Two loud speakers are located 4.00 m apart and are playing an in phase tone of 97.0 hz which under conditions of a nominal speed of sound of 340.0 m/s has a wavelength of
3.51 m.
How far from the left speaker would you need to stand to hear the tones from the
two speakers cancel out so that you would hear nothing?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

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
