Aperson is involved in a car crash and has a momentum of 2,050 kg*m/s. if the airbag deploys, the impact will occur over 0.1 seconds. if the airbag does not deploy, the impact will occur over 0.01 seconds. how will the impact force change if the airbag does not deploy?

Explain to someone who knows nothing about fossils the study of invertebrate paleontology and how it scientists understand the history of the earth. be sure your explanation contains a minimum of two complete sentences.

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

What are similarities and differences between refraction, reflection, diffraction and absorption?
