Answer:
magnitude of the pressure on the sail in the vicinity of Earth’s Orbit=
Explanation:
The momentum of a photon is:
p = E/c
E = the photon energy
c = the speed of light.
take the time derivative (gives the force)
F = dp/dt = (dE/dt)/c
F = 2(dE/dt)/c (is doubled for complete reflection of the light)
Intensity has the units of energy per unit time per unit area
= I
then,
Force/unit area = 2I/c
magnitude of the pressure on the sail in the vicinity of Earth’s Orbit=
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.

To solve this problem we will apply the ideal gas equations for which the product of pressure and volume is defined, as the equivalent between the ideal gas constant by the amount of matter and the temperature, mathematically this equation is described as
Here,
P = Pressure
V = Volume
R = Ideal gas Constant
T = Temperature
n = Number of molecules
The pressure is in atmospheres, and considering the units of the other values we have finally that,
Replacing,
Multiplying the number of moles by Avogadro's number we have,
Therefore the number of ozone molecules in the Earth's ozone layer are
Answer:
If the Lego building is shaken side to side, it will withstand up to 60 seconds because front to back will cause the top of the building to collapse.
