WILL MARK BRANLIEST! Explain what is happening when the girl is at each point. **The girl has started at 1 and goes to 4.

Drag & Drop

1. gaining kinetic. 2. most kinetic. 3. gaining potential 4. most potential.

1 is the most potential energy, 2 is gaining potential energy, 3 is most kinetic energy, and 4 is gaining potential energy.

Explanation:

did anyone actually do this? like if anyone has submitted this i rly need .

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
