Physicist s. a. goudsmit devised a method for measuring the mass of heavy ions by timing their period of revolution in a known magnetic field. a singly charged ion makes 5.00 revolutions in a 50.0 mt field in 1.11 ms. calculate its mass, in atomic mass units.

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?

What are similarities and differences of reflection, refraction, diffraction and absorption?
