You might be good at studies and have ability to learn fast , even the subjects that are considered tough like physics , mathematics, computer science e.t.c., or you might be the one struggling to learn these subjects. This article is for all those who are preparing for one exam or the another. Now once you complete understanding your topic you were studying , you move to another one and then to another one. After a week or two of continuously studying or learning new topics each day you now try to solve problems related to topic you studied two or three weeks back.
When a PN junction is reversed biased it allows very small current to flow through it. This current is due to the movement of minority charge carriers and it is almost independent of the voltage applied.
If reverse bias is made too high, the current through PN junction increases abruptly and the voltage at which this phenomenon occurs is called breakdown voltage .
For one dimensional motion, the force can be found from Potential energy using following formula
Question: When a person walks on the floor? which direction force is applied by the person to move forward?
Question: According to Newton’s third law,each team in a tug of war pulls with equal force on the another team
What then determine which team will wins it
Two most common errors you should avoid when you see an average speed question.
The most common mistakes in average speed problems occurs when the question asks you to calculate the average speed of a object moving at two different speeds for different parts of the journey. Students are generally tempted to calculate the arithmetic mean (average) of the two speeds, and select a corresponding answer. This averaging approach is wrong.

Phenomenon of superconductivity was first observed by Kamerlingh Onnes in Leiden in 1911 ,3 years after he first liquified helium gas. He observed that electrical resistivity of such as mercury, tin, lead completely disappear i.e., suddenly dropped to zero in a small range of temperature at a critical temperature TC which is the characterstics of the material.
1)Checkout all your things you required during exam time Pen , Pencil, sketch Pens, rubber , sharper ,each and everything whether it is small or big matters a lot during your exam time
