1. 2. Harry Potter is chasing a snitch on his Nimbus 2000 broom moving at 0.6c. Hermione, wearing her time turner is sitting in the stands watching Harry. When Hermione sees Harry closing in on the snitch she would observe his broom to be and he would observe her time turner spinning. a. b. C. d. shorter, slower longer, slower shorter, faster longer, faster When the day comes that our sun exhausts most of the hydrogen fuel in its core, it will enlarge and turn from yellow (or white) to red, becoming a red giant. What can be concluded about the surface temperature, energy density, and intensity (power per unit area) of our sun once it becomes a red giant? a. b. Temperature decreases, energy density decreases, intensity increases Temperature decreases, energy density decreases, intensity decreases C. Temperature increases, energy density increases, intensity increases Temperature increases, energy density increases, intensity decreases d.
