Plz hurry! ! i need now! like no joke! plz me now! 20 points + brainliest! as one of america’s leading experts on deep-space debris, the president has asked you to brief him on the dangers posed to earth by asteroids and meteoroids. write a one-page briefing to the president explaining why you do (or do not) believe that asteroids and meteoroids are a grave threat during the current administration, and what evidence scientists have to support your point of view.

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
