Explanation:
"The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution. A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute."
Because they have different density (density of feathers < density of nails)
Jupiter
Ganymede orbits Jupiter.
The smaller the displacement, the smallest restoring force it will create.
As seen from the figure given below, The spring system follows the equation,
F = -Kx
where, x is the displacement
F is the restoring force
k is the spring constant
If , K is kept constant, then,
F is directly proportional to the displacement but it acts in opposite direction due to negative sign.
