Answer:
A vibrating object produces sound waves. Energy needs to be transferred from the vibrating object to the ear through a medium..
Explanation:
Sound is transmitted through sound waves and waves transfer energy from the source of the sound to it environment in a pattern of disturbance and travels through a media. Sound waves carry energy parallel to the motion of the wave .
Since sound involve sound wave and energy as seen in the above explanation. We can not agree with Geneva given that 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 as a result of radio frequency signals that are leaking into our air causing them to bounce,reflect, enabling them to be heard in the human hearing range.
Answer:
If jobs are scarce in your locality, with layoffs occurring and home ownership put in jeopardy, values fall. Like a domino effect, fewer people can afford to buy a house. Owners lower their prices to compete in a diminished market.
Ocean tides are the result of differences in the gravitational force between
the sun and the Earth's near side and far side, and ditto for the moon.
In urban areas, there are more people, therefore not a lot of farmland. (that eliminates C) If city buildings don't allow flood waters to recede, that could be dangerous in many ways. (So A is still a reasonable answer) If most cities are built in flood zones, there should be some form of shelter if houses aren't safe. Pollutants and diseases being carried in water are already dangerous, but easier to spread with rapid flood waters that are sweeping everywhere. So your best answer would be either A or B.
