Answer: The answer is B
Explanation: It is staying in a steady speed position
Answer:
Open circuit
Explanation:
An open circuit is simply an electrical circuit that is not complete. In such a circuit, there is a gap and this will not allow the electric current to pass through.
Despite all the elements being complete in the circuit, an open circuit will halt the flow of electric current and will not do deliver the necessary energy it is supposed to.
In such a circuit, the wires are cut of and not connected properly.
The reverse is a closed circuit.

Answer:
B. Make the work you do feel easier
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)
