Make a rule: Based on the measured force between objects that are 10 meters apart, how can you find the force between objects that are any distance apart?

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 is the coefficient of kinetic friction μk between the block and the tabletop?

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration
