No, I do not agree with her. In order for sounds to be heard, the sound wave produced by a vibrating object needs to travel from the vibrating object to the ear through a medium.

Answer from: Ryvers

The sound is a form of energy produced by vibration, hence it requires a vibrating medium or object to transmit within the space or vacuum. Therefore, the statement "the only thing that is needed for people to hear the sounds around us is a vibrating object" is correct.

Yes, we can agree with the statement. Sound is a form of energy which is produced by vibrations. The statement of Geneva, "the only thing that is needed for people to hear the sounds around us is a vibrating object" is correct in sense of concept of sound.

The role of vibrating object is that, it acts as a medium to transfer the vibrational energy from one point to another. For example- Atmosphere consists of various air and gas molecules, which act as a vibrating object. When source emits the sound, it strikes the air/gas molecules, causes vibration and the vibration is then transferred to another molecule.

In this way, successive transmissions make the sound waves to reach human ears to give the sensation of hearing.

Thus, we can conclude that to hear the sound, one need a vibrating object for the transmission of sound waves from one point to another.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

Answer from: Quest

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
