Answer:
<h2>3920 Joules</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 40 × 9.8 × 10
We have the final answer as
<h3>3920 J</h3>
Hope this helps you
Answer:
Explanation:
silicon has highest ionization energy ionization energy increases from left to right in a period because electron are added to same shell and increase in added electron shield each other poorly from the nuclear attraction
Answer:
Rubidium Sulfide
Explanation:
The chemical name for Rb2S is Rubidium Sulfide
The atomic number of the element is 8 (this is because the atomic number is determined by the muber of protons or electrons). The atomic mass of the element is 16 (this is because the atomic mass is equal to number of protons+number of neutrons
