read the following hypothesis about why a chicken bone becomes bendy after being soaked in vinegar:

the bone can bend because the acid in the vinegar has removed the calcium that made it hard.
what evidence would support this hypothesis?
a. observing that a bone placed in a freezer becomes more rigid
b. observing that a bone placed in a beaker of acid becomes bendy
c. observing that a bone placed in a beaker of water becomes bendy
d. observing that a bone placed in a mixture of baking soda and water becomes more rigid

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?
