The answer is 20km because you go to yours friend's house and back then an extra 10km. 5+5+10=20km
The internal energy of an ideal gas is given by:
where
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
k=3 for monoatomic gases, k=5 for diatomic gases
In this problem, we have n=3.0 mol of a diatomic gas (k=5) at T=288 K. Substituting these numbers into the equation, we find the internal energy of the gas:
Explanation:
It is given that,
Initial state of electron,
Final state of electron,
The wavelength of the excited electron is given by :
Where
R is Rydberg's constant
or
Let f is the frequency of the observed photon. It is given by :
Hence, this is the required solution.
O_O how did I get here right now and 4 on the weekend.Does, and I will be in the morning. I have a duck, I will have to do with the help of the bottles. how may be able, I have to do it, and the processed food contain
Answer:
1.56 J
Explanation:
The potential energy only depends on the vertical height from the ground level.
We consider the ground level to have zero P.E.
So when it is 2 m above the ground level,
P.E. = mgh
= 0.078×10×2
= 1.56 J
