The students continued their experiments with chi electrostatics. Joe and Lashonda each blew up a balloon and then
rubbed their dry hair with the inflated balloons. While they did this
the other students notice that their hair was starting to stick straight
out. Next they tied a string to their balloons and let them dangle next
to each other. Predict what will happen.
A)
The balloons will separate because friction has given
each an overall negative charge.
B)
The balloons will move together because the
balloons have gained charge from friction.
C)
The balloons will attract each other because one is
positive and the other is negative.
The balloons have each gained positive charge from
D) friction and like charges attract so they will come
together

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
