the answer is A i took a test
Answer:
3.83×10⁻¹⁹ J
Explanation:
The energy of a photon can be found using the formula: E=hc/λ
- h is Planck's Constant which is approximately 6.63×10⁻³⁴
- c is the speed of light which we'll round to 3.00×10⁸
- λ is the wavelength of the photon. You typed 5200 but that's not even within the visible light spectrum's wavelength range, so I'm going to assume you meant 520 nm; or 5.20×10⁻⁷ m.
Plugging all that info in should give approximately 3.83×10⁻¹⁹ Joules of energy.
(You could get slight variations depending on what you chose to round up or down or not at all.)
I have no idea what that is, but all of your answers right
The Newton’s law Nikolas would use to come up with this idea is the <span>Third law that states:
</span><span>When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
</span>
So, in this case, let's name the first Body
A which is the skateboard and the second body
B which is <span>the compressed carbon dioxide in a fire extinguisher. Then, as shown in the figure below, according to the Third law:
