We are given with
<span>m1 = 9.3 kg
R = 0.22 m
ω = 31 rad/s
m2 = 3.9 kg
L = 2R = 0.44 m
The angular momentum is determined using the formula
L = I w
where I is the moment of inertia
For a solid disk
I = (1/4) MR^2
For a rectangular rod
I = (1/12) ML^2
The rotational energy has the formula
E = (1/2) I w^2
Substitute the given values for getting the answers

3429 paperclips because a football field is 120 yards and 120 yards converted to centimeters is 10972.8cm so 10972.8cm divided by 3.2 is 3429.
The Kinetic energy would be 1/2IL².
<h3>What is
Rotational Kinetic energy ?</h3>
- Rotational energy also known as angular kinetic energy is defined as: The kinetic energy due to the rotation of an object and is part of its total kinetic energy. Rotational kinetic energy is directly proportional to the rotational inertia and the square of the magnitude of the angular velocity.
As we know linear Kinetic energy = 1/2mv²
where m= mass and v= velocity.
Similarly rotational kinetic energy is given by = 1/2IL²
where I- moment of inertia and L=angular momentum.

Explanation:
what's the actual question
Answer: Valence electrons
Valence electrons are those that are in the outermost or superficial layer of the atom, which means they have the highest energy compared to those of the inner layers.
Because of their position, it is easier for these electrons to interact with other atoms of their own element as well as different elements. This is done through the process of forming bonds when being attracted by other atoms.
