Suppose a planet has half the mass of Earth but
the same radius. An astronaut stands on the surface
of the planet and drops a rock from a height of

hit the ground on that planet than it would on
Earth?
(a) 1.2 times longer
(b) "2 times longer
(c) 2 times longer
(d) 4.8 times longer

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.
