    its:
    A Pressure Correct Answer Incorrect Answer
    B Amplitude Correct Answer Incorrect Answer
    C Acceleration Correct Answer Incorrect Answer
    D Moment of inertia Correct Answer Incorrect Answer

    Solution

    The spokes in a bicycle wheel increase its moment of inertia. A higher moment of inertia results in smoother bicycle motion. The moment of inertia quantifies a body's rotational inertia—the resistance it exhibits to changes in rotational speed when torque is applied. This property may be measured around internal or external axes, which may be fixed or movable.
