Answer:
All the statements are true
Explanation:
Viscosity is affected by temperature. For example, if we put heat over some liquids like honey and syrup, they tend to flow more freely. On the other hand, if the temperature gets cold the viscosity tends to thicken (ex: engine oil of a car during winter). These examples make the first statement true: “Viscosity increases as temperature decreases”. Viscosity is affected by pressure too. To see a change in a “molecular level”, the pressure needs to be very extreme. This make the second statement true: “Viscosity increases as molecular weight increases”. Taking in consideration both statements, we can conclude that the third statement is also correct. When viscosity is put into heat and little pressure, it tends to lessen, since the interaction between the molecules decreases and the intermolecular forces decreases. On the other hand, by default, when viscosity is put in a cold weather and pressure increases, the level of viscosity thickens, since the molecules start colliding and their motion becomes disorganized.

Answer:
construct validity of the effect
Explanation:
construct validity in research refers to how much the variables that is used in the research forms a correlation with the things that intended to be measured.
From the case above, we know that we want to research the effect of empathy.
But, people show their empathy in a very wide variety of ways. (for example some of them show it through tears, some of them through direct help, some of them through physical contact, etc). Because of this, we do not have any sure method that applicable to all subjects, which make it impossible to find a correlation between the subject's actions and the amount of emphatic. This will cause research end up lacking in construct validity of the effect.
Answer:
Explanation:
This is because they believed that they were superior to whatever culture was living there already, and also, normally what people thought of the Europeans was as if they were gods, so that added to the domination.
Answer:
gravity is an invisible and rather uncontrollable Force that pulls things to earth or to an object for example the Earth's gravity keeps things from floating to space
