Rubidium atoms are cooled to 0.20 μK in an atom trap.What is their de Broglie wavelength?

Physics
1 answer:
Ostrovityanka [42]3 years ago
5 0

Answer:

Thermal de Broglie Wavelength is 4.11×10-7 m

<u>Explanation: </u>

The thermal wavelength for a perfect quantum gas in any number of measurements and for a summed up connection between vitality and energy.

Thermal de Broglie Wavelength is generally the normal de Broglie wavelength of the gas particles in a perfect gas at the predetermined temperature

to find the thermal de Broglie Wavelength

we have the formula

      Λ = h / (2∙π∙m∙K∙T)^1/2  

Putting values in the formula where h is Planck constant, m is mass of the particles which is taken as an average mass per atom of rubidium, k is Boltzmann constant, and T is the thermodynamic temperature that is given above in the question.

Λ = (6.63×10⁻34 J∙s) / (2π(1.42×10⁻25 kg)(1.38×10⁻²³ J∙K⁻¹)(  

            0.20uK))

  = 4.11×10-7

Solution

It is the first colonial constitution and also the first written constitution in America. It was first applicable to the inhabitants and Residents of Windsor, Harteford and Wethersfield

The article V of the Fundamental Orders of Connecticut is subjected to the Courte of Election of the towns.

a water-balloon launcher with mass 4 kg fires a 0.5 kg balloon with a velocity of 3 m/s to the east. what is the recoil velocity
kotykmax [81]
I think we will use the law of conservation of linear momentum;
M1V1 = M2V2
M1 =  4 kg (mass of the water balloon launcher)
V1=?
M2= 0.5 kg ( mass of the balloon)
V2 = 3 m/s

Therefore; 4 V1 = 0.5 × 3
                   4V1= 1.5
                     V1= 1.5/4
                          = 0.375 m/s

If earth increase the distance from the sun, what will happen to the period of orbi t(the time it takes to complete one revoluti
Mandarinka [93]

The period of the orbit would increase as well

Explanation:

We can answer this question by applying Kepler's third law, which states that:

"The square of the orbital period of a planet around the Sun is proportional to the cube of the semi-major axis of its orbit"

Mathematically,

\frac{T^2}{a^3}=const.

Where

T is the orbital period

a is the semi-major axis of the orbit

In this problem, the question asks what happens if the distance of the Earth from the Sun increases. Increasing this distance means increasing the semi-major axis of the orbit, a: but as we saw from the previous equation, the orbital period of the Earth is proportional to a, therefore as a increases, T increases as well.

Therefore, the period of the orbit would increase.
