Question

the the four example for Dimensionless constant​

Answer 1

Answer:

Dimensionless fundamental physical constants include: α, the fine structure constant, the coupling constant for the electromagnetic interaction (≈ 1⁄137). Also the square of the electron charge, expressed in Planck units, which defines the scale of charge of elementary particles with charge.
