55kg Olympic diver can jump .65 m high on solid ground. With the help of bouncing on the diving board, she can jump 2.5 m above the board. How much elastic energy is stored in the diving board? (Hint: make the initial situation when the diving board is bent down the most and the final situation when the diver is at her highest point.)​

An uncharged nonconductive hollow sphere of radius 18.0 cm surrounds a 12.0 µc charge located at the origin of a cartesian coordinate system. a drill with a radius of 1.00 mm is aligned along the z axis, and a hole is drilled in the sphere. calculate the electric flux through the hole.

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

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?
