Final answer:
Systems can be overclocked using software, which is false. The statements about observed frequency becoming infinite at the speed of sound and about the position vs time graph of an accelerating object being a straight line are both false. Waves of different frequencies can superimpose, which is true, and wave-particle duality does not apply to macroscopic objects, which is false.
Step-by-step explanation:
Understanding Systems and Frequencies in Physics
Regarding the statement whether systems can be overclocked using software, the answer is False. Systems can indeed be overclocked using specialized software to increase the clock speeds of components like CPUs and GPUs beyond their base operating frequencies. However, overclocking should be done with caution as it can lead to increased heat production and potential system instability.
Observed Frequency at the Speed of Sound. The claim that the observed frequency becomes infinite when the source is moving at the speed of sound is False. When a source moves at the speed of sound, a phenomenon called a sonic boom occurs, but the frequency does not become infinite.
