A raindrop initially has mass M_0 = 0.277~\mathrm{g}M 0 =0.277 g and, due to gravity, starts falling from rest through a cloud. One way to model the growth of a raindrop is to assume that its mass grows proportionally to the product of its instantaneous mass and velocity, according to the following equation \dfrac{dM}{dt} = kMV. dt dM =kMV. Here, kk is a constant of proportionality, which we take to be k = 6.99~\mathrm{m}^{-1}.k=6.99 m −1 . What is the speed of the rain drop when its mass has doubled its initial value?

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc
