Answer:
Electrons are teeny tiny magnets. They have a north and a south pole, too, and spin around an axis. This spinning results in a very tiny but extremely significant magnetic field. Every electron has one of two possible orientations for its axis.In most materials, atoms are arranged in such a way that the magnetic orientation of one electron cancels out the orientation of another. Iron and other ferromagnetic substances, though, are different (ferrummeans iron in Latin). Their atomic makeup is such that smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. Below is an applet that shows you how these domains respond to an outside magnetic field.
Explanation:
First it will accelerate with acceleration a = 2.62 m/s^2
now the distance that it will move with this acceleration is
d1 = 0.5 * 2.62 * 12.8^2 = 214.6 m
so it will cover first 241.6 m during acceleration
now it will cover next distance with constant speed
so the distance covered is given as
d2 = v* t
d2 = 33.536 * 0.895*60 = 1800.9 m
after this it will comes to rest by constant deceleration which is given as by a = -11.2 m/s^2
so the distance it will cover is given by
d3 = (v^2 - vi^2)/(2a)
d3 = (0^2 - 33.536^2) / (2*-11.2)
d3 = 50.2 m
so the total distance that it move is given by
d = d1 + d2 + d3
d = 214.6 + 1800.9 + 50.2
d = 2065.7
so the total displacement is 2065.7 m

Answer:
24 Newtons
Explanation:
The force exerted in the middle cube needs to be enough to move the middle cube and the right cube with an acceleration of 2 m/s2.
The mass of those two cubes combined is 6 + 6 = 12 kg
So, using the following equation, we can find the force:
Force = mass * acceleration
Force = 12 * 2
Force = 24 Newtons
