NASA lost contact with Pioneer 10 on January 22, 2003. How far in meters was it from the sun on that date? Pioneer 10 was traveling at 12.24 km/s relative to the sun. Calculate the position of Pioneer 10 as of January
2009 relative to the sun. Pioneer is headed toward the star Aldebaran in the constellation Taurus. Find the
distance from the sun to Aldebaran in meters; make a logarithmic scale; and plot the positions of Aldebaran,
Pioneer 10 as of January 2003, and Pioneer 10 as of January 2009. At 12.24 km/s, how many years will it take
Pioneer 10 to reach Aldebaran? (Note: time = distance/velocity, 1 year = 3.16 × 107
s.) Show your calculations
and your graph.

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
