18m. It does not matter what direction the cat walked as long as it walked in a certain direction for said amount of distance
Independent variable: calculators, computers
Dependent variable: speed
3 constants: seat, atmospheric condition, and time.
Control: none
<h3>What are variables</h3>
Variables are of different types in experiments. They can be:
- Independent: a variable that is supplied by the researcher and which can be tweaked among different experimental groups to produce different outcomes.
- Dependent: variables whose value is dependent on the kind of independent variable supplied by the researcher. It is the actual variable that is measured during the course of experiments.
- Constant: all other variables that are kept the same among experimental groups.
Thus, in this case, the independent variable will be the calculator or computer/calculator combination given to the two groups.
The dependent variable will be the speed at which each group finished solving the math problems.
The constant variable will be all other variables supplied to the two groups.

New molecules would form.
the other three are examples of a physical change
Answer:
D. Thermal conduction is blocked by the flip-flops.
Explanation:
Convection is a process of heat transfer which involves fluids( liquid or gas). This however rules convection out of the answer.
Radiation involves heat transfer from the sun to bodies on earth.
Conduction involves heat transfer between two solid bodies. Hot beach sand and flip-flops are solid bodies which validates thermal(heat) conduction.
