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:
Partial pressure
Explanation:
the scientists is measuring different pressure, so it would be partial pressure. Hope that this helps you and have a great day :)
A piece of paper is thin, slighlty smooth, can be white and smells woody. 500 g of butter has a density of 0.911 g/ml and has a volume thus of 548.85 ml. Butter has a color yellow and smells fatty. A glass of milk has a white color, sour smell and taste and the milk occupies the volume of glass. Candle is waxy, can be long or short, can have colors of different varieties and is cylindrical.
