Answer:
The phase difference is 
Explanation:
From the question we are told that
The distance between the slits is
The distance to the screen is 
The wavelength is 
The distance of the wave from the central maximum is 
Generally the path difference of this waves is mathematically represented as

Here
is the angle between the the line connecting the mid-point of the slits with the screen and the line connecting the mid-point of the slits to the central maximum
This implies that

=> 
![\theta = tan ^{-1} [\frac{5*10^{-3}}{1}]](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20tan%20%5E%7B-1%7D%20%5B%5Cfrac%7B5%2A10%5E%7B-3%7D%7D%7B1%7D%5D)

Substituting values into the formula for path difference
The phase difference is mathematically represented as

Substituting values

Converting to degree
the solution is subtracted by 360° in order to get the actual angle
I think this is the answer hope it helps
Nothing happens. The frequency is determined at the source,
and it doesn't change along the way.
Answer:
2 J
Explanation:
A charged capacitor of capacitance
with energy of 7.54 J, is connected in parallel with another capacitor
, so the charge is equally distributed between them.
(a) The energy stored in the capacitor before it being connected to the other capacitor is:

The energy stored in the electric field is the sum of the energies of the two capacitors:

since the charge equally distributed,
=
=
. and since they are connected in parallel the potential difference on both of them is the same
:

hence,
