The velocity of a wave is
a. its direction and speed.
b. the distance between two wave crests.
c. the time required for a wave to move one wavelength.
d. half the vertical distance between a crest and a trough divided by the frequency.

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 os the equation of the line described below written in slope-intercept form? the line passing through point (0,0) and parallel to the line whose equation is 3x+2y-6=0

If you let go of the notebook after lifting it, will it move? how?
