yes ,each piece will remain a magnet because the small pieces will cut into north and south
Answer:
I=1,2•10³ kg•m/s
Explanation:
v¹=3.5m/s
vf=5m/s
v=5-3.5=1.5m/s
I=p
I=mv=850•1.5=1275 kg•m/s=1,2•10³ kg•m/s
Answer:

Explanation:
For answer this we will use the paralell axis theorem:
I= 
Where
is the moment of inertia of the center of mass, M is the mass of the sphere and d is the distance between the center of mass and the axis for rotate, then:


Energy is able to be transferred from one into another
