Adhesion handles a meniscus, and this has to do in part with water’s fairly high surface tension. Water molecules are attracted to the molecules in the wall of the glass beaker.
The properties of water that contribute To The formation of the meniscus are:
cohesion and
adhesion
Meniscus is defined as the upward or downward curve at the surface of a liquid in a tube.
When water is placed in a tube or wettable container, a concave or downward meniscus is formed due to surface tension created in water through the following properties of water:
Cohesion: This is the tendency of water molecules to stick to itself.
Adhesion: This is the tendency of water molecules to stick to other molecules that are charged or polar.
Therefore, the cohesion and adhesion of water molecules contribute to the formation of meniscus.
Answer:
b) the standard deviation of the sampling distribution of the mean
Explanation:
Typically, the standard error of the mean is a term in statistics that describes the deviation in the sample mean from the actual mean of a population.
Therefore, in this case, the standard error of the mean is "the standard deviation of the sampling distribution of the mean."
Answer:
The difference between nonprobability and probability sampling is that nonprobability sampling does not involve random selection and probability sampling does.
Answer: The most obvious difference between part- and full-time students is the amount of credit hours they take during a semester. Part-time is usually somewhere between six and eleven credits or two to three classes. Therefore, a full-time student spends more time in class during a semester than a part-time student.
