Answer 2

Answer:

U.S.A. Planck's constant h is often considered a fundamental parameter of the Universe. Its value in the MKS (meter-kilogram-second) system is 6.626×10−34 joule-sec. The notable fact is that Planck's constant is dimensional and hence its magnitude depends upon the system of units used to express it.
