At first, wave A and wave B are identical. Then, wave A passes through a wooden table and wave B passes through a swimming pool. Which of the following is true about the waves AFTER they encountered different media? Wave A and B have the same speed.

Wave B has a faster speed than wave A.

Wave A has a faster speed than wave B.

There is not enough information to tell.

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?

Which of the following are appropriate acceleration units?
