When a body executes simple harmonic motion, its period is 1. the reciprocal of its speed. 2. proportional to its amplitude. 3.
2 answers:
Answer:
5. independent of its amplitude.
3. inversely proportional to its acceleration
Explanation:
The time period of oscillation is mathematically given as:
where:
length of the string through which the body oscillates.
acceleration due to gravity.
So, we can observe that it is independent of amplitude and depends on acceleration due to gravity and the length of the oscillating string.

Answer:
The moment of inertia I is
I = 2.205x10^-4 kg/m^2
Explanation:
Given mass m = 0.5 kg
And side lenght = 0.03 m
Moment of inertia I = mass x radius of rotation squared
I = mr^2
In this case, the radius of rotation is about an axis which is both normal (perpendicular) to and through the center of a face of the cube.
Calculating from the dimensions of the the box as shown in the image below, the radius of rotation r = 0.021 m
Therefore,
I = 0.5 x 0.021^2 = 2.205x10^-4 kg/m^2
