Earth science 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. 4. based on your observations, which way does earth rotate—from east to west, or west to east? explain your answer.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
