Consider the fundamental process of pair production in which a particle and its antiparticle are created when a photon of high enough kinetic energy passes through the Coulomb field of a heavy nucleus. What exact conservation laws, if any, does this process violate? 1. Charge conservation... particles with charge are created out of nothing. 2. Baryon number conservation... matter is created out of nothing. 3. Lepton number conservation... matter is created out of nothing. 4. Energy conservation... particles with energy are created out of nothing. 5. Mass conservation... particles with mass are created from nothing. 6. It does not violate any known conservation law. correct answer is not conservation of energy.

Expert Solution

Fundamental process of pair production:

In pair production, Law of conservation of energy is not applicable.Because,here energy convert into mass

-Means energy having (photon)

-Means mass having(particle and antiparticle)

In this process,energy is collapsed(destroyed/impair) and equivalent amount of mass is generated(obtained).

Δm=E /c²

(Here,where Einstein’s mass energy equivalent)

So ,

A charge,baryon ,lepton and all other conservations of laws are applicable only in pair production.

Consider a widget factory that uses both labor and capital in its production process. The cost of each worker is $12 per hour. The cost of each machine is $20 per hour, regardless of the number of widgets produced. The following table shows the production and cost structure of the firm, where L is the number of workers, K is the number of machines, and TP is the total product, measured in the number of widgets produced per hour. L...

A manufacturing firm has adopted a new layout for its production process, which is intended to increase worker productivity. With the old layout, mean daily output was 200 units. A manager wants to test the null hypothesis that with the new layout, mean daily output is no greater than 200, against the alternative hypothesis that it is greater than 200. Assume that daily output levels are approximately normally distributed, with standard deviation 18 units. The manager decides they will take...

One of the many interesting fundamental particles in nature is the muon ?. This particle acts very much like a heavy electron and has a mass of 106MeV/c2, compared to the electron's mass of just 0.511MeV/c2. (Here we are using E=mc2 to obtain the mass in units of energy and the speed of light c). Unlike the electron, the muon has a finite lifetime, after which it decays into an electron and two very light neutrinos ( ?). We'll ignore...

Consider a particle which is constrained to move along the surface of the sphere of radius 5, centered at the origin. (a) If we write r(t) for the motion, write down the condition ‘constrained to move along the surface of the sphere of radius 5 centered at the origin’ in terms of r(t). (Hint. For later use, try to get rid of square roots.) (b) Explain why, for such a motion, we must have r 0 (t) ⊥ r(t). (Hint....

The Relative Importance of Factors of Fundamental Analysis Fundamental analysis is the process that aims to develop an understanding of the determinants of a company’s value based on the performance of the economy, the company’s industry and the business performance of the company itself. Fundamental analysis considers factors such as: the level and growth rate of the GDP, the evolution of interest rates, the government’s fiscal and monetary policies, the industry’s lifecycle, the financial metrics of competitors’ performance, the company’s...
