As per work energy theorem,
Work done by all forces = change in kinetic energy
If kinetic energy is different than your work input, then certainly other forces which are responsible for this discrepancy. These forces can be internal or external.
Answer:
no
Explanation:
bc electrolytes r like fuel
Answer:
The total initial volume of air in the tire is 800 cm³
Explanation:
Given;
volume of air in the bicycle pump, V₁ = 200 cm³
volume of the tire, V₂ = 800 cm³
The total initial volume of air in the tire is 800 cm³ and when the pump is pushed in, the total volume of air in the tire becomes 200 cm³. This occurs because the new air pumped into the tire through the bicycle pump compresses the air that was previously in the tire and raises the pressure of the tire that was initially flat.
From Boyle's law, a decrease in volume causes an increase in pressure.
The amount of energy lost at the transition between each trophic level of the pyramid of energy is about 90%.
There are a total of 4 trophic levels.
The producers which bare plants represent the first trophic level. Herbivores represent the second trophic level. Carnivores represent the third trophic level. Top carnivores represent the fourth trophic level.
The 10 % rule is followed by the energy flow in a food chain. It means that moving from one trophic level to another, only 10% of energy is transferred and the rest is lost in the atmosphere.
So the 90% percent energy is lost at the transition between each trophic level of the pyramid of energy.
