Answer:
B. Increase the mass of one of the objects.
E. Decrease the distance between the objects.
Explanation:
To effect an increase in the gravitational force between two objects, the mass of both objects should be increased and the distance between them reduced.
This is derived from the Newton's law of universal gravitation:
- It states that "the force of gravity between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them".
Therefore, if the mass of the two bodies are increased and the distance between them reduced, the gravitational force of attraction will increase.
A
single oxygen has atomic number 8 that means the nuclei of all oxygen atoms
have eight protons. The number of minus-charged electron is two but the number
of electrons is 10. <span>To gain a minus two-charge ion, it
must have two more negative electrons than positive charged protons. With this,
the ion has 10 electrons, which give it a -2 net charge. </span>
