The ball has to push things out of its way in order to keep going.
For example:
-- billions of air molecules
-- hundreds of blades of grass .
-- To push something out of its way, the ball exerts a force against the
obstacle, and pushes it some distance.
-- A force acting through a distance is 'work', and that means 'energy'.
-- The ball has a certain amount of energy ... the amount you gave it
when you kicked it. It gives every air molecule and blade of grass a
little bit of energy, so the ball has less and less as it goes along.
-- Eventually, it has no more energy to use to push things out of the way.
No energy means no motion, so it stops.
-- If it were in space where there are no air molecules and no grass,
it would go on forever.
Is this your Question:
Read the hypothetical situation below and answer the question that follows.
In response to criticisms that the King of Mordor has failed to gain the consent of his people, the King claims that he does in fact represent the consent of the people because without their King, society would crumble into chaos.
Which statement BEST represents a rebuttal that Rousseau would use to counter the King's argument?
A.
Absolute chaos is preferable to the absolute power of the King.
B.
The King of Mordor should establish a system of checks and balances.
C.
If the King of Mordor were to represent the will of his people, then he would at least provide the public services demanded by his people.
D.
It is impossible for the King of Mordor to have the consent of the people because the monarchy is not a freely formed government in which the people have a say in how it operates.

Explanation:
Rousseau believed that sovereignty (the power to make laws) belonged to the people, not one person, and that it should be carried out by a representative body of the people who are elected by them on their behalf. While he agreed society requires a ruler(s), he thinks they should be chosen by the people.
Answer:
Radius of bigger loop(R) =4.5cm
Explanation:
Consider a circular path of radius r around the wire. The magnetic field along that path is given by
;
∫B*dl = k*I where I is the current enclosed. From symmetry, ∫B*dl = 2*π*r*B
B = K*I/r, so the magnetic field varies inversely as the loop radius and directly as the current.
The smaller loop current to radius ratio is 12/2.7
The bigger loop current to radius ratio is = 20/R
12/2.7 = 20/R
R = (20 * 2.7)/12
R=54/12
R=4.5cm
Answer:
v=2.42m/s
Explanation:
We use the energy conservation theorem in order to solve the problem. The energy when the spring is compressed is equal at the energy when the disk leaves the spring:
At the beginning the initial energy is totally potential, energy linked to the compressed spring. At the end the energy is totally kinetics
We solve the equation in order to find the speed.
k=162 N/m
x=7 cm=0.07m
m=0.135 kg
