Anuclear reactor is:
a. constructed from thick aluminum walls that can control the nuclear reactions
b. surrounded by a thick pressure vessel that is filled with a cooling fluid
c. powered by a combustion chamber in which uranium is burned
d. superheated by water until the control rods are set into motion

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

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.

Area around a charged object where the objects can exert a force on another charged objects is an electric
