Answer:
Independent variable: Different tyre treads
Dependent variable: Breaking distance
Constant: Same car
Explanation:
In an experiment, an independent variable is that variable which the experimenter controls or manipulates to effect an outcome. In this experiment, the tyre treads are changed to see if it would affect the breaking distance, hence, the DIFFERENT TYRE TREADS is the independent variable.
On the other hand, a dependent variable is the variable that responds to the manipulation of the independent variable. In other words, it is the outcome of the experiment. In this experiment, the BREAKING DISTANCE is the responding or dependent variable.
Constant or controlled variable is that variable that is kept constant or unchanged throughout the course of the experiment. The constant, if changed, will influence the result of the experiment. The constant in this experiment is the CAR since the same car (unchanged) was used for the experiment.

Explanation:</h3>
<u>Step 1: Define</u>
<em>Identify variables</em>
[Given] 6.7 L O₂
[Solve] g O₂
<u>Step 2: Identify Conversions</u>
[STP] 22.4 L = 1 mol
[PT] Molar Mass of O: 16.00 g/mol
[PT] Molar Mass of C: 12.01 g/mol
Molar Mass of CO₂: 12.01 + 2(16.00) = 44.01 g/mol

Answer:
Explanation:
Shifting, labor intensive and monoculture are different in terms of description,restrictions and problem.
Shifting is an agriculture method in which an area if land is cultivated for a while and abandoned for the soil to regain and preserve it's fertility. It is done to restore soul fertility.
It has restrictions because it is done in places where there is large areas of land, if there is not large area of land, it will be done.
It can lead to defforestation because trees are cut fine for land cultivation and after a while the land is abandoned and trees are cut down some where else too.
Labor intensive refers to agricultural industry requiring or needing large amount of labor to produce agricultural products. Labor intensive is restricted to areas where there is low or no people who can engage in agricultural services.
Labor intensive require high skilled people which might not be available.
Monoculture is a farming system where by a single crop is cultivated in an area of land.
The problem of monoculture is that it displaces species and nutrients occuring naturally in an ecosystem.
Monoculture is restricted in areas where diversity of crops are needed.
Because in difrent materials atoms are more compact or less compact.if they are less compact then it will be easear for them to move
