How does the density of ice compare to that of liquid water and why is that property important to aquatic organisms? (1 point)
a. the density of ice is higher than that of liquid water, which means that ice forms from the bottom of lakes upward, protecting aquatic life in winter.
b. the density of ice is lower than that of liquid water, which means that ice forms from the top of lakes downward, protecting aquatic life in winter.
c. the density of ice is higher than that of liquid water, which means that ice forms from the top of lakes downward, protecting aquatic life in winter.

Let v1, v2, w be three linearly independent vectors in r 3 . that is, they do not all lie on the same plane. for each of the following (infinite) set of vectors, carefully sketch it in r 3 , and determine whether or not it is a vector space (i. e., a subspace of r 3 ). explain your reasoning

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)
