Number the statements listed below in the order that they would occur in engine operation. then, label these stages as intake, compression, power, or exhaust. a. the fuel mixture is ignited by the spark plug, and the resulting explosion forces the piston down in the cylinder. b. the piston rises and compresses the fuel mixture in the combustion chamber. c. the exhaust gases left over from the combustion are released from the cylinder. d. a mixture of air and fuel is drawn into the cylinder.

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
