Question

The weakest of the four fundamental forces is Answer thegravitational force. the weak nuclearforce. the strongnuclear force. theelectromagnetic force. Fermium-253 has a half-life of 3.00 days. A sample of fermiumhas 7.37 × 107 nuclei. How long will it takefor there to be only 3.36 × 106 fermium nucleiin this sample? Answer 13.4days 58.6days 2.75days 15.7days 9.80days The weakest of the four fundamental forces is Answer thegravitational force. the weak nuclearforce. the strongnuclear force. theelectromagnetic force. Fermium-253 has a half-life of 3.00 days. A sample of fermiumhas 7.37 x 10^7 nuclei. How long will it takefor there to be only 3.36 x 10^6 fermium nucleiin this sample? Answer 13.4days 58.6days 2.75days 15.7days 9.80days Elementary particles that experience the weak nuclear forcebut not the strong force are called Answer mesons. baryons. leptons. hadrons. bosons. Uranium-238 decays into thorium-234 plus an alpha particle.How much energy is released in this process? 1 u = 931.494MeV/c^2. The relevant mass values are: He, 4.002603 u; Th, 234.043583 u; U, 238.050786 u. Answer 2.89MeV 4.28MeV 5.05MeV 3.76MeV 3.18MeV

Explanation / Answer

1. Gravity is the weakest of the four fundamentalforces. 2. 13.4 days. 3. Leptons respond only to the weak nuclear force.
