Answer:10,000
Explanation:When you look at the chart at 15 degrees, it is at 10,00. Hope this is right <3 Sorry if not :)
The volume of gas that exerts a pressure of 457 mmhg if exerted a pressure of 2.50 atm when its volume was 25.0ml is calculated as follows
by use of Bolyes law formula that is P1V1=P2V2
P1= 457mmhg
V1=?
P1 = 2.50 atm = 2.50 x760 = 1900mmhg
V2= 25,0 ml
V1 from the formula above = P2V2/P1
= 1900mm hg x25 ml/ 457 mm hg = 104 ml
Wavelength of the light is 2.9 × 10⁻⁷ m.
<u>Explanation:</u>
Planck - Einstein equation shows the relationship between the energy of a photon and its frequency, and they are directly proportional to each other and it is given by the equation as E = hν,
where E is the energy of the photon
h is the Planck's constant = 6.626 × 10⁻³⁴ J s
ν is the frequency
From the above equation, we can find the frequency by rearranging the equation as,
ν =
= ![$ \frac{6.8 \times 10^{-19}}{6.626\times10^{-34}} = 1.03\times10^{15} s^{-1}](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B6.8%20%5Ctimes%2010%5E%7B-19%7D%7D%7B6.626%5Ctimes10%5E%7B-34%7D%7D%20%3D%201.03%5Ctimes10%5E%7B15%7D%20s%5E%7B-1%7D)
Now the frequency and the wavelength are in inverse relationship with each other.
ν × λ = c
It can be rearranged to get λ as,
λ = c / ν
= ![$\frac{3\times 10^{8} ms^{-1}}{1.03\times10^{15}s^{-1}} = 2.9\times 10^{-7} m](https://tex.z-dn.net/?f=%24%5Cfrac%7B3%5Ctimes%2010%5E%7B8%7D%20ms%5E%7B-1%7D%7D%7B1.03%5Ctimes10%5E%7B15%7Ds%5E%7B-1%7D%7D%20%3D%202.9%5Ctimes%2010%5E%7B-7%7D%20m)
So wavelength is 2.9 × 10⁻⁷ m.
It would probably be K.E=1/2 m v2
