Esuelve los siguiente Si una caja de metal está sobre una pista de hielo,
¿cuánto trabajo se realizará sobre ella si se aplica
una fuerza de 800 N desplazándola una distancia
de 10 metros?

Trabajo realizado = 8000 Nm

Explanation:

Dados los siguientes datos;

Fuerza = 800N

Distancia = 10 m

Para encontrar el trabajo realizado;

Sustituyendo en la ecuación, tenemos;

Trabajo realizado = 8000 Nm

"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."

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
