HW 1 Due 2/24/13 – by noon, really at noon. Turn in via SAKAI – do not email it. Turn it into a .pdf file using export or save as. Please do not turn in a .doc or a .docx file. Name your file as follows. Lastname_hw1.pdf - like roman_hw1.pdf A Note about calculations in general, please read. Before turning your work in, it is important to ask yourself whether a calculated answer is within the realm of possibilities, independent of how detailed the calculations required to determine the answer were. For example, if I asked you how long it would take a frozen turkey sitting on your counter to thaw, you could do some fairly complicated calculations. You could consider factors like the temperature of the room, the weight of the turkey, the shape of the turkey, skin or no skin, the humidity, the heat capacity of turkey meat, etc...... If you did a lot of math and got an answer of either 4 seconds or 2 months, you should probably suspect you did something wrong. If your answer was 8 hours, that could seem reasonable given what you've likely observed with popsicles and snowmen. So, the point is, you have to apply some common sense and check your answer. You'll be given more credit on the HW (and in life in general) for admitting your answer seems wrong based on simple logic. Explaining your logic and admitting you got tripped up by the calculation is better than standing by an answer that really make no sense at all. Altimeter measurements. 1) The basic principle of satellite altimetry is similar to that of acoustic echo sounding from ship. A radar pulse is sent out, it reflects off the ocean surface and returns to the satellite. The speed of the pulse and the round trip travel time are then used to determine the distance between the satellite and the sea surface. Lets say the JASON-2 satellite is orbiting roughly 1300 km above the reference ellipsoid of the earth. It sends
