period
When the amplitude of simple harmonic motion is doubled, the time period remains the same. The time period of simple harmonic motion only depends on the mass and spring constant of the system, not the amplitude.
When the amplitude of a wave is doubled, the energy in the wave increases by a factor of four. This is because the energy in a wave is directly proportional to the square of the amplitude. So, if the amplitude is doubled, the energy will increase by a factor of four.
If the amplitude of a sound wave is doubled, the intensity of the sound wave will increase by a factor of four. This is because intensity is proportional to the square of the amplitude of the wave.
If the amplitude of a wave is doubled while the frequency remains constant, the speed of the wave will not change. The speed of a wave is determined by the medium through which it is traveling, not by its amplitude or frequency.
If the speed of a moving object is doubled, the object's kinetic energy must also double, as kinetic energy is directly proportional to the square of the object's speed.

That if the original amplitude was A then it is now 2*A.
If the amplitude of a sound wave is doubled, the intensity of the sound wave will increase by a factor of four. This is because intensity is proportional to the square of the amplitude of the wave.

The pendulum swings twice as far.
If the speed of a moving object is doubled, the object's kinetic energy must also double, as kinetic energy is directly proportional to the square of the object's speed.
When the amplitude of a vibration is doubled, the loudness of a sound will increase by 6 decibels. This is because the decibel scale is logarithmic, and a doubling of amplitude corresponds to an increase of 6 dB. This means that the sound will be perceived as approximately twice as loud to the human ear.
In Frequency Modulation (FM), if the modulation frequency is doubled, the modulation index does not necessarily double; it depends on the amplitude of the modulating signal. In Amplitude Modulation (AM), the modulation index is defined as the ratio of the peak amplitude of the modulating signal to the carrier amplitude, so it remains unchanged with varying modulation frequency. For Phase Modulation (PM), similar to FM, the modulation index is influenced by the amplitude of the modulating signal and does not inherently double with the modulation frequency. Thus, modulation frequency and modulation index are not directly linked in this way for FM, PM, or AM.
Salt
If the spring's length is doubled, the spring constant is unchanged, and the velocity will remain the same in simple harmonic motion with a spring. The period of oscillation will change, as it is affected by the spring constant and mass of the object.
