What role does Nitrogen play for all living organisms?
Answers
Answer 1
Answer:
It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
No you don't. After the sound is made, it has to travel to your ears before you can hear it.
The speed of sound in air is about 340 meters per second. That's about 760 miles per hour. That sounds awfully fast, but it means that it takes sound almost 5 seconds to cover 1 mile.
Sometimes when you're outside, you might see a neighbor down the street doing some carpentry outside his house, or you may see some workers putting a new roof on a house nearby. If you have this opportunity, watch their hammers carefully.
Light travels much much much much much faster than sound ... about 874 thousand times as fast as sound. So you see things just about as soon as they happen, but it takes the sound a while to reach you. If the distance is about 34 meters (about 110 feet) or more, then you can start to see the difference ... you'll see the hammer hit, and then you'll hear it. The farther the distance is, the longer the delay is.
The same thing happens at a baseball game when the batter connects. Firstyou see the ball hit the bat and fly away, and thenyou hear the CRACK !

Is the earth getting heavier
Answers
Yes. Earth gets bigger every year. This cumbersome everyday mass accumulation can be charged toward nearly 100 weights of stars penetrating the Earth’s environment per day.
Naturally yes, gravity plus the ever-increasing growing population of living organisms (human beings, animals, bugs, and etc.). Hope this helps!
The balance between incoming solar energy and out going energy radiated into space is called...
Answers
Based on the physics principle of conservation of energy, this radiation budget represents the accounting of the balance between incoming radiation, which is almost entirely solar radiation, and outgoing radiation, which is partly reflected solar radiation and partly radiation emitted from the Earth system, including the atmosphere.
How are intensity sound and energy related
Answers
sound is a form of energy in that it consists fluctuations of air pressure . The speed of the fluctuations is measured in cycles per second or Hertz (HZ)
Intensity is how large the fluctuations are, also known as amplitude and for the sound the unit is decibels of sonic pressure level (dB SPL)
