Answer:
its an insulator
Explanation:
they block electricity from passing
To determine the values the total mechanical energy of the
given problem we can first identify the values given
Given are:
<span><span>1.
</span>Kinetic Energy = 5.2 Joules</span>
<span><span>2.
</span>Potential Energy = 3.5 Joules</span>
Solution:
The formula for mechanical energy is
<span><span>
a.
</span>Mechanical energy is total energy of both
kinetic and potential hence,</span>
<span><span>
i.
</span>ME = PE + KE</span>
<span><span>
ii.
</span>ME = 3.5 + 5.2</span>
<span><span>
iii.
</span>ME = 8.7 Joules</span>
Standard:560,000
Short form: 560 thousand
Word form: Five hundred six hundred thousand
Expanded form: 500,000+60,000
Atomic number is protons + electrons
Mass number is protons + neutrons
So to calculate the number of neutrons, you do
atomic number - atomic mass
31 - 84 = - 53
