Answer:
Part a)
Part b)
Since on the block wedge system there is no external force in horizontal direction so the Center of mass will not move in horizontal direction but in vertical direction it will move
so displacement in Y direction is given as
Explanation:
PART A)
As we know that there is no external force on the system of two masses in horizontal direction
So here the two masses will have its momentum conserved in horizontal direction
So we have
Also we know that here no friction force on the system so total energy will always remains conserved
So we have
now we have
so we have
and another block has speed
Part b)
Since on the block wedge system there is no external force in horizontal direction so the Center of mass will not move in horizontal direction but in vertical direction it will move
so displacement in Y direction is given as
What is the electromagnetic spectrum?
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10²⁵ hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus.
How the light affect the color we see?
All of the colors we see are a byproduct of spectrum light, as it is reflected off or absorbed into an object. An object that reflects back all of the rays of light will appear white; an object that absorbs all of the rays, black. All of the millions of other colors are produced by a combination of light rays being absorbed and reflected.
