multiplying decimals by 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..

Every fraction with denominator 10 can be written in decimal notation. 1/10 can be written as 0.1 in decimal notation.The dot represents the decimal point and it come between the units place and the tenths place. One will read this as zero point o..

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..
