What three components are needed for air bag activation?

The correct response highlights the essential factors that contribute to airbag activation, specifically focusing on the dynamic conditions under which an airbag deploys during a collision.

Speed is crucial as it determines the force of impact; airbags are designed to deploy when the vehicle experiences sufficient deceleration, signaling an accident. The 12 V power supply is essential because airbags rely on electrical systems to initiate deployment; without the power, the system cannot function. Lastly, pitch and yaw address the angles at which a vehicle impacts objects, which are important for determining the necessary deployment of the airbag. Essentially, if the vehicle encounters a significant impact at specific angles, the airbag needs to activate to protect the occupants.

The other options do not encompass the right combination of factors needed for airbag deployment. For instance, factors like pressure, temperature, and various distances do not directly correlate with how modern airbag systems are triggered during a crash. Understanding these components helps in grasping the complexities of vehicle safety systems and their operation during high-impact scenarios.
