As we move above up from one trophic level to another in
an energy pyramid, what happens to the energy?
a. It decreases from one trophic level to another.
b. It remains the same for each trophic level.
c. It increases from one trophic level to another.
As we move above up from one trophic level to another in
an energy pyramid, the energy level decreases from one trophic level to
another. The answer is letter A.
The same amount of work being done over a longer period of time we must have power.
<span>a wave in a spring and a P wave are longitudinal waves. Both waves have compression and rarefaction
I hope this helps!

Interesting ...
gravity can be considered as *constant* acceleration, then you have:
h = v0*t + 1/2*g*t^2,
Final height is the same as the initial = 0
0 = 11*7 +1/2*g*7^2 ---> g = -11*7*2/7^2 = -22/7 m/s^2
Minus because it goes down, You can say g_planet = 22/7 m/s^2 ~ 3.14 m/s^2. Earth's one on its surface is about 9.81 m/s^2, so this planet has 3 times less gravity. It may be 1/3 the radius of the Earth, assuming same density. This is not asked! :)
Answer: The partial pressure of if the total pressure of the mixture is 3.9 atm is 0.975 atm
Explanation:
According to Raoult's law, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the vapor pressure of that component in the pure state.
where, x = mole fraction of nitrogen in solution = 0.25
= partial pressure of nitrogen = ?
= Total pressure = 3.9 atm
Putting in the values :
The partial pressure of is 0.975 atm
