A. C = 1/√𝜇0𝜀0
-
B. None of these
-
C. C = 1/𝜇0𝜀0
-
D. C = 𝜇0𝜀0
Explanation
Maxwell's equations led to the derivation of the speed of electromagnetic waves, including light.
The speed of light (c) is given by C = 1/√μ₀ε₀, where μ₀ is the permeability of free space and ε₀ is the permittivity of free space.
میکس ویلین اسپیڈ ڈسٹری بیوشن _____ کی براہ راست وضاحت فراہم کرتا ہے؟
-
A. None of these
-
B. Evaporation
-
C. Heat
-
D. Thermal expansion
Explanation
- The Maxwellian speed distribution describes the distribution of molecular speeds in a gas.
- This showing that some molecules have enough kinetic energy to escape the liquid surface.
- This explains evaporation, where faster-moving molecules overcome intermolecular forces and leave the liquid phase.
