Answer :
The range of speeds considered to be "severe impact speeds" can differ based on context, such as tornadoes or vehicle crashes. Severe tornadoes have wind speeds that can exceed 200 mph, and vehicle impacts are generally severe above 40-45 mph. Hence, the correct answer is C.
The term "severe impact speeds" can refer to the speed of various phenomena such as wind in tornadoes, vehicles in crashes, or any other context where high speeds can cause severe impact or damage. To determine the range of speeds that are considered to be "severe impact speeds," we need a context. In the context of tornadoes, the Enhanced Fujita Scale, or EF-scale, is used to categorize tornadoes by the damage caused, and wind speed is a significant factor in this. Severe tornadoes (EF4-EF5) have wind speeds ranging from 166-200 mph (EF4) and above 200 mph (EF5). These speeds would certainly be considered severe.
If we refer to vehicular accidents, "severe impact speeds" could vary based on the type of vehicles involved and the situations. However, any speed that can cause significant damage to vehicles and serious injury or fatality would usually be considered "severe." Often speeds above 40-45 mph could result in severe impacts, depending on the circumstances.
Final answer:
The range of speeds that are considered to be "severe impact speeds" fall under the topic of kinematics in Physics.
