Micah lives near some small cliffs. One day, he finds a fossil in a layer of sedimentary rock. He does not know what kind of fossil it is or how old it is. He wants to know more about the fossil.
How can Micah best estimate how old the fossil is?
O A. Compare the fossil to organisms alive today and identify differences.
OB. Observe the characteristics of the fossil and other fossils in the same rock layer.
O C. Calculate how long it would take geologic processes to form the rock layer with the fossil.
O D. Compare the position of the fossil with the positions of any surrounding rock layers that have known ages.

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?

If a stone with an original velocity of 0 is falling from a ledgeand takes 8 seconds to hoybthe ground whays the final velocity of the stone
