During an investigation about the freezing point of water, Joshua and his group measured the temperature of a cup of liquid water placed in the freezer, every two minutes. The group recorded the different temperatures in a table they created and this happened for the entire class (60
minutes). What type of data did the group collect?
O kinesthetic data
O quantitative data
O qualitative data
O visual data

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.

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
