Answer:
Sound wave that have more energy are louder and have more frequency, amplitude and short wavelength
Explanation:
That bird's sound wave has more energy which has higher frequency of sound. Due to its higher frequency of sound, the amplitude is also higher. That sound which have higher frequency has short wavelength and those sounds which has lower frequency and pitch has long wavelength. So we can say that sound wave that have more energy are louder and have more frequency, amplitude and short wavelength whereas sound wave that have lower energy are less louder and have less frequency, amplitude and long wavelength
Answer:
Despite the availability of cleaner energy sources, most of the energy used to power American homes comes from the
burning of fossil fuels such as coal and oil. The burning of fossil fuels releases carbon dioxide into the air. Carbon dioxide
is a greenhouse gas that contributes to climate change.
Why do you think it's a challenge to reduce fossil fuel usage in homes in the United States? How could the use of fossil
fuels affect the biodiversity in neighborhoods and the surrounding ecosystems?
