Upon the heating of black body the maximum of its spectrum shiftedfrom 690 nm to 500 nm. By what factor did the radiant emittance increase?
Consider a class Computer having Two fields (i.e. companyName, price) and A single
function named show()
A class named Desktop inherits Computer class and adds fields representing color,
monitor size, and processor type and Override function named show() to display values
of its all attributes
A class named Laptop inherits Computer class and adds fields representing color, size,
weight, and processor type and Override function named show() to display values of its
all attributes
In Main() instantiate objects of derived classes to access respective show() functions to
see the polymorphic behavior.
