Explanation:
True
It is correct as the total rotational energy is the sum of transnational kinetic energy of each small piece of the object.
Consider a rigid body made of small particles each of mass dm have same angular velocity ω and the radius of the rotational path is r.
The velocity of each particle is v = r ω
So, the kinetic energy of each particle is
dK = 0.5 dm x v² = 0.5 x dm x r² x ω²
The total kinetic energy
K = 0.5 x I ω²
where, I is the moment of inertia
Answer:
There is no chemical combination of the substances in a mixture, so they retain their physical properties. There is the same composition throughout a homogeneous mixture. The structure of a heterogeneous mixture differs.

The answer is chicken nuggets

Because the effective charge of the nucleus increase from left to eight due to the increasing number of protons.
The greater charge pulls the electrons closer to the nucleus, decreasing the radius.
