Answer:
greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range
Explanation:
Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
It should be at the very top since it has more space to fall which gives it more potential energy
As the source approaches you, the sound waves are compressed, so
the pitch of the sound is higher than what the source is actually emitting.
Then, after it passes you and begins moving away, the sound waves
are stretched, so the pitch of the sound is lower than what the source
is actually emitting.
Answer:
Increasing until terminal velocity is reached
Explanation:
Provided the scream is a constant pitch at the source, Doppler effect will make the pitch increase as the velocity of the source towards the listener increases.
