Yes, they look exactly like newborn babies
The two poles of magnets must have equal and opposite strength so they cannot be separated

Answer:
15.5 J
Explanation:
The total (mechanical) energy of an object is given by
E = K + U
where
K is the kinetic energy
U is the gravitational potential energy
The ball in the problem, when it left the hand, has:
K = 7.2 J (kinetic energy)
U = 8.3 J (potential energy)
So, its total mechanical energy is
E = 7.2 + 8.3 = 15.5 J
If field lines point
straight out from all sides of an object, then the statement that best
describes the object is that it is a south magnetic pole. The magnetic field lines have the same direction with the compass points.
This is known as a "Vaccum"
This is a common term when referring to Space.
A Vaccum is the space that contains no air or any other particles.
