Answer:
3 and 1/6
Step-by-step explanation:
Yes it is greater than -1/2
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:
8 1/2
Step-by-step explanation:
They are on opiate sids of zero so add the absolute values together to get 1/2
Answer: 4/5
Step-by-step explanation: For a line to be parallel to another line there must be two conditions true.
Condition 1: Both lines must have the same slope (i.e the same x in the form y = mx + b)
Condition 2: Both lines must have different y-intercepts (i.e different b in the form y = mx + b)
Thus, if you are looking for the slope of the line parallel to y = 4/5x - 3, we can look at condition 1, and see that the slope should also be 4/5 for the other line.
