Give a calculate answer to show that the two values (english system and metric system) for the planck constant are equivalent.
h=4.14*10-15 (ev-sec) or 6.63*10-34( joule-sec)

Why are biogeochemical cycles important? earth is a closed system. that means the amount of rocks, metals, carbon, nitrogen, oxygen, and water on so, it is essential that biogeochemical these materials as they move through earth's subsystems.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b. b. at twice the distance, the magnitude of the field is 2b. c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
