1. Compare the noise created by the object dropped from 20 cm above and the created after the pie tin repositioned.
2. Compare the noise created by the object dropped from 20 cm above the pie tin and the object dropped from 100 cm above the pie tin.
3. What is the GPE difference (∆U) of the object drop at two different distances from the pie tin?
4. What does the sound created by the object in situation number one indicate?
Answer
1.In this scenario, noise created by object fall from 20 cm above the ground to as compared to the pin reposition.
2.In this case, the noise created by object dropped from toorm height ia more as compared to sound made by object from 20 cm height.
3. GPE difference
"P=P_{100}-P_{20}\\\\=mg(100-20) *0.01\\\\=0.8mg"
4) Sound created by the object in situation 1 indicates that energy is constant. It can neither be created non be destroyed. PE of the object changed into sound energy.
