which is a example of a three dimensional measurement of volume a. 120 cubic meters b. 120 grams c. 120 miles per hour d. 120 units pls help I'm not smart

120 cubic meters

Explanation:

Three-dimensional measurement is basically any unit of measurement cubed. Since grams is just to the first power, it is not considered three-dimensional. miles per hour is a fraction, so it is not a three-dimensional measurement of volume. 120 units are to the first power, so you are left with 120 cubic meters, which is a three-dimensional measurement of volume. Also, another way to solve this is to look at the types of measurement. The cubic meter is a measure of volume. Grams are a measurement of mass. Miles per hour is a measurement of speed. Units can be any type of measurement because you can substitute units instead of any measurement in questions.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
