Answer:
Increase in Temperature (Global warming)
Explanation:
Incoming solar radiation is converted into heat energy and absorbed by the Earth's surface. The law of conservation of energy says that energy can neither be created nor destroyed but rather changes from one form to another. Now if more and more energy enters the Earth's surface and very little portion of it leaves the Earth's surface then a net disequilibrium in the energy balance will result in increased temperature because Earth is absorbing much more heat than it should!
One of the key factors of this unbalance is the pollution created by burning fossil fuels. Burning fossil fuels releases Carbon Dioxide CO2 and other pollutants.
Usually the leftover incoming solar radiation after being absorbed by the earth would escape back to the space but CO2 and other pollutants trap and absorb this radiation and thus, increases the Earth's temperature.
a decrease in the frequency of the sound wave.
Explanation:
When a sound source is moving away from an observer, the observer will hear a lower pitch due to a decrease in the frequency of the sound wave. This is known as the Doppler's effect.
- As the sound source moves closer to the observer, they hear a higher pitch in the reverse process.
- A sound wave transmits vibrational energy from the source to the hearer.
- A sound wave has frequency, amplitude, velocity and wavelength just like other wave types.
- The frequency of a wave is the number of waves that passes through a point at a time.
- This is related to the the wavelength of a wave.
- Waves of a high frequency are known to have short wavelengths and vice versa.
- To hear a low pitch, the source moves away and the wavelength between successive crests and troughs on a wave increases considerably.
