I cant see the question's very well so ^
False because we dont know that because you didnt give us the problem'
Answer:
K1/K2=4
Step-by-step explanation:
The kinetic energy of a rotating sphere is given by:

The moment of inertia of a solid sphere is given by

The initial kinetic energy is therefore


The final kinetic energy is given by

Therefore the relation K1/K2 if R2 = 0.5R1

The text says nothing about the final angular velocity just the collapse of the collapse of the radius

Answer:
One solution (0, 3).
Step-by-step explanation:
As both expressions in x are equal to y:
3x + 3 = -2x + 3
3x + 2x = 3 - 3
5x = 0
x =0.
So y = 3(0) + 3 = 3.
