Concepts and reason
This problem is based on the concept of Nuclear magnetic resonance which involves the absorption of radiations in the radio frequency region. This spectroscopy is generally used for the determination of the type and number of protons present in a molecule.
Fundamentals
A spinning charge creates a magnetic field and therefore behaves as a tiny magnet . The spinning nuclei generate a magnetic field on exposure to an external magnetic field . If an external magnetic field is applied , spinning nuclei can get oriented in two ways:
The magnetic field due to nuclei is in the same direction as the external field. In this case, the nuclei are said to be in a low energy spin state.
The magnetic field due to nuclei is in the opposite direction as the external magnetic field. In this case, the nuclei are said to be in high -energy spin state.

Answer:
3 Hz
The frequency is three waves per second, or 3 Hz.
Natural sources include decomposition,ocean release and respiration.
Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal,oil and natural gas.
