Power Introduction
Power - A contractor wishes to lift a load of bricks from the sidewalk to the top of a building by means of a winch. Since we know the expression for work, we can calculate work to be done by the force applied by the winch to lift the load. We are interested in the rate at which it is don..

Whenever a ray of light passes through a lens (except when it passes through the optical centre) it bends. The bending of light rays towards the principal axis is called convergence and bending of light rays away from the principal axis is called divergence. The degree of convergence or divergence..

The family of all subsets of any set S is called the power set of S. We denote the power set of S by P (S). If a set S is finite, say S has n elements, then the power set of S can be shown to have 2 n elemen..

The tides are formed due to the gravitational force of attraction between the earth, sun and moon. During high tides sea water is trapped in a reservoir, and released later to drive turbines, which in turn produces electricity. The block diagram given below illustrates the transformation of energy..

Electric Power - The power is the rate of doing work or in other words, it is the work done in one second. If a current of 'I' amperes flow through a conductor of resistance 'R' ohm for a time 't' seconds when the potential difference across its ends is 'V' volt, then the electr..

Power of Accommodation
A normal eye can see both the distant and the nearby objects clearly. In the case of the eye, the image distance (v) is fixed as the distance between the eye lens and retina remains the same but the object distance (u) varie..
Resolving Power
The ability of the instrument to resolve the images of two point objects lying close to each other. Due to the wave nature of light each point object produces its own diffraction pattern, which overlap, and the image can no longer be identifie..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Tutor helped me on every question and help me when i was confused. Thank you Tutor Vista
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
