Springs

A mass m is attached to a spring of spring constant K1 If the spring is cut in to two halves and one of the pieces is attached to the same mass m compare the frequencies of oscillation
(Kendriya vidyalaya 2013)
υ1=1/2π×SQRT(K1/m)
Note that the spring constant ∞ (1/length of spring)
or K× l = a constant
υ2=1/2π × SQRT(2K1/m) ( as length is halved spring constant will be  doubled)
••• υ1/ υ2=1: √2

Graphs and Level curves of functions of Two variables Definitions The set of points (x,y) in the plane where a function f (x,y) has a constant value f(x,y)=c is called a level curve of f The set of all points (x,y,f (x,y)) in space, for (x,y) in the domain of f, is called the graph of f The graph of f is called the surface z=f (x,y) The equation of the following hyperbolic paraboloid is `z=50+x^2-y^2`

IBM Q computing using QIS kit had made quantum computing very simple we can embed the python code for quantum computing in IBM Q notebook without much mess. We can run the code in simulator and interestingly we can run the code even in  IBM quantum computing device!!!! Please click the link Quantum computing enthusiast  IBM Qcomputing beta version A code showing Bell state and its drawing
