Unformatted text preview: 31. The mass density of the candy is = m 0.0200 g = = 4.00 104 g/mm3 = 4.00 104 kg/cm3 . 3 V 50.0 mm If we neglect the volume of the empty spaces between the candies, then the total mass of the candies in the container when filled to height h is M = Ah, where A = (14.0 cm)(17.0 cm) = 238 cm 2 is the base area of the container that remains unchanged. Thus, the rate of mass change is given by
dM d ( Ah) dh = = A = (4.00 104 kg/cm 3 )(238 cm 2 )(0.250 cm/s) dt dt dt = 0.0238 kg/s = 1.43 kg/min. ...
