Answer:
462 nm
Explanation:
Given: width of the slit, d = 5.6 × 10⁻⁴ m
Distance of the screen, D = 4.0 m
Fringe width, β = 3.3 mm = 3.3 × 10⁻³ m
First dark fringe means n =1
Wavelength of the light, λ = ?
Answer:
30.95°
Explanation:
We need to define the moment of inertia of cylinder but in terms of mass, that equation say,

Replacing the values we have,


At the same time we can calculate the mass moment of intertia of cylinder but in an axial way, that is,



Finally we need to find the required angle between the fixed line a-a (I attached an image )

Replacing the values that we have,





Answer:
Explanation:
At the submicroscopic and microscopic levels temperature is proportional to the average degree of kinetic energy of the particles of a substance
Answer:
Thermosphere
temperature continue to rise up to 1500*C
Ionosphere
Mesosphere
temperature falls to -93*C
Stratosphere
protective ozone layer
UV radiation causes temperature to rise
Troposphere
78% nitrogen, 21% oxygen
temperature drops from 17 to -52*C
Explanation:
Something that is not magnetic
