Answer:
Gravitational force is directly promotional to the mass
of both interacting objects.
Explanation:
More massive objects will attract each other with
a greater gravitional force. So as the mass of the
either objects increases the force of gravitational
attraction between them also increases.
Answer:
A conductor is a material that permits electrons to effortlessly go through it. Copper is a good conductor. Note that the valence shell has just a single electron.
While;
Materials that don't conduct are named insulators.(i.e. glass, porcelain, plastic, elastic. The covering on electrical wire is an insulator.)
Insulators don't conduct since they have a full or almost full valence shell and along these lines their electrons are firmly bound.
Explanation:
According to Bohr Rutherford model of Atom, An Atom contains three essential particles; Protons and neutrons that make up the nucleus and the electrons that circle or orbit the nucleus. The electrons circle the nucleus.

Example of correct chemical formula is Al2O3
Explanation
Al2O3 is correct because Aluminium (Al) has a valence of three(3) while oxygen(O) has a valence of two (2) . when writing a chemical formula one start with cation(POSITIVELY CHARGED) symbol followed by anion symbol (negatively charged). The valence number are interchanged between cation and anion and are then written as subscript.
Answer:
In the case of the Hardwood floor vacuum, you have to use a vacuum cleaner to clean hardwood floors. If you use a hard-bristled broom, it can damage the exterior of Hardwood floors. On the other hand, the vacuum creates less airborne dust and doesn't damage the surface of hardwood floors.When done correctly, the vacuuming process can remove more soil from a floor than a dust mop or broom. ... “The vacuum sucks up and removes all the dust, even the fine dust. It removes all the soil.” Vacuums typically do a better job than mops at reaching dirt in cracks and corners
Explanation:
hope this helps
