They put gaps between the particles to slow down conduction
They make the material thicker so energy has to travel a further distance.
Here in all nuclear reactions we can say that mass conservation and charge conservation is always true
Here iron nuclei smashed into lead nuclei and then a new nuclei will form which will released along with a neutron
Now in this reaction mass and charge will remain conserved
mass number of iron + mass number of lead = mass number of new nuclei + mass number of neutron
58 + 208 = x + 1
x = 265
so the new nuclei formed will have mass number A = 265
now we will use charge conservation
Number of protons in iron + number of protons in lead = number of protons in new nuclei + number of protons in neutron
26 + 82 = z + 0
z = 108
so the new nuclei will form with atomic number z = 108 and mass number A = 265
If we refer periodic table to find such atom we will see that this is 
so the new nuclei formed is 
The current is
(120v) / (the resistance of the stove in ohms) .
The unit of the current is Amperes.
Gravity or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another. - google
A rotation motion is a motion that takes place around a fixed axis.
Like gears turning on each other.
