Problem 2: The soil temperature in the upper layers of the earth's surface can vary with changes in atmospheric conditions. Before a cold front arrives, the temperature of the earth's soil near the surface is uniform at 15°C. The cold front stays for 2 days keeping the surface temperature constant at -12°C. The soil properties are: k=0.5W/m.°C and a = 0.15x10 mº/s. What is the temperature...

Problem Solving:(Show all work in every problem) (10 points) The figure shows the bonding of cytosine and guanine. The O-H and H-N distances are each 0.110 nm. In this case, assume that the bonding is due only to the forces along the O-H-O, N-H-N, and O-H-N combinations, and assume also that these three combinations are parallel to each other. (NOTE: Use k =9.00 x 10° Nm2/C) 1. Calculate the net force that cytosine exerts on guanine due to the preceding...

show all calculations and do all parts of the question. Externalities II [Warning, this problem is an enhanced version of a negative externality problem. While I break it down into a series of short steps, it still may take a long time to figure out. Budget accordingly. Don’t skimp on your graph. Your picture will hopefully help you understand what is going on.] High levels of automobile traffic in big cities are incredibly costly to society. Time spent idling in...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
