Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a
50 kg ball traveling at 10 m/s,
A 50 kg ball traveling at 20 m/s would have
kinetic energy
A 50 kg ball traveling at 5 m/s would have
kinetic energy
A 50 kg person falling at 10 m/s would have
kinetic energy

the answer is 0.42 is that is an option. this question provides no info

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
