A variable that doesn't change in an experiment is called a constant. Constants are used to ensure that only one variable is being tested for its effect on the outcome of the experiment.
direct current
Frequency is the parameter of light which doesnt change on reflection because it is the ratio of velocity of light in medium and wavelength of the particle.Hence,when velocity increases wavelength also increases and when velocity decreases wavelength also decreases but its ratio always remains constant.
A material that does not allow electricity to pass through it is called an insulator. Insulators have high electrical resistance, preventing the flow of electrical current. Examples of insulators include rubber, plastic, and glass.
nothing happpens. changing the shape doesnt do anything and adding more doesnt do anything either. the density will change tho if you add another chemical or substanceansthe above comment is correct. Unless you applied a force that changed its overall volume of course, whilst changing its shape.
The Foucault Pendulum experiment proves that the Earth rotates beneath the pendulum, which proved that the Earth rotates. If one were to make a pendulum on the equator it would not work because it doesnt rotate at that point of the Earth.
Independent Variable
The control, or constant.
The factor that doesnt change in your experiment
The factor that doesnt change in your experiment
When you dont have a control in an experiment , there is no basis of comparrison. A proper experiment , has an independent variable - purposefully changed - a dependent variable - measured result - a constant (that ones kind of obvious), and a control . When an experiment doesnt have a control , its also harder to draw conclusion. With a control , you have something to base your hypothesis on . If this doesnt help , try checking your textbook or search experimental design on google or ask.com.
EXPERIMENTAL SET UP * involves the set up that will allow you to investigate what you are interested to know. CONTROL SET UP * involves a set up that is exactly the same as the experimental, except the factor that you hypothesis to influence the results.
The control is the group that doesnt get tested
because if an experiment doesnt has information you could not stablish a topic and it wouldnot have sense
a variable changes a rule doesnt.
It doesnt actually change color, its called special effects.
it doesnt change
tectonic plates. just because they are convergent doesnt change the fact that they are tectonic..
