In a nuclear reaction, a Carbon-14 nucleus initially at rest emits a beta particle (an electron) with 156 keV of kinetic energy. The mass of a Carbon-14 nucleus is 14.000 u.

a. What is the speed of the beta particle? (in term of c)

b. What is the momentum of the beta particle?

c. What is the speed of the recoil nucleus after it emits the beta particle?

d. Choose the best option regarding the momentum of the recoil nucleus after it emits the beta particle:

- The momentum of the recoil nucleus is equal and opposite to that of the beta particle

- The momentum of the recoil nucleus is equal to that of the beta particle

- The momentum of the recoil nucleus is less than that of the beta particle

- The momentum of the recoil nucleus is less than that of the beta particle

The carbon isotope 14 C is used for carbon dating of archeological artifacts. 14 C ( mass 2.34×10^−26 kg ) decays by the process known as beta decay in which the nucleus emits an electron (the beta particle) and a subatomic particle called a neutrino. In one such decay, the electron and the neutrino are emitted at right angles to each other. The electron ( mass 9.11×10^−31 kg ) has a speed of 3.4×10^7 m/s and the neutrino has a...

A uranium-238 nucleus at rest undergoes radioactive decay, splitting into an alpha particle (helium nucleus) with mass 6.64×10-27 kg and a thorium nucleus with mass 3.89×10-25 kg. The measured kinetic energy of the alpha particle is 4.01×10-13 J. If after the decay, the alpha particle is observed to move in the positive x direction. After the decay, what direction did the thorium nucleus move? Complete the following statement with less than, greater than or equal to. After the decay, the...

A uranium-238 nucleus at rest undergoes radioactive decay, splitting into an alpha particle (helium nucleus) with mass 6.64×10-27 kg and a thorium nucleus with mass 3.89×10-25 kg. The measured kinetic energy of the alpha particle is 7.11×10-13 J. 1) After the decay, the kinetic energy of the thorium nucleus was _________ the kinetic energy of the alpha particle. (less than, greater than or equal to.)

Carbon-14 is unstable and decays to a differentnucleus(known as the daughter nucleusof the decay) along with an electron and an antineutrino (a particle with zero charge and virtually zero mass). The energy released in this decay (known as the Q-value) is found to be Q = 0.156476 MeV. Find the atomic number, the mass number, and the chemical symbol for the daughter nucleus of this decay. What is the mass of the daughter nucleus (in u)? [Hint: First find the...

A nitrogen atom of m1=14 u is moving with an initial kinetic energy Ki and strikes a stationary tungsten atom of m2=184 u. During the collision, some of the kinetic energy of the incident atom is used to ionize the stationary atom; an energy E is needed to eject one electron. The ejected electron has less than 0.0001 times the mass of the atoms, so it carries away a negligible momentum. After the collision, the two atoms stick together and...

1. For an object moving in uniform circular motion, does the centripetal force do work on the object? A. Yes, because work is force times distance and the object is moving from the force. B. No, because the force is always perpendicular to the object's displacement. C. No, because the displacement of the object is zero. D. Yes, because the object is moving. 2. An object is moving along a straight line with a speed of v when it hits...
