Check all that apply. check all that apply. when two hydrogen atoms are very far apart, the potential energy approaches zero. when the distance between two hydrogen atoms is 0.74 å, a covalent bond is formed. when two hydrogen atoms that are far apart approach each other, the potential energy decreases. at a distance of 0.50 å the potential energy is less than that at 0.74 å. when the potential energy is zero, a covalent bond is formed.

when two hydrogen atoms are very far apart, the potential energy approaches zero.

when the distance between two hydrogen atoms is 0.74 å, a covalent bond is formed.

Explanation:

As we know that the potential energy of two charges is given as

here as the the distance is very large the potential energy is least

at r = infinite

so as two hydrogen atoms comes closer the distance will decrease and hence the potential energy will increase.

So covalent bond is formed when two atoms are close enough so that the equilibrium is achieved

so correct answer will be

when two hydrogen atoms are very far apart, the potential energy approaches zero.

when the distance between two hydrogen atoms is 0.74 å, a covalent bond is formed.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
