Describe the implementation the solution of the following problem
Problem- What number of photons per second of frequency 100 MHz is needed by an FM radio that can just detect a signal of 10-12 W?
I need experts help to find the solution of the above problem.
In the figure, a slab of mass m1 = 19kg rests on a frictionless floor, and a block of massm2 = 12 kg rests on top of theslab. Between block and slab, the coefficient of static friction is 0.30, and the coefficient of kinetic friction is 0.20.
