What happened as Leah and Isaac moved down the small slope from point C to D?
Sedbober [7]

Answer:

D

Explanation:

As you move down anything, towards the earth, (gravitational) potential energy decreases. This eliminates options B and C.

By the law of conservation of energy, the energy of the system stays the same. However the energy may be converted into different forms. In this case, the potential energy is converted into kinetic energy - this is what makes people move faster as they go down the slope. This makes option A wrong and option D right.

How many total orbitals are within the 3s, 3p, and<br> energy level?
Nina [5.8K]

The answer for the following question is explained below.

Therefore the total number of orbitals are " 9 ".

Explanation:

Orbital:

An orbital is a mathematical function that describes the wave-like behavior of an electron,electron pair,or the nucleons.

The total number of orbitals present in the 3rd energy level is 9.

Here,

A 3 s subshell has only one orbital.

A 3 p subshell has three orbitals.

A 3 d subshell has five orbitals.

Therefore the total number of orbitals is:

3 s = 1 orbital

3 p = 3 orbitals

3 d = 5 orbitals

total orbitals in 3rd energy level is = 1 + 3 + 5 =9

Therefore the total number of orbitals are " 9 ".
