Answer:
d.Electric flux through a closed surface and charge enclosed by the surface
Explanation:
Gauss' Law states that the electric flux through a closed surface is equal to the total charge enclosed by that surface divided by the electric permittivity.
Therefore, correct answer is d.
a -> Ohm's Law.
b -> Faraday's Law.
c ->
Mass is the scalar quantity. (A)
Velocity, force, and acceleration are vectors.
Answer:
There is a dependency relationship between the refractive index of each substance and the radiation wavelength.
The refractive index in a given medium is inversely proportional to the wavelength of a color.
For example:
The rays of the red color have a wavelength greater than the rays of the blue color, therefore they have a lower refractive index and consequently a light scattering less than the blue.
Snell's law :
n₂/n₁ = v₁/v₂ = λ₁ /λ₂
*n: (refractive index)
v: (speed of light propagation)
λ: (wavelength)
Answer:
184 Km
Explanation:
given,
speed of S wave = 4.50 Km/s
speed of P wave = 7.80 Km/s
reading time difference = 17.3 s
we know,
distance = speed x time
time taken by s-wave
time taken by the P-wave
now,
t₁ - t₂ = 17.3 s
3.3 x = 607.23
x = 184 Km
distance of the focus from the station is 184 Km.
