Aufbau Principle
The Aufbau principle states that in the ground state of an atom, an electron enters the orbital of lowest energy first, and then the subsequent electrons are fed in the order of increasing energies into the orbitals. The relative energies of various orbitals are given in fig.1.6. From the..

The Principle of Windmill
When the blowing wind strikes across the blades of a windmill, it exerts a force on them due to which the blades of the windmill start rotating. This in turn rotates the shaft of the turbine and generates electricity. ..

Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
Thank you very much for helping to me is very important to have my lessons. Because you manage to take good notes in school thank you Tutor Vista
