Suppose a baseball player steps to the plate with the intention of trying to "coax" a base on balls by never swinging at a pitch. the umpire, of course, will necessarily call each pitch either a ball (b) or a strike (s). what outcomes make up the event a, that a batter walks on the sixth pitch? (note: a batter "walks" if the fourth ball is called before the third strike.) larsen, richard j.; marx, morris l.. an introduction to mathematical statistics and its applications (page 19). pearson education. kindle edition.

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

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
