An electric dipole is formed from +/- 5.0 nc point charges spaced 3.0 mm apart. the dipole is centered at the origin, oriented along the y-axis. part a what is the electric field strength at point (x, y) = (25 mm, 0 cm)? express your answer using two significant figures. part b what is the electric field strength at point (x, y) = (0 cm, 25 mm)? express your answer using two significant figures.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
