Rose's mother prepares food in an oven, which consumes 200 KWh of electricity per day and the power company charges $10 per 100 KWh. Which of the tables shows the correct relationship between the electricity consumed and the amount charged? => Table 1 or Table 2..

Power - Imagine two students positioned at track A and track B of 100 m 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 or..

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 a Lens - 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 o..

Tidal Power - 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 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..
