Andy is walking around the 100 meter track that has the start line on the west side of the field and has the 100 meter finish mark on the East side of the field. If it starts at the 5.00 m mark and then travels to
the 8.00 m mark, what is its distance and displacement?

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?

Which two particles are found in the center of an atom

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
