Final answer:

To find the speed of a proton given its de Broglie wavelength of 129 pm, you can use the de Broglie wavelength formula and the momentum-speed relationship.


Explanation:

The de Broglie wavelength formula is λ = h / p, where λ is the wavelength, h is Planck's constant, and p is the momentum of the particle. Given that the de Broglie wavelength of a proton in a linear accelerator is 129 pm, we can find the speed of the proton by using the formula v = p / m, where v is the speed, p is the momentum, and m is the mass of the proton.
