An electron moves in a straight path with a velocity of +500,000 m/s. it undergoes constant acceleration of +500,000,000,000 meters per second per second. how far will the electron have traveled when it reaches a velocity of +675,000 m/s? a. +0.175 m b. +0.35 m c. +0.21 m d. +0.41 m

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.

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.
