I am pretty sure it is B My friend hope you are well
Explanation:
Answer:
let's say you're on a bus going 50 km/hr, you are moving at a velocity of zero relative to the bus. however, relative to the ground you are moving at the same velocity as the bus.

physics
Jello is just a gelatin dessert. Gelatin is extracted from bones and skin of certain animals, making it non-vegan actually. It comes in a variety of flavors like cherry and watermelon
Answer:
The value of the angle is ![\bf{ \sin^{-1}[h/am_{e}v]}](https://tex.z-dn.net/?f=%5Cbf%7B%20%5Csin%5E%7B-1%7D%5Bh%2Fam_%7Be%7Dv%5D%7D)
.
Explanation:
Given:
The condition for diffraction minima is
where, 
is the slit-width, 
is the angle of incidence, 
is the order number and 
is the wavelength of the light.
The wavelength of an electron traveling through a medium is governed by de Broglie's hypothesis.
According to de Broglie's hypothesis
Here, 
is Planck's constant, 
is the mass of the electron and 
is the velocity of the electron.
For first minimum 
.
From equation (1), we have
![&& a \sin \theta = \dfrac{h}{m_{e}v}\\&or,& \theta = \sin^{-1}[\dfrac{h}{am_{e}v}]](https://tex.z-dn.net/?f=%26%26%20a%20%5Csin%20%5Ctheta%20%3D%20%5Cdfrac%7Bh%7D%7Bm_%7Be%7Dv%7D%5C%5C%26or%2C%26%20%5Ctheta%20%3D%20%5Csin%5E%7B-1%7D%5B%5Cdfrac%7Bh%7D%7Bam_%7Be%7Dv%7D%5D)
