What are two variables held constant when testing boyles law in manometer?
Temperature & mass keep constant in Boyle's law. Volume and pressure are variable.
What is vibration testing?
"The procedure for vibration testing involves placing the product or package on a vibration testing table, which is driven so that the surface of the table vibrates. The most common types of vibration testing equipment are: Hydraulic Vibration
What is a controlled expirement?
an experiment that can be controlled i did not know this That is not a good answer! A controlled experiment is: If you set up an experiment: Example: You have two plants. You want to know if fertilizing every day causes it to grow more. In your experiment everything has to be the same! Except one thing. You have to have the same type of dirt and pot and flower/vegetable. You have to water each of them every day. But, you fertilize ONE of them once a day until your results are clear to you, or when you want to stop testing. This way, you can see how the fertilizer effects the plant growth compared to just water every day. If you change more than one thing, like how much you water the plant, it is not a controlled experiment anymore. because then you won't know which variable (thing that you have changed) is taking effect. You wouldn't know if it was more water or the fertilizer, or both that is making the plant grow faster!
What is the Meaning of latency in performance testing?
I just wanted to know What is the Meaning of latency in performance testing?
What atoll was used by the US for nuclear weapons testing?
The Bikini atoll was used for nuclear weapons testing.
Why do you need to keep variables the same?
In programming, variables change all the time. In scientific testing you control variables to determine what other changes occur.
Why is it it important to control variables in an expeiement?
It is important because without controling the variables, you will be testing more than one thing in the expirament at a time. you could get different answers. you only want 1 variable in science expiraments. you might also want a control, with the "normal one" to compare the expiraments with the variables to.

What are control and variables?
A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.
Is there another way to study the world other than by doing a controlled experiment?
Scientisists do mant different controlled expirements to see different results. To conduct a fair expirement, you must control all of the variables expect for the one you are testing.
Variables in an experiment whose effect you are testing?
'Known' Variables
What are the independent and dependent variables of how fertilizer affects plant growth?
The independent variable is the thing you are testing or the thing you control. The dependent variable is what you are measuring.
Something that causes changes in an experiment?
The factors that can influence the course of a reaction are known as variables and or sources of error. Experiments and testing seek to control these variables, errors and account for them to ensure quality and safety of their results.
What is fair testing in science?
Fair testing is when you test something with many variables, but you must change one variable. e.g. testing the different types ofdrinking water. [Tap water, hose water, etc.
How would you explain testing how two types of soap work using control and variable?
The control is what you're washing, amount of dirt, kind of dirt, temperature of water. The kind and amount of soap are variables, although when using the same kind in different amounts, the kind is control. The temperature of water is also control and variable depending on the test.
If you were testing well different dish soaps cleaned your dishes the control group would be?
If you were testing how well different dish soaps cleaned the dishes the control group would be dishes washed in plain water.
