(a) The moment of inertia of the sign for rotation about the side of length h is 1.24 kgm².
(b) The kinetic energy of the sign when it is rotating about an axis is 141.37 J.
<h3>Moment of inertia of the triangular sign</h3>
The moment of inertia of the sign for rotation about the side of length h is calculated as follows;
I = 2 x ¹/₃M(b/2)²
I = 2 x ¹/₃Mb² x ¹/₄
I = ¹/₆Mb²
I = ¹/₆ x 4.4 x 1.3²
I = 1.24 kgm²
<h3>Rotational kinetic energy of the ball</h3>
K.E(rot) = ¹/₂Iω²
where;
- ω is angular speed = 2.4 rev/s = 2.4 x (2π rad)/s = 15.1 rad/s
K.E(rot) = ¹/₂(1.24)(15.1)²
K.E(rot) = 141.37 J

The carpal bones in the hands are an example of __________.
Answer: gliding joints
<span>A gliding joint means a freely moving joint in which the articulations allow only gliding motions</span>
<h2>The flux through each face is q/6ε₀ .</h2>
Explanation:
The charge q is placed at the center of the cube of side L
According to Gauss's law the flux through any closed surface is q/ε₀
here q is the charge enclosed .
In this case cube has the six faces . The flux through each face = q/6ε₀
In the second case The cube has the face with length L₁
The flux through each face = q/6ε₀
Thus flux through the cube does not depend upon the size of the cube .
