The difference between logical data independence and physical data independence:
The ability to alter the conceptual schema without having an impact on the external schema is known as logical data independence.
The capacity to alter the internal schema without having an impact on the conceptual schema is known as physical data independence.
Achieving logical data independence is more difficult.
The specifics of the physical data are irrelevant in the physical data independence and have no bearing on the applications that represent the external schema.
However, in the case of logical data independence, the connection between the application and the external schema makes it difficult to design constraints that will not impact the applications when the conceptual schemas are changed.

The quantity of transmission is increased and the amount of reflection is reduced when the refractive index of medium one is greater than that of medium two.
More about refractive index here:
The refractive index determines how much light is bent or refracted when it strikes a substance. This is explained by the Willebrord Snell's Law of Refraction.

The movement from __________ to __________ is consistent with a decrease in the price of cotton (a substitute).
The movement from Point A to Point H is consistent with a decrease in the price of cotton (a substitute).
There's no doubt that the movement from Point A to Point H is consistent with a decrease in the price of cotton. After all, cotton is a substitute for wool, so when the price of cotton goes down, the demand for wool increases. This, in turn, drives up the price of wool.
But there's more to the story than that. The decrease in the price of cotton may also be due to a decrease in demand for other textile products, such as linen and silk. When the demand for these products decreases, the demand for cotton decreases as well. This, in turn, drives down the price of cotton.
So, while the movement from Point A to Point H is consistent with a decrease in the price of cotton, there may be other factors at play that are causing the price of cotton to decrease.

Increasing the sample size has what type of impact on a specific confidence interval?
An increase in the sample produces a narrower confidence interval with a smaller margin of standard error.
A specific confidence interval provides a range of values that reflects the true population parameter. It can be said that a specific confidence interval depends to a great extent on the sample size. The change in confidence interval occurs with the change in the sample size. It is because the standard error varies with the sample size. As the sample size increases, the confidence interval decreases yielding the minimum standard error rate.
Increasing the sample size produces more information and the estimation of the result tends to be more precise because of a decrease in uncertainty. When uncertainty decreases in turn, it reduces the width of the confidence interval with a minimum margin of standard error. Eventually, it becomes more sure that the result is more accurate and reflects the whole population.

When you are trying to remove solid impurities from a hot solution, the worst process to use would be:_________
When you are trying to remove solid impurities from a hot solution, the worst process to use would be removing the solvent with a Pasteur pipette.
Solid impurities from a hot solution are generally removed through suction filtration by crystallization. What is done is the solid impurities are first poured with a hot solvent. The soluble solid particles get dissolved in the hot solvent while insoluble solid particles are filtered, this is called hot filtration. The desired solid compound is then crystallized while cooling the solution and then the crystallized impurities are collected through suction filtration.
The worst procedure to remove the impurities is with a Pasteur pipette. Filter Pasteur pipettes are filled from the top with the impure solution having solid impurities in it. The solid impurities are left behind while the liquid is filtered through the pipette.
It is time-consuming, needs lots of concentration, and uses a large apparatus to clean up the impure substances. It is thus the worst method to remove solvent impurities.
