Unprotected exposure to the sun's rays is a factor in the development of skin cancer. Which of the following is an example of empirical evidence that supports this hypothesis? A) An advertisement for a sun block product that claims it protects skin against ultraviolet rays by a certain percentage. B) Data showing a relationship between the amount of sun exposure and the odds of getting skin cancer. C) A skin cancer survivor's recollection that he had a bad sunburn as a child. D) A model of a skin cell showing where DNA is in the cell.

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?

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
