Answer:
a) p = 1.10 * 10⁻²⁷ kg·m/s
b) p = 9.46 * 10⁻²⁴ kg·m/s
c) p = 3.31 * 10⁻³⁶ kg·m/s
Explanation:
To solve this problem we use the <em>de Broglie's equation, </em>which describes the wavelenght of a photon with its momentum:
λ=h/p
Where λ is the wavelength, h is Planck's constant (6.626 * 10⁻³⁴ J·s), and p is the linear momentum of the photon.
Rearrange the equation in order to solve for p:
p=h/λ
And now we proceed to calculate, <u>keeping in mind the SI units</u>:
a) 600 nm= 600 * 10⁻⁹ m
p=(6.626 * 10⁻³⁴ J·s) / (600*10⁻⁹m) = 1.10 * 10⁻²⁷ kg·m/s
b) 70 pm= 70 * 10⁻¹² m
p=(6.626 * 10⁻³⁴ J·s) / (70*10⁻¹²m) = 9.46 * 10⁻²⁴ kg·m/s
c) 200 m
p=(6.626 * 10⁻³⁴ J·s) / (200m) = 3.31 * 10⁻³⁶ kg·m/s
Answer:
1.005 cm³
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 0.650 cm³
V₂ = ?
P₁ = 1.54 atm
P₂ = 1.01 atm
T₁ = 12°C
T₂ = 16 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (12 + 273.15) K = 285.15 K
T₂ = (16 + 273.15) K = 289.15 K
Using above equation as:
Solving for V₂ , we get:
<u>V₂ = 1.005 cm³</u>
Answer:
false
Explanation:
the answer is false because there is minerals in our water, ect.
