well it really depends on which experiment you are carrying out, but usually no.

Do i have to start all over again if i forgot to zero a scale in an experiment?
Yes. All scales must be zeroed out. It's hard to tell how it affects the results.
Why is it hard for the results of one experiment to become a theory?
For something to become a theory it must be widely recognized as a legitimate way to answer the certain question. The trouble with the results of one experiment is that it may be true or perhaps the results depend on a hidden variable or more. If the results are replicated under slightly different conditions, we become more confident in the generalizing of the results. (Concept: It happened in this experiment vs. it will happen in all similar experiments.)
What is a magnet formed by electricity called?
Electromagnet. This is a type of magnet which the magnetic field is produced by the flow of electric current through wires generally surrounding a metal or iron core. Electric motors, generators, relays, loudspeakers, hard disks are examples of Electromagnets in other equipment.
How does electricity create magnetic power?
Electricity and magnetism are the two facets of the electromagnetism force. It means that where ever there is electricity flowing in a conductor there is also a magnetic field produced. The intensity of the electric current flowing in a wire determine the intensity of the magnetic field that arise near the wire. So here's one easy way to make an electromagnet. You take a big iron nail (the iron here act like a concentrator of the magnetic field). Then you make as many turn you can with some insulated copper wire around the nail (you can find very nice wire in the windings of an old transformer). You plug both ends of the wire to a D size battery after removing the insulation at the ends of the wire. When connected, try your new electromagnet on small iron nails.
How hard are bullets?
HARD
What is the independent variable in a line graph?
Independent variable is the one to be investigated; the one that will be changed to get results. If you are still finding it too hard just keep this in your mind-- Independent variables answer the question "What do I change?" in an experiment. Dependent variables answer the question "What do I observe?"!
What are mediating variables?
variables that think too hard....
Are variables hard data?
No; there is no such thing as "hard data".
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
What is memory variables?
Hard to tell, variables usually are in the memory... be more specific.
What is the definition of the variable?
Answer in definitions1. Something that varies in value.2. A temporary storage place used in computer applications during calculation.3. An algebraic term which is undefined but tied to the value of an expression.In programming, a variable represents a temporary storage location, used by the program to store something.For example, in:var x = read();print "you printed ", x"x" is a variable.In science, a variable is a factor that can be or is changed in an experiment. Often all variables except two are kept the same, while one (the independent variable) is changed for the experiment, and the other (the dependent variable) changes depending on the independent variable's value.In mathematics, a variable is as defined above; an term which can change in value, this value being necessary to the value of an overall expression it is in.control variables are those variables that are not changed throughout the trails in an experiment.
Difference between dependant and independant variable?
dependent: factors of a experiment that scientist observe, and can be changed by the outcome of the independent variable independent: a factor of a experiment that changes because you change it on purpose
Abut maxwell's thermsodynamic relation and its application?
Certain variables in thermodynamics are hard to measure experimentally such as entropy. Maxwell relations provide a way to exchange variables
Why is it hard to do an experiment with a red tablet?
it is hard because you'll never know that the acid in your stomach is colored in red xD
Why is graphing a system of inequalities a good way to show the solution set?
I am not at all convinced that it is. With more than three variables it is almost impossible and even with 3 variables, it is hard going.
