Answer:
y = 1.75 cm
Explanation:
In the double-slit experiment the equation for destructive interference is
d sin tea = (m + ½)
λ
let's use trigonometry to find the angle
tan θ = y / L
as all the experiment does not occur at small angles
tan θ = sin θ / cos θ = sin θ = y / L
we substitute
y = (m + 1/2 ) λ L / d
we calculate
y = (3 + ½) 500 10⁻⁹ 5.00 / 0.5 10⁻³
y = 1.75 10⁻² m
y = 1.75 cm
Answer: 44 N/m

Finding the interatomic spring stiffness
Because in our model all the bonds are assumed to be the same, the interatomic spring stiffness ks, interatomic is determined by adding the springs . The details of that addition are below, but the final result is that the interatomic spring stiffness is related to the spring stiffness of the wire like so:

Answer:
No force is generated
Explanation:
Solution:-
- The reason that current carrying parallel wires exert forces between them is that the magnetic field of the one is perpendicular to the velocity of the electrons in the other one (current = moving electrons).
- The magnetic force Fm is given by the cross product of velocity vector (v) and strength of magnetic field (B):
Fm = q* ( v x B ).
- In perpendicular (current carrying) wires, the magnetic field of one wire is in parallel with the velocity of the electrons in the other one, and, thus, no force is generated.
Fm = q * // ( v x B )
= q * ( 0 ) = 0
- The cross product of parallel vectors is zero.
<h2>Answer:</h2>
No, interference patterns will not be observed as the two sources of light are neither monochromatic neither coherent and therefore interference of light will not form total reinforcement or total cancellation at any point
