Answer:
D.autonomic nervous system
Potential energy = (mass) x (gravity) x (height) .
To raise the 20kg block 6 meters, you need to give it
(20 kg) x (9.8 m/s²) x (6 m) = 1,176 joules
of potential energy.
Your machine takes 2,000 joules of energy to give the block
the 1,176 joules that it takes.
Your machine is only (1176 / 2000) = 58.8% efficient .
The other 'missing' 824 joules of energy doesn't just disappear.
It heats the machine, and the air around it. The final result is
that when you use that machine to lift blocks, you have to use
even MORE energy, to blow cool air on the machine and prevent
it from overheating and breaking.
One major lab accident was of fire where gases were exposed to heat.
<u>Explanation:</u>
Accidents that occur in the laboratory which lead to some mishappening are known as the lab accidents. The reasons for such accidents may be many like fire, chemical spills, personal injuries and so on. To avoid all this, there should be proper check and focus while working in the lab.
One of the major lab accidents was of the fire when gas was exposed to heat. The chemical involved in this accident was the use of methane. The type of personal protective equipment worn at the time of accident was protective eye-wear and the lab coat and the lab gloves. To avoid such kind of accidents, people in lab should be very careful and it should be made sure that there are proper equipment in case of any mishap.
It would be nice to see the 4 stages titled to have a clue to what they could be. You see, chemical evolution is a myth, like Darwin's "warm little ponds." There are no naturalistic processes that have any power to accomplish the complex, diverse, extensive and highly non-entropic assembly of biochemical elements, molecules and assemblies into even the simplest life.
There is no primordial soup, panspermia is a distraction, none of the intractable issues for the origin of life.
Logically, the first step is collection of all elements, second, first level assembly of amino acids lipid membranes, proteins, third, higher level combination of biochemical molecules and generation of nucleotide coded DNA containing the processing code for generation and production of RNA, enzymes ribozymes and all other cellular functions, then fourth, the execution of all metabolism, nutrient collection, waste elimination and reproduction consistent with a living organism. Admittedly speculative since chemical evolution is a myth.
