Final answer:
The explosive power of an airbag can cause harm and fatalities to passengers. There is no specific height under which an airbag becomes deadly. Proper installation of airbags and seat belt usage are important for passenger safety.
Step-by-step explanation:
The explosive power of an airbag has the potential to cause harm and even fatalities to passengers, particularly children and elderly adults. However, there is no specific height or size at which an airbag becomes deadly. The force exerted by an airbag depends on various factors such as the speed of the collision, the size of the occupant, and their proximity to the airbag. It is crucial to install properly functioning airbags and ensure that passengers are seated correctly and use seat belts to minimize the risk of injury during a collision.
