Lucia has a bedroom window that gets direct sun in the afternoon and her room gets hot. She puts some mylar (a shiny plastic) on the outside of her window. 1. How might this change the temperature in her room? Use what you know about light to explain your answer.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
