Answer:
Explanation:
From the question we are told that
Initial velocity of 60 m/s
Wind speed
Generally Resolving vector mathematically
Generally the equation Pythagoras theorem is given mathematically by
Therefore Resultant velocity (m/s)
b)Resultant direction
Generally the equation for solving Resultant direction
Therefore
Answer:
4.63 p.m.
Explanation:
The problem given here can be solved by the Compton effect which is expressed as
here, is the initial photon wavelength,
is the scattered photon wavelength, h is he Planck's constant,
is the free electron mass, c is the velocity of light,
is the angle of scattering.
Given that, the scattering angle is,
Putting the respective values, we get
Therfore,
Here, the photon's incident wavelength is
So,
From the conservation of momentum,
here, is the initial photon momentum,
is the final photon momentum and
is the scattered electron momentum.
Expanding the vector sum, we get
Now expressing the momentum in terms of De-Broglie wavelength
and putting it in the above equation we get,
Therfore,
This is the de Broglie wavelength of the electron after scattering.
Answer:
The correct option is H
Explanation:
From the question we are told that
The index of refraction of coating is
The index of refraction of material is
Generally the condition for constructive for a thin film interference is mathematically represented
Here t represents the thickness
For minimum thickness m = 0
So
=>
