Answer:
Therefore the correct statement is B.
Explanation:
In the interference and diffraction phenomena, the natural wave of electromagnetic radiation must be taken into account, the wave front that advances towards the slit can be considered as when it reaches it behaves like a series of wave emitters, each slightly out of phase from the previous one, following the Huygens principle that states that each point is compiled as a source of secondary waves.
The sum of all these waves results in the diffraction curve of the slit that has the shape
I = Io sin² θ /θ²
Where the angle is a function of the wavelength and the width of the slit.
From the above, the interference phenomenon can be treated as the sum of two diffraction phenomena displaced a distance equal to the separation of the slits (d)
Therefore the correct statement is B
The process that water redeposit into a lake in the form of rain is precipitation.
<h3>What is water runoffs?</h3>
Water runoff occurs when there is more water than land can absorb.
The water flows across the surface of the land and into nearby creeks, streams, or lakes.
Runoff can come from both natural processes and human activity.
When rain falls to the earth from clouds and runs downhill into rivers and lakes.
During evaporation, the water turns from liquid into gas, and moves from oceans and lakes into the atmosphere where it forms clouds.
<h3>What is precipitation?</h3>
Precipitation is any liquid (rain) or frozen water that forms in the atmosphere and falls back to the Earth, for example it could fall on land or into lakes and rivers.
Thus, the process that water redeposit into a lake in the form of rain is precipitation.

Answer:
Explanation:
The density changes means that the length in the direction of the motion is changed.
Therefore,
Given :
Side, b = h = 0.13 m
Mass, m = 3.3 kg
Density = 8100 
So,
l = 0.024 m
Then for relativistic length contraction,
Therefore, the speed of the observer relative to the cube is 0.9833 c (in the units of c).
Answer:
Explanation:
As we know that system of two boxes are moving on frictionless surface
So here if two boxes are considered as a system
then we have
Now since we know that both the boxes are moving together so force applied by first box on other box is given as
Answer:
The value is 
Explanation:
From the question we are told that
The amount of power delivered is 
The time taken is 
The wavelength is 
Generally the energy delivered is mathematically represented as
Where 
is the Planck's constant with value 
c is the speed of light with value 
So
=>
