Achild holds up a silver spoon and is surprised to see her reflection there.
which interaction between light and matter explains this?
a.
when light hits something relatively flat, smooth, and shiny, it is transmitted by the surface, allowing nearby objects to be seen on the surface.
b.
when light hits something relatively flat, smooth, and shiny, it is refracted by the surface, allowing nearby objects to be seen on the surface.
c.
when light hits something relatively flat, smooth, and shiny, it bounces off the surface, allowing reflected objects to be seen on the surface.
d.
when light hits something relatively flat, smooth, and shiny, it is absorbed by the surface, allowing refracted objects to be seen on the surface.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
