Electric flux is the number of electric field lines penetrating a surface or passing through a surface.

The electric field can be uniform or non-uniform. Let us now try to find the electric flux passing through a surface when the field is uniform.

Planet Biography. Planets Surface Temperatures. Why temperatures differs from planets to planets? In general, the surface temperature decreases as the distance from the sun increases. Venus is an exception because its dense atmosphere acts as a greenhouse and heats the surface above the lead's melting point of 880 ° F (471 ° C).

The Difference Between Being Intelligent And Being Wise

Intelligent : •   wise, cunning, capable of thinking and reason Wisdom: • The state of being wise • Ability to use knowledge and / or experience wisely • Able to determine what is wise against what is unwise • A saying, a philosophy or other advice considered wise In Short:  An intelligent man has a whole sea of knowledge and knows every fact. On the other hand, a wise man does not have all the knowledge that an intelligent man has, but he has the brain to know when to use knowledge. I have seen a lot of smart people make really stupid decisions. I was one of those people! The information I had before and after these decisions has not changed. But with every wrong decision, if I was willing to learn, my level of wisdom changed. The main difference is that: A smart or intelligent person knows how to solve any problem. A wise person knows how to avoid this problem. Knowledge makes a person intelligent. Experience makes a person wise.

Why Do People Fail In Life?

Because short term gratification is more appealing than not having a social life for X years. Hence, people end up tricking themselves by picking easy majors and easy goals. What kind of a sadomasochist wants to prioritize when you can just Netflix & chill? If a person hears “no,” he quits. Apply a little pressure or infuse the situation with a struggle and not a clear straight path and the person loses his shit. Not being realistic enough. Most likely, a Ph.D in mathematics at the age of 45 when you can’t grasp arithmetics is not pragmatic. Not having clear goals. I am not a fan of to do lists, but calendar planning works. Also, try to write down a “what I did today” list at the end of the day. If you didn’t do anything, that guilt feeling will kick in. Comparing yourself too much with others. You start to feel envy, to feel inadequate, and to feel ridiculed by your own self because you start to lose rationale. Not having gratitude, not having the ability to be happy wi...
