Newtons laws Elephant and Feather - Free Fall
Assume that an elephant and a feather are dropped off a extremely tall building from the similar height at the similar time. Assume also in which air resistance could somehow be eliminated such in which neither the elephant nor the feather would experience any air drag during the course of their fall. Which object - the elephant or the feather - will hit the ground first? The animation at the right accurately depicts this situation. The motion of the elephant and the feather within the absence of air resistance is shown. Additionally, the acceleration of each object is represented through a vector arrow.
Q. Find the minimum wavelength of X-rays produced by an X-ray tube operating at 1000 kV. λmin = 12400 A 0 / V Therefore λmin = 12400 X 10 -10 / 10 6 = 0.0124 A 0
