Answer is C: Hazard Communication
Hazard Communication Hazard (HCS 2012) provides a coherent and standardized approach to communicating the hazards of chemicals by way of Safety Data Sheets (SDSs) and labels on containers. However, Occupational Safety and Health Administration (OSHA) revised its HCS 2012. In it, they revised criteria for classification of chemical hazards, labeling provisions, hazard statements, and precautionary statements. In addition, modifications were made to health standards substances to ensure requirements for labels and SDSs are consistent with the HCS 2012. According to OSHA’S standards, SDSs should periodically be reviewed and updated.
Answer:
A. simple to construct and easy to repair
Explanation:
A dynamic microphone works on the principle of electromagnetic principle. A diaphragm is attached to a coil of wire which helps in producing sound. Responding to the sound waves, the coil of the wire is vibrated by the diaphragm. A magnetic field is created by the magnet which is present inside the coil of wire. The electrical signal is generated in response to the motion of the coil. The speed of the motion produces the amount of the current.
Since the construction of a dynamic microphone is easier as compared to any other microphone, John is likely to opt to build one.
Answer: 5G high bands (mmWave, also referred to as FR2) are found in the range of 24GHz to 40GHz. They deliver large quantities of spectrum and capacity over the shortest distances
