Answer:
El aire es una mezcla de gases que forman la atmósfera, es por ello que se encuentra en todas partes. Sus componentes principales son el nitrógeno, oxígeno, dióxido de carbono, neón, helio, entre otros.
The answer would be 20% (B)
Answer:
Hi, There!
<em>Drinking energy drinks make people more hyper. What is the independent variable and the dependent variable?</em>
<em>The independent Vairable is the people drinking the energy drinks.</em>
<em>The Dependent variable is is the result which makes people more hyper</em>
Hope this Helps!
Answer and Explanation:
- <em>Computers ( The computers are very old and very slow, and we have to notice that almost everyone are using computers at the same time at the school, which makes it even harder for it to load up assignments. )</em>
- <em>The Rick Rolling ( Everyone keeps sending links to teachers and students saying that it is part of some assignment but then you have to listen to Rick Astley, they should really block these links. )</em>
- <em>The lockers ( The lockers are also very old and they are breaking down and rusting a lot from the moisture in the hallways. One of the lockers even broke down today!!! I hope they can fix this so no one else gets hit with a locker door. )</em>
<em>Hope this helps! ;)</em>
Answer:
The wavelength, λ, of a photon that has an energy of E = 3.92×10⁻¹⁹ J is 5.054*10⁻⁷ m
Explanation:
The wavelength is defined for every periodic wave, that is, for the type of wave that repeats itself with exactly the same shape every given interval of time. It is the distance between two points from which the wave repeats.
Radiation is the emission, propagation and transfer of energy in any medium in the form of electromagnetic waves or particles.
The energy carried by electromagnetic radiation travels by waves. This energy is transmitted grouped in small "quanta" of energy called photons. The energy of a photon is measured in Joules (J) and is
Being:
- E=3.92×10⁻¹⁹ J
- h= 6.626×10⁻³⁴ J⋅s (Planck's constant)
- c = 2.99×10⁸ m/s (the speed of light)
- wavelength=?
and replacing:
you get:
wavelength= 5.054*10⁻⁷ m
<u><em>The wavelength, λ, of a photon that has an energy of E = 3.92×10⁻¹⁹ J is 5.054*10⁻⁷ m</em></u>
