Answer:
Explanation:
= Weight of bottle = 0.25 N
= Weight of water =
g = Acceleration due to gravity =
= Density of water =
Mass of water
Volume is given by
Volume of the bottle is .
This means that the alcohol will take the same amount of volume.
= Weight of alcohol =
Mass of alcohol
Density is given by
Density of alcohol is
Answer:
it enter through the ecosystem though the sun and later exists the ecosystem once the organisms in the food chain and the different trophic levels consume as much as they need in order to carry out their natural day-to-day process. Organisms release this energy in the form of heat back into the biosphere. hope this helps :)
The right answer is Negative (anion).
Anion is an ion that, having gained one or more electron (s), carries one or more negative electric charge (s), (since the number of negative charge (electrons) is greater than the number of charges positive (protons)): for example, the Cl- chloride ion is the chlorine atom that has gained an electron. Conversely, a cation contains fewer electrons than protons.
It is so called because during an electrolysis, this ion is attracted by the positive electrode called anode, in the same way that the poles of opposite charges of the magnets attract.
