Definitions of the 3 types of variables in doing an experiment?
The three variable in an experiment are independent, dependent, and controlled. The independent is the variable you control, the dependent is the variable that will change according to the independent. The control is kept constant so they do not affect the dependent.
What is control group in science?
The one not experimented on. The control group is used to compare results to, to check that the changes you made during the experiment were responsible for the results seen in those groups. In other words, you use the control to confirm if the results shown in the experiment were caused by the independent variable (the variable that you change and are trying to investigate).
Why is it important to test only one variable at a time during a science investigation?
If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.
How can you control an expierment?
you have to have what is called a control group. This group consists of the test subjects that are notreceiving the test variable. For example: If i was trying to prove that 30 mins of exercise a day made for happier people, my control group would be the people that are not doing the 30 mins of exercise.
The four main parts of an experiment?
First and foremost you must specify the hypothesis you are testing by the experiment. So you will have a testable null and alternate hypothesis. Next you will detail the resources and procedures used to generate the data needed by the tests specified by the hypothesis. Then using the described resources and procedures you will generate and record the data specified by the first two components. Next you will perform the analytic tests on those data, and record those results relative to the specifications made by your hypotheses. Following that you will write a summary of your results test and conclude whether your null hypothesis was shown to be not false based on you experimental results. Finally, you will write recommendations for further action and/or experiments based on your own experiment.
What is the advantages of variable resistor?
When we want to regulate somthing ;we use variable resistors for example :volume control in radios and volume in headset. Also , the variable resistors can forms a potential devider in which the overall resistance between the two end points remain the same,but the ratio of the two resistors in the legs changes.so the variable resistor is affectively a potential divider. Also, the variable resistor can forms a potential divider in which the overall resistance between the two end points remains the same, but the ratio of the two resistors in the legs changes. So, the variable resistor is effectively a potential divider.

How can you get windows 7 to manage wireless connections?
A person can get Windows 7 to manage wireless connections by enabling the wireless network manager under the control panel. Windows will then remember all connections made and automatically connect to them when in range.
Why is it important to test only one variable at a time during a experiment?
If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.

In other words, you use the control to confirm if the results shown in the experiment were caused by the independent variable (the variable that you change and are trying to investigate).
Is a control and controlled variable the same in Science?
i'd think so, i think it's just the gramma correctness that made them different
How the connections are made in RFID and how it's operates?
ok i need the physical connections made in RFID.
Why is it important to test only one variable at a time during a science investigation?
If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.
Does the independent variable affect the dependent variable?
yes, because dependent variable is made by independent variable
When to use a rheostat?
Depending on the situation. The purpose of the rheostat is use to change the resistance of the circuit. The rheostat is use to define Ohm Laws the 2nd situation is use to find out what the fixed resistor's resistance. 3rd purpose : used to control the resistance of circuit. eg Radio
Variable's in science?
costants what controlls it as in what causes your projeect to failed what variable cause it to do good.what variable made a mess what variable cause it to work
Why do brothers make you made?
If your brothers are "made", they are likely to have the connections to get you "made" also.
