A.5 [kg] cube of aluminum at 10.0 [°c] is dropped into water at 30 [°c]. the specific heat of the water is 4186 [j/(kg °c)], the specific heat of aluminum is 900 [j/(kg °c)]. after a few minutes the final temperature of the water (with the aluminum cube in it) (a) assuming no heat is lost and assuming that the effects of the container can be neglected, what is the mass of the water just before the aluminum cube was dropped in? was measured as 28.98 [°c]. 1p (b) what was the volume of the aluminum cube in [m2] and in [em'] if the density of aluminum is 2830 (ko/m212 lp

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
