Answer:
The number of bright fringes per unit width on the screen is,
Explanation:
If d is the separation between slits, D is the distance between the slit and the screen and is the wavelength of the light. Let x is the number of bright fringes per unit width on the screen is given by :
is the wavelength
n is the order
If n = 1,
So, the the number of bright fringes per unit width on the screen is . Hence, the correct option is (B).
Answer:
A stretched rubber band has potential energy
Abiogenesis is the name of life on Earth.
To develop this problem it is necessary to use the continuity equations and Bernoullie's theorem.
It is known from Bernoullie's theorem that
Where
P = Pressure
g = Gravity
h= Height
v = Velocity
= Density
On the other hand we have that the continuity equation is given by
Where A is the Cross-sectional area and v the velocity.
For our values we know that
Using Bernoulli's expression we can now find the pressure difference,
