Answer:
The product of the two numbers is 2.33* 10^13
Explanation:
Given
4.31x10⁷ and 5.41x10⁵
Required
Multiply
The multiplication of the two digits is represented as thus:
This can also be rewritten as
Multiply 4.31 and 5.41
Apply laws of indices
The scientific notation is always in the form:
Where
So:
23.3171 can be rewritten as 2.33171 * 10
So, we have:
Also, apply law of indices again
It's always advisable (but not compulsory to approximate to 1 or 2 decimal places)
So:
<em>Hence; the product of the two numbers is 2.33* 10^13</em>

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>.
Use the formula
Heat= mass x specific heat x temperature increase
