The respiratory system is made up of multiple organs, saying that the lungs is the only required organ is very wrong. While the lungs are probably the most important part of it, the organs that transfer the air are definitely necessary for everything to work.
The main organ that is needed for air to flow from the mouth to the lungs is the trachea, or the windpipe. This connects the back of the mouth to the lungs, without this, no air could get into the lungs, thus rendering them useless.
The slope of a position/time graph is the speed of the motion.
(The slope doesn't 'determine' the speed; it only displays it.)
The slope of a speed/time graph is the acceleration of the motion.
The types of fusion that occurs in stars are as follows:
- The proton-proton fusion - stars with temperatures less than 15 million Kelvin, minimum masses of 0.08 solar mass.
- The carbon cycle fusion - stars with core temperatures greater than 15 million Kelvin, minimum masses of 4.0 solar mass.
- The helium fusion - stars with core temperatures greater than 100 million Kelvin; minimum masses of 0.5 solar mass.
<h3>What is nuclear fusion?</h3>
Nuclear fusion is the process by which nucleus of small atoms combine together to produces atoms of larger nucleus.
The types of nuclear fusion that can occur in a star are;
- proton-proton fusion,
- helium fusion,
- the carbon cycle fusion.
The proton-proton fusion occur in stars which have core temperatures less than 15 million Kelvin having minimum masses of 0.08 solar mass.
The carbon cycle fusion occurs in stars with core temperatures greater than 15 million Kelvin having minimum masses of 4.0 solar mass.
The helium fusion occurs in stars with core temperatures greater than 100 million Kelvin having minimum masses of 0.5 solar mass.
In conclusion, fusion reactions occurring in the stars produce the energy released by stars.
