A particle cannot generally be localized to distances much smaller than its de Broglie wavelength. This fact can be taken to mea

The De broglie wavelength of a thermal neutron at room temperature 300K = 1.5 × A°

<h3>How is the De broglie wavelength of a thermal neutron at room temperature calculated?</h3>

Temperature, T = 300K

Momentum, p = mv

Therefore v = p/m

Energy, E= 1/2 m( p/m) ²

Boltzman Energy= 3/2 KT

3/2KT = 1/2 m(p/m)²

Therefore p = $\sqrt{3RTm}$

According to De broglie hypothesis, P = h ÷ λ

Therefore, λ = h ÷ $\sqrt{3RTm}$

= 6.6× $10^{-34}$ ÷ $\sqrt{3 \times 1.38 \times 10^{-23} \times 300 \times 1.6 \times 10^{-27} }$

= 0.15 × $10^{-9}$

Therefore the De broglie wavelength of a thermal neutron at room temperature 300K = 1.5 × A°

bulgar [2K]

The best answer is D.

Stress is a force that acts on rock to change its shape or volume. Because stress is a force, it adds energy to the rock, which is stored in the rock until either the rock breaks or changes shape.

There are three kinds of stress, namely shearing, tension and compression.

Shearing- force that pushes a mass of rock in two opposite directions and can cause rock to break and slip apart or change shape.

Tension - force that pulls on the crust, stretching rock so that it becomes thinner in the middle.

Compression - force that squeezes rock until it folds or breaks
