It’d be B: severe depressive symptoms
Answer:
m
Explanation:
d = separation between the two narrow slits = 1.5 mm = 1.5 x 10⁻³ m
λ = wavelength of the light = 514 nm = 514 x 10⁻⁹ m
D = Distance of the screen from the narrow slits = 5.0 m
w = Distance between the adjacent bright fringes on the screen
Distance between the adjacent bright fringes on the screen is given as
m

Answer:
please read the answer below
Explanation:
To find the electric field you can consider the Gaussian law for a cylindrical surface inside the slab.
where Qint is the charge inside the Gaussian surface, AG is the area of the surface and rho is the charge density of the slab.
By using the formula for the volume of a cylinder you obtain:
where h is the height. If you assume that the slab is in the interval (-zo<z<z0) you can write VG:
Finally, by replacing in the expression for E you get:
hence, for z>0 you obtain E=pz/eo > 0
for z<0 -> E=pz/eo < 0
