Answer:
independent variable -- different batteries
dependent variable -- the time that clock stop
Explanation:
In an experiment or a research study, there are two type of variables that can affect the result of the experiment or the conclusion. They are independent variable and the dependent variable.
An independent variable may be defined as that variable in an experiment which can be changed or can be controlled in the scientific experiment in order to test the effect on the dependent variable. It cannot be changed by other variables.
On the other hand, dependent variable are those are those which can be altered or change that can affect the experiment.
In the context, Emily uses the different types of the batteries as an independent variable and the time where the clock stopped in the dependent variable in her research.
Answer:
Electrons In The Shells
Explanation:
This element is one of the transition elements that doesn't place the additional electrons in the outer shell, but in the one underneath. For the fourth period/row, all of these electrons build the third shell to a maximum of 18 electrons.
The density is given by the formula , where d is density, m is the mass and v the volume. The 7ml of water displaced is the volume of the solid so
