Silicon is a metalloid (:
Answer:
6000 lines/cm
Explanation:
From the question we are told that:
Grating 1=4000 lines/cm
Grating 2=6000 lines/cm
Generally The Spread of fringes is Larger when the Grating are closer to each other
Therefore
Grating 2 will spread the the light through a larger angle in the first-order pattern because its the closest with 6000 lines/cm

Answer: ![3.5\ km](https://tex.z-dn.net/?f=3.5%5C%20km)
Explanation:
Given
Car starts from the state of rest and acquires a velocity of
in 6 minutes
Final velocity in m/s is ![v=70\approx 19.44\ m/s](https://tex.z-dn.net/?f=v%3D70%5Capprox%2019.44%5C%20m%2Fs)
Using equation of motion
![v=u+at\\\Rightarrow 19.44=0+a(6\times 60)\\\Rightarrow a=0.054\ m/s^2](https://tex.z-dn.net/?f=v%3Du%2Bat%5C%5C%5CRightarrow%2019.44%3D0%2Ba%286%5Ctimes%2060%29%5C%5C%5CRightarrow%20a%3D0.054%5C%20m%2Fs%5E2)
Distance covered in 360 s
![\Rightarrow v^2-u^2=2as\\\Rightarrow 19.44^2-0=2\times 0.054\times s\\\Rightarrow s=3500.64\ m\approx 3.5\ km](https://tex.z-dn.net/?f=%5CRightarrow%20v%5E2-u%5E2%3D2as%5C%5C%5CRightarrow%2019.44%5E2-0%3D2%5Ctimes%200.054%5Ctimes%20s%5C%5C%5CRightarrow%20s%3D3500.64%5C%20m%5Capprox%203.5%5C%20km)
