This wave is 0.0825 m a sinusoidal transverse wave travels along a long stretched string. the amplitude of its frequency is 4.49 hz, and its wavelength is 1.35 m (a) what is the shortest transverse distance between a maximum and a minimum of the wave? number (b) how much time is required for 69.1 cycles of the wave to pass a stationary observer? number (c) viewing the whole wave at any instant, how many cycles are there in a 39.3-m length of string

Intro: a solid ball of radius rb has a uniform charge density ρ. 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 ρ, rb, r, and ϵ0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of ρ, rb, r, and ϵ0. 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 limr→∞e(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as r→∞.
