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:
diameter / 2 = radius
3 / 2 = 1.5
radius x radius x height x pi = volume
1.5 x 1.5 x 6 = 13.5
We don't multiply by Pi because it is already included
Hope this helps
Step-by-step explanation:
Answer;
24 or 144.... figure it out bud
Step-by-step explanation:
Length x width x height=
Answer:
A= (3*X - 6
)/(X-4)
A=(3*2 - 6
)/(2-4)= -3+3
A=(3*4 - 6
)/(4-4) Unknown
Step-by-step explanation:
True, each number is getting doubled, both sides are proportionally staying the same.
