Beta decay is the process by which a neutron decays to a proton (which typically stays in the original nucleus) an electron, and neutrino (if we’re being technical, this is an electron-antineutrino). This is one of the processes by which a heavy nucleus with many neutrons can move back towards stability. Carbon-14 decays to Nitrogen-14 via this process. The electron and neutrino are emitted in opposite directions. The electron momentum is 1.1 x 10-22 kg m/s and the neutrino has a momentum of 5.4 x 10-23 kg m/s. a. What is the linear momentum of the nucleus after the decay? Take the electron direction to be in the positive x-direction.
b. If the mass of the residual nucleus is 2.34 x 10-26 kg, then what is the kinetic energy (in Joules) of the recoiling nucleus? In real life, the recoiling nucleus and the electron would be measured, allowing one to infer the momentum of the neutrino (this incidentally was the reason the existence of the neutrino was proposed).

Anne applies a force on a toy car and makes it move forward. what can be said about the forces acting on the toy car at the moment anne applies the force?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
