в некоторых двух точках электрического поля точечного заряда потенциалы электрического поля отличаются в n=2 раза . Во сколько раз отличаются напряженности электрического поля в этих точках ?

Ответ:

4 раза

Объяснение

ф=k*q/r Напряженность обратно пропорциональна квадрату расстояния: E=k*q/r^2 Значит напряженности отличаются в 2^2=4 раза

4. Early Birds like Tea; Night Owls like Alcohol
The lark is more likely to consume more tea than the night owl. But what about coffee? Here’s the interesting part. According to another study with 537 participants, night owls are more likely to consume caffeine from coffee and cola and they are also more likely to consume alcohol and nicotine. The latter is apparently related to the fact that owls are more likely to indulge in night life where intoxication is prevalent.
5. Early Birds are Creative during Night Hours; Night Owls are Creative in Morning Hours
No, there is no typing error here! Reportedly, night owls and morning birds have their bursts of creativity during their “off hours”. In a study conducted by Mareike Wieth and Rose Zacks in 2011, participants that included both night owls and early birds were given analytical and insight problems to solve. While analytical problems were successfully solved during optimal timings, insightful problems that required creative thinking were better solved during non-optimal hours – meaning during their less preferred hours. What do you know? Apparently those bursts of creativity are common occurrences during periods of mental fatigue.
6. Early Birds are Older; Night Owls are Younger
This obviously doesn’t meant that the clocks of time are cheated and being a night owl makes you younger—although we wish it were that simple. This simply means that your optimal hours might depend on your age. Older people are more likely to be early birds while younger people tend to enjoy late night bed times. Scientists found that this could be due to circadian clocks of skin cells and circadian genes. According to researcher Steven A. Brown, of the Institute for Pharmacology and Toxicology, “he can tell whether you are a ‘lark’ or an ‘owl’ simply by looking at your skin cells”. Not surprisingly, elder people tend to have earlier peak expression in the body cells causing them to go to bed early and wake up early.
7. Early Birds Love Breakfast; Night Owls Love Dinner
Our most preferred hours not only affect moods, choice of stimulants, and how we tend to work, but also our favorite meal choice. While early birds tend to wake up in the morning and eat a healthy breakfast while reading the newspaper simultaneously or doing something else productive, night owls tend to skip breakfast all together and use their last few minutes before work to get dressed and rush to the office. For night owls, dinner and day-time meals are the best and they make sure they are full of it.
Dr Simon Archer, a researcher from the University of Surrey did a test on himself and found that he had the “physiology of an owl” so he can’t eat breakfast first thing in the morning. Another study revealed that owls are more likely to eat fewer but larger meals during late hours. Thus, these individuals were more prone to obesity, elevated stress levels, and even sleep apnea.
