Question

Question 21 5 pts A proton has a kinetic energy of 7.5 MeV. What is the speed of an alpha particle that has the same DeBroglie wavelength as the proton? The mass of the alpha particle is 6.65E-27 kg. O 9517 m/s O 9.53E6 m/s 1833 m/s 0 238E13 m/s O 0.747 m/s Question 22 5 pts How does the DeBroglie wavelength of the electron in the ground state of a hydrogen atom compare to the DeBroglie wavelength of the electron when it's in a 2p state? The DeBroglie wavelengths of the two electrons are equal The DeBroglie wavelength of the electron in the ground state is greater than that of the electron in a 2p state The DeBroglie wavelength of the electron in the ground state is less than that of the electron In a 2p state There is no way to compare the DeBroglie wavelengths of these two electrons.

Both questions plz, I will give a it a like.
