Atrain is traveling at 30.0 m/s relative to the ground in still air. the frequency of the note emitted by the train whistle is 262 hz. the speed of sound in air should be taken as 344 m/s. what frequency (f approach) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and approaching it? what frequency (f recede) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and receding from it?

Intro: a solid ball of radius rb has a uniform charge density Ο. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of Ο, rb, r, and Ο΅0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of Ο, rb, r, and Ο΅0. part c: let e(r) represent the electric field due to the charged ball throughout all of space. which of the following statements about the electric field are true? check all that apply. e(0) = 0 e(rb)=0 limrββe(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as rββ.
