Suppose on a nice december evening you gaze upon your favorite star. you stick your handout into the sky and point at it, then you keep your arm fixed and frozen. until 6 months later when you reach for the sky again and point at your star with your other arm. suppose now you observe the angle you have created with your arms to be 0.06o. how far is the star from the sun? [hint: assume the earth orbits in a circular motion around the sun once every 12 month, where the orbit has radius of r=149.6×106kmr=149.6×106km ]

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
