Electric dipole

If two equal and opposite charges placed at some distance apart. This two charge system is called an electric dipole.

Here, '2a' is the dipole length.

Note :-

Total charge in an electric dipole = -q + q = 0

Electric dipole moment 'p'

It is the product of the magnitude of one charge of the dipole and the dipole length.

It is a vector quantity directed from negative charge to positive charge. Its SI unit is Cm(coulomb metre).

Wind Energy | wind generators | advantages and disadvantages of Wind Energy by - advguruji

Moving air is called wind. Wind has energy. The energy possessed by wind is due to its high speed. So we can say the wind possesses kinetic energy . It is the kinetic energy of wind which is utilized for doing work. Solar energy or sun's energy is responsible for the blowing of wind, due to the uneven heating of earth by the sun in different regions. Now let's discuss about what is a wind mill. Wind mill The energy of wind is harnessed by using a windmill. A windmill consists of big sized table fan like blades which are fixed over the top of a tall pole in such a way that they are free to rotate when the fast moving wind strikes on the blades of the windmill. It makes the blades rotate continuously. The rotatory motion of the windmill is then used to do Mechanical work through a shaft connected to the rotating blades. The traditional use of wind energy has now been modified by the improvement in technology to generate electricity through wind powered generators. Wind Generator ...

Age problems (for practice) | class 10 mathematics | advguruji | Physics Advocate

Linear Equations Q1. Ten years ago, father was twelve times as old as his son and ten years hence, he will be twice as old as his son will be. Find their present ages. Ans. Present age of father = 34 years Present age of son = 12 years Q2. Three years ago, Priya's mother was six times older than her. Four years from now, Priya's mother will be one year older than thrice her age. Find the present age of Priya and her mother. Ans. Present age of Priya = 8 years Present age of mother = 33 years Q3. Five years ago, Rakesh was five times younger than his mother. Ten years from now, his age will be half of his mother's age. Find the present age of Rakesh and his mother. Ans. Present age of Rakesh = 10 years Present age of mother = 30 years Q4. (equation in one variable) A is elder to B by two years. A's father F is twice as old as A . ...

What if we can contact Aliens ? by Physics Advocate/advguruji

Before the beginning, first discuss about aliens. Aliens are those creatures which do not belong to our world. Now a question comes to your mind. Can we contact aliens? The answer is most probably NO. But why? Because first we have to find that type of planets (or natural satellites) which can support life. This is not an easy task. Also, a planet which can support life is not enough. Why? Because life can exist in various forms. One form is unicellular organisms. For example, in our solar system it is believed that Titan (Saturn's moon) can support unicellular life. But the disadvantage is we cannot contact them by our communication methods. But yes, there is a high possibility in future that a rover mission can take some samples of the unicellular or may be small multicellular organisms and send the data to Earth. Now comes the interesting part. If a planet is supporting complex life like animals, plants or even species like us (humans), then also there are very very...
