the number of electrons that fill the outer shell determines the properties of elements
F = q₁q₂C / r²
F force
q charge
C Coulomb constant
r separation between charges
Sample Response: The water is cooler than the sand because it has a higher specific heat value. This means that it takes longer for the water to increase in temperature, making it feel cooler than the sand, which warms up more quickly.
The bouncy ball experiences the greater momentum change.
To understand why, you need to remember that momentum is actually
a vector quantity ... it has a size AND it has a direction too.
The putty and the ball have the same mass, and you throw them
with the same speed. So, on the way from your hand to the wall,
they both have the same momentum.
Call it " M in the direction toward the wall ".
After they both hit the wall:
-- The putty has zero momentum.
Its momentum changed by an amount of M .
-- The ball has momentum of " M in the direction away from the wall ".
Its momentum changed by an amount of 2M .
The answer is Caribbean Sea south of San Juan, Puerto Rico. A protectorate,
in its beginning accepted by modern international law, is a reliant territory
that has been arranged local independence and some individuality while still remembering
the suzerainty of a better sovereign state.
