Answer:
I would say A, Gravity can help erosion to occur.
Explanation:
While B,C,D do help cause erosion, that isn't the only way erosion can occur.
According to <span>Le Chatelier's Principle," when a system at equilibrium is subjected to any external stress by changing concentration, pressure or temperature, it will modify itself in such a way so as to minimize the effect of that change made in it".
Change in Concentration:
Suppose following reaction at equilibrium,
A + B </span>⇆ C
When the concentration of reactants (A or B) is increased the equilibrium will shift in forward direction and will produce more product in order to cancel out the effect of extra reactant added. Or, if product (C) is added then it will respond in opposite direction.
Change in Pressure:
Suppose following reaction at equilibrium,
A + B ⇆ C
If pressure is applied on this equilibrium, the equilibrium will shift in forward direction because there is a decrease in volume at product side (1 mole as compare to reactants which are 2 moles). And the opposite case will be observed if the pressure is decreases.
Change in Temperature:
Suppose following reaction at equilibrium,
A + B ⇆ C + Heat
This is an exothermic reaction (heat is evolved) and the heat produced is in the product side. When the temperature is increased the equilibrium will shift in the backward direction. And decrease in temperature will shift the equilibrium in forward direction.
Answer:
In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. State what steps you will take to design an experiment to test your hypothesis. Complete the experiment. Make observations. Record what happened during your experiment.
Answer:
The answer to your question is length is an extensive property
Explanation:
There are two physical properties: extensive and intensive properties.
An extensive property is a property that depends on the amount of matter.
An intensive property is a property that does not depend on the amount of matter.
