Answer:
Rachel is going to succeed in her finals. She will do great. On the contrary, Leah is likely to fail her exams.
Explanation:
Pessimism is defined as a tendency to believe or think that something wrong will happen. Pessimistic people are quite negative and they always think that bad things outweigh good things. If Leah always expects the worst, the worst will happen. In contrast, Rachel always expects the best, as a result, the best will happen or it is more likely to happen. If you desire good things, good events will happen. If not, the opposite will occur. This is how the law of attraction works: you attract things that vibrate on the same frequency. Therefore, if you maintain a high frequency (like Rachel, expecting the best from life), you will find good things (love, compassion, positivity). If you are constantly vibrating low (negative emotions, feelings, like Leah), there will be inevitably bad outcomes.
Answer: Ivan Pavlov
Due to his experiments, he influenced other scientists. The experiment that he is most known is: Pavlov's dogs.

dogs and was looking at salivation in response to the food. At a certain
point, whenever he entered the
room, the dog would start to salivate even when he was not bringing them
food. This it is an unconditioned response to an unconditioned
stimulus.
C.) A sound wave cannot travel in a vacuum because there are no molecules to transfer energy.
