By using the Plancks-Einstein equation, we can find the energy;
E = hf
where h is the plancks constant = 6.63 x 10⁻³⁴
f = frequency = 3.55 x 10¹⁷hz
E = (6.63 x 10⁻³⁴) x (3.55 x 10¹⁷)
E = 2.354 x 10⁻¹⁶J
Answer:
The (minimum) thickness of the oil slick is 325 nm.
Explanation:
Let the (minimum) thickness of the oil slick = 
Therefore:
2 = (
+
)*λ
/
(1)
similarly,
2=(
)*λ
/ (2)
Thus, equation 1 = equation 2
(+
*λ
= (
*λ
Where:
λ
λ
Therefore:
=650/390=5/3
This shows that,
=2
=1
Thus, using equation 2
=
<span>Answer: b. absorption of rainwater by soil
The word hydro in hydrosphere means water and the word geo in geosphere mean the earth soil. The system of hydrosphere will interact when the soil adsorption the rainwater. The other options are just interaction of hydrosphere without geosphere.</span>
The car should have less kinetic energy.
They are both going the same speed, but the truck is bigger and heavier. The more mass an object has, the more kinetic energy it has. There is more mass being moved, so it makes more kinetic energy. The car does not have as much mass, so it makes less kinetic energy compared to the truck.
Good luck with the rest of your test or quiz :)
I think it will be 800j because right absorb mean getting more
