Answer:
951 Gaspra orbits the Sun near the inner edge of the main asteroid belt between Mars and Jupiter. Gaspra was named by its discoverer Neujmin for a resort on the Crimean peninsula. Consequently, many of the asteroid's craters have been named for resorts and spas worldwide.

Answer:
The correct option is energy levels
Explanation:
Rutherford's model of an atom suggests that an atom has a tiny positively charged central mass (now called the nucleus) which is surrounded by electrons (negatively charged) in a <em>cloud</em>-like manner.
Bohr's model went a bit further than the Rutherford's model in describing an atom by suggesting that the electrons which surrounds in the nucleus travel in <u>fixed circular orbits</u>. This description by <em>Bohr was able to describe the energy levels of orbitals which assumes that smallest orbitals have the lowest energy while the largest orbitals have the highest energy</em>.
Answer:
<em>The total surface area of the seven little spheres is 1.91 times the total surface area of the bigger sphere.</em>
Explanation:
<u>Volume of a Sphere</u>
The volume of a sphere of radius r is given by:
The volume of each little sphere is:
When the seven little spheres coalesce, they form a single bigger sphere of volume:
Knowing the volume, we can find the radius rb by solving the formula for r:
Multiplying by 3:
Dividing by 4π:
Taking the cubic root:
Substituting:
The surface area of the seven little spheres is:
The surface area of the bigger sphere is:
The ratio between them is:
The total surface area of the seven little spheres is 1.91 times the total surface area of the bigger sphere.
