how do you do powers of ten

Power - Imagine two students positioned at track A and track B of 100m length shifting 10 bricks from one end of the track to the other end. What is the amount of work done by each one of them? The amount of work done is same but the time taken to perform the work varies. In ord..

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 electric power consumed..

Whenever a ray of light passes through a lens (except when it passes through the optical center) 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..

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 done, that is, will t..

Magnifying power of an astronomical telescope may be defined as the ratio of the angle subtended at the eye by the image to the angle subtended at the eye by the object. From the ray diagram we know that: P l C is the focal length of the objective and P l D is the focal length of the eye ..

The magnifying power of a compound microscope is defined as the ratio of the size of the final image (I 2 ) as seen through the microscope to the size of the object as seen with a naked eye. Image Formation in a Compound Microscope = m o b j e c t i v e x m e y e p i e c e = m o x m e Whe..
