- Why do leptons have integral charge while quarks have fractional charge?arrow_forwardThe quark compositions of the proton and neutron are, respectively, uud and udd, where u is an up quark (charge + 2/3 e) and d is a down quark (charge - 1/3 e). There are also antiup u (charge - 2/3 e) and antidown d (charge + 1/3 e) quarks. The combination of a quark and an antiquark is called a meson. The mesons known as pions have the composition π+ = ud- and π- = u-d. Suppose a proton collides with an antineutron. During such collisions, the various quarks and antiquarks annihilate whenever possible. When the remaining quarks combine to form a single particle, it is aA. Proton B.

- More than 60 years ago, future Nobel laureate Sheldon Glashow predicted that if an antineutrino — the antimatter answer to the nearly massless neutrino — collided with an electron, it could produce a cascade of other particles. The Glashow resonance phenomenon is hard to detect, in large part because the antineutrino needs about 1,000 times more energy than what's produced in the most powerful colliders on Earth. Let's compare this event to an ordinary baseball with a mass of 146 g. Please use three significant figures in your calculations. 1.What is the threshold antineutrino energy for the Glashow resonance in peta electronvolts (PeV)? 2.What is this threshold energy in units of joules? 3.Now consider a baseball with the same kinetic energy as that of the Glashow resonance. What speed in m/s would correspond to this energy? 4.What is this rate in units of inches/second? please help!!arrow_forwardIn the 19th century, the famous physicist Lord Kelvin estimated the age of Earth to be much less than the present estimate. What information that Kelvin did not have might have allowed him to avoid making his erroneous estimate?arrow_forwardThe rhinovirus, one cause of common cold and flu, has a diameter of 30 nm. How many of these particle could line up side by side on a line that is 1.0 inch long?arrow_forward
- Derive an approximate relationship between the energy of α decay and half-life using the following data. It may be useful to graph the log of t1/2 against Eα to find some straight-line relationship.arrow_forwardA state-of-the-art proton decay experiment is expected to detect 55% of the proton decays in a body of water. Assuming protons have a lifetime of 1031 years, how many m3 of water would you need in order to see 5 decays per month? (Assume a "month" is one-twelfth of a year.) Express your answer in scientific notation using two significant figures (e.g. 13680.3 would be expressed as 1.4*10^4).arrow_forward
