D. Copper and Gold
Copper and gold are used a lot in electrical applications.
Air and wood are insulators and glass is also kinda bad...
Answer:
d y / x = m λ
Explanation:
When the laser beam, which is a coherent light, hits the slits, part of each beam passes through each slit.
When this is observed on a screen that is quite far from the slits, a series of intense linear separated by dark areas. The explanation for this distribution of the light pattern is that when adding the rays that come out of the slits they travel different distances, which introduces a difference in optical path and if this difference is an integer multiple of the wavelength, a bright line
d sin θ = m λ
Where d is the distance between the slits (0.1 mm)
Also, since the angle of the measurements is small, we can approximate the tangent
tan θ = y / x = sin θ /sin θ
sint θ = y / x
Substituting into the equation
d y / x = m λ
This expression gives the location of the bright lines on the screen

Answer:
option C
Explanation:
Let mass of the bullet be m and velocity be v
mass of gun be M and bullet be V
now,
using conservation of momentum for gun 1
(M+m) V' = 2 mv + 3 MV
V' = 0
3 M V = - 2 mv
momentum of gun 1 =- 2 mv---------(1)
now for gun 2
(M+m) V' = mv + MV
V' = 0
M V = - mv
momentum of gun 1 = -mv-----------(2)
dividing equation (1) by (2)
the correct answer is option C
