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.
Bog soils are type of soils which are <span>poorly drained type that are found on top of peat ( topmost coal) and under a swamp environment. Although, these types are watery in nature, there is still a high percentage of organic matter in them like ordinary soils. Hence the answer is B. organic matter</span>
A.)Scientists look for fossils that could be common ancestors on the different
continents, showing that the common ancestor once existed on one or more
