Light, Reflection and Mirrors 8.
Use the law of reflection and the embedded protractor in order to draw the reflected ray associated
with the given incident ray for the following plane mirror situations. (Markings are provided at 15°
increments.)

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.
