What the term Variable means?
In math, a variable means something in an equation whose numerical value is not defined. In science, it refers to the things in an experiment that are manipulated by the experimenter. In computer science, a variable is a name that points to a storage location.
What is current value after derating factor considered?
Once derating factor is considered the size of cable for perticular electrical load increased by the multipling factor.i,e if 2.5MM2 cable is capable to carry 14amp. of current in general then with 40% of derating fator it can carry only 8.4amp.
What is a set down transformer?
A stp-down transformer steps voltage down from a high value to a low value. Transformers only work with AC.
What is the difference between sign and unsign in Java?
Normally, signed and unsigned data types just refer to whether or not a value can be negative or not. An unsigned 4-bit value can be the values 0 to 15 A signed 4-bit value can be the values -8 to 7 However, there is no such thing as an unsigned value in Java*. All primitive types are signed by default and cannot change. *Note that technically a char value can be considered an unsigned type. The only way to see this is to declare a char with value '\uffff' (or 65535) and try to print it out as both a short and an int. If you try this with any other data types, the larger values will display the same as the smaller values. Not so with the char example.
The value of gate voltage for the operation of enhancement of only N channel MOSFET has to be?
high...
What was the shortest experiment in scientific history?
In 1963, physicist Jack H. Hetherington performed an experiment that lasted only 30 minutes to prove a theoretical point. This experiment is considered one of the shortest in scientific history.
What is scientific worth mean?
Scientific value is only a type of thinking from a INTJ's mind. Basically it says that this scientific value matters the most above anything present on universe.it defines everything with scientific explanation.
How many experiments are necessary to invalidate a scientific hypothesis?
Only one, providing it is repeatable.One! Replication of the experiment result confirms the result in the scientific community.
When is the only time an experiment is considered a failure?
An experiment is never a failure. Experiments are just to find out what happens.
How should data be collected and displayed in the scientific method?
The scientific method does not detail how you do an experiment, only the method used in general terms.
Is an experiment considered a controlled experiment if it contains tests with chemicals?
No, it could be one, but that does not necessarily classify it as controlled. A controlled experiment is an experiment that has only ONE independent variable, and other variables are kept the same.
Why must the parameters of a scientific experiment be controlled?
If the parameters are not controlled in a scientific experiment, then one cannot be sure what the variables are. Unless you conduct the experiment in a closed environment with only only one variable, one's results can be confusing and inconclusive.
How can you improve your data accuracy in a lab experiment?
According to the scientific method, any scientific experiment must be done at least 3 times. Also, only one variable can be changed in an experiment (the independent variable). Any more changes will will ruin your dependent variable (your results) and make your data unreliable. If your experiment fails, learn from it, redo the experiment, and change another variable.
What does fermium commonly react with?
Fermium is considered a transuranium element that is highly unstable. It has some scientific uses but has not real commercial value.
What do scientists do when the evidence from experiments does not support a scientific theory?
They do the experiment again, double check all their calculations, then they come up with a new theory if it's necessary. That's why there's no such thing as a scientific fact, only scientific theories.
Can scientific inquiry be constructed about any scientific question?
No. There are questions whose possible answers can't be tested by experiment, and are therefore not answerable by scientific means. The classic one, though not the only one by far, is the question of the existence of God.
How many variables should change in a scientific experiment?
It depends what kind of experiment you do. For some you just need one. For others you may change two variables. In most cases you only change one
