Answer:
The volume of the lungs at 5m deep is 4L
Explanation:
Hello!
We can solve this problem considering that the air inside de lungs behave as an ideal gas, and that the temperature is the same at sea leavel and 10 m below the surface, in this case:
P1 V1 = P2 V2 -- (1)
wher P and V stands for pressure and volume, and 1 and 2 for the intial (sea level) and final (5m below) states.
We know that:
P1 = 14.7 psi
V1 = 6 L
And if the pressure exerted by the water adds 14.7 psi to atmospheric pressure so 10 m below the surface, then at 5 m below it must add 14.7/2 psi, therefore:
P2 = (14.7/2) psi + atmospheric pressure = 7.35 psi + 14.7 psi
P2 = 22.05 psi
Solving equation (1) for V2:
V2 = V1 (P1/P2) = 6 L (14.7 psi / 22.05 psi ) = 6 *(2/3) = 4 L
The volume of the lungs at 5m deep is 4L
Answer:
emission of photon is of maximum wavelength when electron transition is from n = 8 to n = 5
Explanation:
Longest wavelength for the transition means the energy difference in two levels must me minimum
So here we know that the energy of electron in a given level is
now if z = 1 for hydrogen
then Energy of electron for n = 2
Energy of electron for n = 5
Energy of electron for n = 8
Now for least energy difference we can say
So emission of photon is of maximum wavelength when electron transition is from n = 8 to n = 5
Answer:
B: Greatest, A: Second greatest, C: Second geratest.
Explanation:
We can calculate the heat of fusion of a material (ΔHfus), which is the heat required to melt 1 kg of material, using the following expression.
ΔHfus = Q/m
where,
Material A
ΔHfus = 200 J/4 kg = 50 J/kg
Material B
ΔHfus = 300 J/5 kg = 60 J/kg
Material C
ΔHfus = 300 J/6 kg = 50 J/kg
Then, considering the heats of fusion,
B: Greatest, A: Second greatest, C: Second greatest.

The Sentences Nyah should use in her Explanation are :
B. An Ecosystem cannot Function without Decomposers.
D. Decomposers help to recycle nutrients in an Ecosystem.
<u>Because </u>:
✿ Producers provide food for Consumers.
✿ Ecosystems have many types of Decomposers like Bacteria & Fungi.
✿ Plants are not Examples of Decomposers.
