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 momentum of 8.7×10^−24 kg⋅m/s .

What is the recoil speed of the nucleus?

A neutron is an electrically neutral subatomic particle with a mass just slightly greater than that of a proton. A free neutron is radioactive and decays after a few minutes into other subatomic particles. In one experiment, a neutron at rest was observed to decay into a proton (mass 1.67××10−27−27 kgkg) and an electron (mass 9.11××10−31−31 kg). The proton and electron were shot out back-to-back. The proton speed was 5.0 ××1055 m/sm/s and the electron speed was 3.0 ××1077 m/sm/s....

Carbon-14 (14 6C) dating is a method for finding the age of an organic artifact from the quantity of 14 6C it contains. Carbon-14, an unstable isotope of carbon, follows a well-known sequence of decay processes. The decay constants of these processes have been well established, allowing researchers to determine the age of an artifact knowing both the original amount of 14 6C and the current amount. In the lab, it is relatively easy to measure the activity of a...

Carbon-14 is a radioactive isotope of carbon. It decays into Nitrogen-14 through beta decay, with a half-life of 5730 years. By comparing the amount of radioactive Carbon-14 with the amount of stable Carbon-12 (the most common isotope of carbon), we can determine the age of an object. a) How many protons and neutrons are in Carbon-14? Carbon-12? b) How many years will it take for an object to lose 87.5% of its Carbon-14? c) If 10000 years have passed, what...

Beryllium-8 is an unstable isotope and decays into two α particles, which are helium nuclei with mass 6.68×10−27kg. This decay process releases 1.5×10−14J of energy. For this problem, let's assume that the mass of the Beryllium-8 nucleus is just twice the mass of an α particle and that all the energy released in the decay becomes kinetic energy of the α particles. Part A If a Beryllium-8 nucleus is at rest when it decays, what is the speed of the  α...

The technique known as potassium-argon dating is used to date old lava flows. The potassium isotope 40K has a 1.28 billion year half-life and is naturally present at very low levels. 40K decays by two routes: 89% undergo beta-minus decay into 40Ca while 11% undergo electron capture to become 40Ar. Argon is a gas, and there is no argon in flowing lava because the gas escapes. Once the lava solidifies, any argon produced in the decay of 40K is trapped...
