The path of energy flow from the sun to the humpback whale is as follows:
- Sun---> Plankton ---> Small fishes ---> Humpback whale.
<h3>What is energy?</h3>
Energy is the ability to do work.
The primary source of energy on the earth is the sun.
The energy from the sun is used by producers to produce food on which other organisms depend on.
The energy from the sun gets to the humpback whale through producers such as plankton.
The path of energy flow from the sun to the humpback whale is as follows:
- Sun---> Plankton ---> Small fishes ---> Humpback whale.

Answer:The speed of light = frequency * wavelength
The speed of light is 3*10^8
So 3*10^8 / 4.8*10^13 = 6.25*10^-6 meters
Explanation:
As can be seen in the attached image, α-pyrone has a highly electrophilic carbon atom, since it is attached to two oxygen atoms that are electronegative and subtract electrical charge from the carbon, leaving it with a <u>positive partial charge</u>. By virtue of the above, <u>the bromine atoms, which have an important electron density that makes them good nucleophiles, will be attracted to the aforementioned carbon due to their positive charge</u>, thus favoring the substitution product to a greater extent than that of addition.
Answer:
Peropanamide participates in hydrogen bonding because it has the highest boiling point.
N, N-dimethyl formamide has the lowest boiling point due to the lack of hydrogen bonding
Explanation:
Compare N-methylacetamide with its amide isomers propanamide and N,N- dimethylformamide. Which do you predict has the highest boiling point? The lowest?
Peropanamide participates in hydrogen bonding because it has the highest boiling point.
N, N-dimethyl formamide has the lowest boiling point due to the lack of hydrogen bonding
Hi! the english version of the given question is "A helium balloon is inflated to the volume of 0.045 m3 at a temperature of 2 ° C. If the balloon is cooled to -12 ° C. What will its new volume be? Consider that the pressure does not vary". The answer is given in english.
Answer:
The new volume of balloon is .
Explanation:
Let's assume the helium gas inside the balloon behaves ideally.
The total number of moles of helium gas inside the balloon remains constant.
Applying combined gas law, we get:
Where:
are the initial and final pressure of the balloon respectively.
are the initial and final volume of the balloon respectively.
are the initial and final temperature in the kelvin scale respectively.
Given:
Substituting the above values, we get:
