EARTH SCIENCE PLEASE ANSWER
1. How would you describe the movement of the sun over 30 minutes? What direction does it appear to move?
2. You have sticks planted in the ground that you are using as basic sundials. One is 2 m long; the other is 5 m long. Does the length of the stick affect how much the shadow mark moves, or do both shadows move evenly? Explain your answer.
3. How would the length of the shadow at noon compare with the length of the shadow in the late afternoon or early morning? Explain your answer.

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.
