Which of the following statements is false?

question 5 options:

a: destructive interference occurs when the crest of one wave overlaps the trough of another and their individual effects are reduced or cancelled out.

b: when the crest of one wave overlaps the crest of another, their individual effects add together, which is constructive interference.

c: constructive interference occurs when the crest of one wave overlaps the trough of another and their individual effects are reduced or cancelled out.

d: for sound waves, destructive interference results in lower volumes.

To understand the electric potential and electric field of a point charge in three dimensions consider a positive point charge q, located at the origin of three-dimensional space. throughout this problem, use k in place of 14? ? 0. part adue to symmetry, the electric field of a point charge at the origin must point from the origin.answer in one word.part bfind e(r), the magnitude of the electric field at distance r from the point charge q.express your answer in terms of r, k, and q. part cfind v(r), the electric potential at distance rfrom the point charge q.express your answer in terms of r, k, and q part dwhich of the following is the correct relationship between the magnitude of a radial electric field and its associated electric potential ? more than one answer may be correct for the particular case of a point charge at the origin, but you should choose the correct general relationship. a)e(r)=dv(r)drb)e(r)=v(r)rc)e(r)=? dv(r)drd)e(r)=? v(r)r
