When the component simple harmonic motions have dissimilar periodic times:
The resultant curve may be attained in this case by dividing the circumferences of the two circles of reference into parts in the ratio of the periodic times, so that the projections of the parts on respective diameters give the displacements because of the individual simple harmonic motions in equal intervals of time.
- The slope of the tangent drawn on the U versus X graph provides us the value of the restoring force acting on the block.
- The graph can be used to attain the value of PE stored in the spring at any stage.
What do you mean by Doppler effect? Derive a mathematical expression for the apparent frequency of a note, when source of sound and observer are approaching each other.
A flat aluminum plate of 0.2 m thickness is initially at 120 Celsius. At time t=0, it is immersed in a liquid at 10 Celsius. Assume a very large heat transfer coefficient on both t
In an electric field rate of change of potential with distance is called as potential gradient. It is a vector quantity and its direction is differing to that of electric field. Po

HYSTERESIS LOOP: A ferromagnetic material retains some magnetism after the magnetising force is removed. The BH curve (O to Q) will therefore only be followed once, on initial
Frequency:- The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz.
