The magnitude and direction of the angular momentum about the center of the disk is 0.996 kgm²/s.
<h3>Angular acceleration of the disk</h3>
The angular acceleration of the disk is determined by applying the principle of conservation of angular momentum as shown below;
Fr = Iα
α = Fr/I
Where;
- I is the moment of inertia of the solid disk
I = ¹/₂MR²
I = ¹/₂ x (0.5) x (0.08)²
I = 1.6 x 10⁻³ kgm²

<h3>Final angular velocity of the disk</h3>
ωf = ωi + αt
ωf = 45 + (1925 x 0.3)
ωf = 622.5 rad/s
<h3>Angular momentum</h3>
L = Iω
L = (1.6 x 10⁻³) x (622.5)
L = 0.996 kgm²/s
Thus, the magnitude and direction of the angular momentum about the center of the disk is 0.996 kgm²/s.
The complete question is below:
A uniform solid disk with radius 8 cm has mass 0.5 kg (moment of inertia I = (1/2)MR²). A constant force 14 N is applied as shown. At the instant shown, the amount of string that has wound off the disk is d = 22 cm, and the angular velocity of the disk is 45 radians/s into the page.

Answer:
Timing and energy are also factors in isomerism. Molecules are mobile entities, undergoing all sorts of rotational motions that change their shapes, and those motions require energy. Thus, some molecules can be the same on one timescale or set of energy conditions but different, or isomeric, on others.
Explanation:
Molecules are mobile entities, undergoing all sorts of rotational motions that change their shapes, and those motions require energy.
