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 difference between toughness from impact test and toughness from tensile test?
A tensile test is performed by stretching the material until it breaks. An impact test is performed by applying a sudden shock to the material so that it fractures.
A grade 8 science experiment involving kinetic molecular theory?
Hmm, experiment's concerning Kinetic Molecular Theory. Simple experiment's off the top of my head are a ballon, with a hot and cold water bath, observe the effects of temperature on volume. Another temperature vs. volume experiment (more like demonstration, if this is for the 8th grade) is: placing approximately 5mL of water in a empty soda can, heat on a hot plate until steam starts to form, using tongs place the can upside down in a pan of cold water, the gas inside the can cools and contracts thus decreasing the internal persure and making a satisfying implosion, you can experiment with heating times to get the coolest implosion (if the can stops steaming take off the hot plate, there is no more water!). Those are the two that I can think up right now. I'll ask my AP chem teacher to help.
How does a thermometer indicate the temperature of an object?
The heat of the object heats the metal tip and heats the liquid inside (usually mercury) until it expands, thereby filling the thermometer. Various tests are performed to determine at what length is what temperature.
What is meant by the statement physics is an experimental science?
An experimental physicist also has hypotheses and theories, but they devise actual experiments to show these hypotheses are true (or not).General Relativity is one example where it is shown true by both mathematics and by experiments. The latest experiment to show General Relativity is true is the satellite "Gravity Probe B", which orbited the earth (still is) for a couple of years gathering data on what's called "frame dragging" -- which is a prediction from General Relativity math that had not been shown by experiment (until now).
What is a non manipulated variable?
A manipulative or manipulated variable in an experiment is the variable that can be varied to give different results during the course of an experiment. For example to determine how much sugar will saturate a liter of water, we keep increasing the amount of sugar until the water becomes saturated. Here sugar is the manipulated variable. Very easy! At first, I was confused with it too!
Why can a variable be used to represent a number?
Because somethings, like profit are dependent on other factors so, profit is unknown until such factors are accounted for.
What does varbile mean in math term?
If you mean a variable then it is an unknown quantity that can represent many values until its specific value is determined usually by solving an equation.
What is a independent variable?
in a experiment, the factor that is deliberately manipulatedAn independent variable is the variable that changes and the dependant variables are the variables that don't change. So that would mean that the independent variable is typically the variable being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated.An independent variable is a variable in an experiment that is changed to test a hypothesis. The dependent variable relies on the change of the independent variable to change itself.
What are the 3 variables in a science fair project and what do they mean?
The three variables of a science project are: 1. Controlled variable: A controlled variable means the part of the experiment that stays the same. This is also called the dependent variable. 2. Manipulated variable: A manipulated variable is something that can be changed by the experimenter. Also known as the independent variable. 3. Responding variable: A responding variable is the variable which you have to measure to get your results. So, you do not know the values of this variable until you measure it.
When using a scientific method what is always assumed correct until proven wrong?
in the scientific method the hypothesis is always assumed correct until proven wrong by the experiment that is being performed
What affect does salt to freezing point hypothesis indipendent and dependent variable?
An "hypothesis" doesn't have independent and dependent variables until you design an experiment to test it. If you want to test the effect that salt in solution has on the freezing point of the solution, then the independent variable is the presence, absence, or concentration of the salt. The dependent variable is the freezing temperature you measure in each condition.
What changes in an experiment?
It depends what you mean by that. But in an experiment that is made up of several tests, one factor at a time must be changed in order to rule out each possible factor until only one remains. Also test conditions may change if performed on a different day. Hope that helps you!!
What is an experiment in which neither the participant nor the individuals running the experiment know if participants are in the experiment or the control group until after the results are tallied?
A double-blind study.
To use inverse operations on both sides of an equation until the variable appears by itself on one side?
Isolate the variable
What is the probability of selecting a constant from the letters?
Until the letter is selected, it is a variable. Immediately after it is selected, the outcome is no longer a variable but a constant.
Does Andrew Lincoln of The Walking Dead smoke?
The answer is unknown, and will likely remain unknown until it is released to the public.
