The energy of photon in kJ/mol is 329kJ/mol.
Wavelength of radiation is 370nm. The frequency of given wavelength is
ν = c / λ
ν = 3×10^8 / 370×10^-9
ν = 8.11 × 10^14 s^-1
Now the energy of photon is:
E = hν
E = 6.63×10^-34 J.s/photon × 8.11×10^14s^-1
E = 5.41× 10^-19 J/photon
To find in mole
E = 5.41× 10^-19 × 6.022×10^23
E = 3.29 ×10^ 5 J/mol
So, the energy of mole of photon is equal to 329 kJ/mol.

The answer is B) evaporation,condensation, precipitation, runoff/storage
Using the equation P = W/t to solve your problem .
Thus the answer is all of them use the same amount of power. 20 J.
Answer:
Explanation:
Knowing that the formula for average velocity is:
Being said that, we know that the person's displacement is zero because it returns to its starting point
That means
