1. The mass of a neutron is 1.67 x 10-27 kg. Convert this to units of MeV/c². Calculate the velocity of neutrons required to perform neutron diffraction of a specific crystal, whose interatomic spacing is of the order 2A. What is the total kinetic energy for these neutrons? What is its relativistic energy? 2. From scattering experiments, it is found that the nuclear diameter is of the order of 10-15 m (1 fm). The energy of an electron in 8-decay experiment is of the order of a few MeV. Use these data and the uncertainty principle to show that the electron is not a constituent of the nucleus. 3. A free electron has wave function (x,t) =sin(kxwt). Determine the electron's de Broglie wavelength, momentum, kinetic energy and speed when k = 50 nm-¹

I am a little lost on how to re draw this graph. I appreciate the help. Thank you
where did you get the equation you used from?
REPLY AS SOON AS POSIBLE. please explain step by step A building has a square base of side 40.0 m and a height of 60.0 m. The base is aligned in the North-South direction (see figure). Starting from the ground at the Southwest corner, one mouse moves through the building ducts to the Northwest corner of the roof, while another mouse moves from the same origin to the center of the East side face (shaded in the drawing) Calculate: the red dot is the origin point. (A) The angle between the displacements of the two mice.(B) The direction angles of the second mouse displacement.(C) A unit vector that is perpendicular to the displacements of the mice.
