Now suppose that all of the hydrogen atoms in the sun were converted into helium. how much total energy would be produced? (to calculate the answer, you will have to estimate how many hydrogen atoms are in the sun. this will give you good practice with scientific notation, since the numbers involved are very large! see appendix c for a review of scientific notation.)

Erosion of the beach is normally a slow process. however, in certain situations, large chunks of shore may wash out to sea. what could cause this to happen?

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?
