Answer:
Wavelength = 0.15 nm
Frequency = 
Explanation:
We have given photon energy E = 8 KeV = 8000 eV
In question it is given that 
So 
Plank's constant 
We know that photon energy is given by 
So 
Now wavelength 
Answer:
Particles can be classified as hadrons – baryons and mesons – and leptons, each with its anti-particle, and they should know that interactions between these particles can be described in terms of transfer of other particles known as vector bosons.

<h2>Answer: Sedimentary rocks
</h2>
Sedimentary rocks are formed from sediments and deposits of particles of various types, forms and sizes that are transported by air, wind or water, and then subjected to chemical processes to become rocks.
These types of rocks are usually found in the form of layers or strata in places where sediment accumulates due to the erosion of other materials, for example on the banks of rivers, in valleys, lakes (and any other type of body of water).
