Answer:
KE=2.3 x 10⁻¹⁹ J
Explanation:
Given that
λ = 544 nm
λ' = 485 nm
The kinetic energy KE given as
KE= E - Ф
Where
h= 6.626 x 10⁻³⁴
C=3 x 10⁸ m/s
Now by putting the values
KE=2.3 x 10⁻¹⁹ J
This is kinetic energy.
The speed of the winds corresponds to the tangential velocity of the tornado. Let's convert it into m/s:
The diameter of the tornado is , so its radius is
The angular velocity is related to the tangential velocity by:
And keeping in mind that 1 revolution corresponds to radians, we find the angular velocity in revolutions per second:
