructions all the way through before beginning the experiment?
If you do not read all the instructions before doing a experiment, something bad could happen. If you are dealling with chemicals in a science experiment, something could explode, turn into a terrible gas. Also, instructions will tell you is you should or should not breath in right near a substance, or touch one.
What are factors that can change an experiment in which only one variable is manipulated at a time?
um varible i think now
Why is it important in an ideal simple experiment to change only one variable from trial to trial?
If you change more than one independent variable and your dependent variable changes, you wont know which independent variable caused the change to occur.
eg - If I change something will I run 100m faster.
So your dependent variable is the time it takes to run 100m
If you have 2 independent variables (shoes and surface run on), you might run first in tennis shoes on grass then in football boots on tarmac.
Now say you ran faster the second time, you wont know if you ran faster because you were wearing boots, or if you ran faster because it was on tarmac or because of some boots-tarmac combination.
That's why you only change one independent variable.
Aim: Does changing X effect Y (only change X; only measure Y)
What does adequate mean in a science experiment?
Adequate means good enough. It means the same thing in a science experiment as it does in any other context.
Why are there water droplets form on the window of an air-conditioner bus?
The interior of the bus is cooler than outside the bus because of the air conditioner. Water vapour outside in the air touches the cooler surface of the window of the bus and condenses to form water droplets on the window.
When ou begin an experiment why should you create a table to a record your data?
Easy way to record, acceptable way to show findings, looks more professional than simple notes, shows rises/falls and if you are in school often by looking at the table you van work out why you did the experiment in the first place
What is 362 031 100km2 scientific notation?
3.620311 * 10^8 km² or
3.620311 * 10^14 m² when strictly using SI units.
How do you answer a hypothesis in an experiment?
it is a educated guess
ANS2:You can answer the hypothesis by either proving it false or by failing to prove it false. One must never claim to have proven an hypothesis true.Truth does not exist in science. You can find truth in logic, mathematics, and religion.
What is the full form of lmw turbine?
Its related to turbine design liningrad machine works by russian design
What does low specific gravity means in materials?
It means that the material has a low density. The practical implication is
that a lot of it doesn't weigh much.
How does wishing on a shooting star work?
it is just a belief because you can very rarely see a shooting star and also your wish will very rarely come true.
What are the types of a variable?
the types of variables are three the constant,manipulated and responding...
