Students have asked these similar questions
1. If a proton is moving at very high speed, so that its kinetic energy is much greater
than its rest energy (mc²), can it then decay via p →n + n+?
2. What would an “antiatom," made up of the antiparticles to the constituents of normal
atoms, consist of? What might happen if antimatter, made of such antiatoms, came
in contact with our normal world of matter?
Why does primordial nuclesythesis end about 3 minutes after the Big Bang ?
select one :
a. The number densities of photons is too large at this time and the photons induce fission , stopping nuclei formation
b. The universe is tooo hot at t=3 minutes
c. The number densities of neutrons and protons and other nuclei are too small at this time and fusion fades out .
d. Deuterium has a lifetime of 3 minutes , so after this time no more deuterium survives as it decays away ?
this question just got rejected due to complexity, and it already has answer on chegg. I guess I won't be staying here for long..

- What do you mean by quarks?arrow_forwardhello, how we solve this problem?arrow_forwardIs it possible that some parts of the universe contain antimatter whose atoms have nuclei made of antiprotons and antineutrons, surrounded by positrons? How could we detect this condition without actually going there? Can we detect these antiatoms by identifying the light they emit as composed of antiphotons? Explain. What problems might arise if we actually did go there?arrow_forward
- Explain what is meant by the term cosmological redshift, and contrast it with the Doppler shift that is observed when a luminous object recedes from an observer. From the defi- nition of redshift in terms of the observed and emitted wavelengths of photons, obtain an expression that relates redshift to the expansion factor of the Universe. Hence calculate the expansion factor of the Universe while a photon travels from a galaxy with redshift z = 1.arrow_forwardUse Wien’s law to answer the following questions: (a) The cosmic background radiation peaks in intensity at a wavelength of 1.1 mm. To what temperature does this correspond? (b) About 379 000 y after the big bang, the universe became transparent to electromagnetic radiation. Its temperature then was 2970 K.What was the wavelength at which the background radiation was then most intense?arrow_forwardI asked the following question and was given the attached solution: Suppose that the universe were full of spherical objects, each of mass m and radius r . If the objects were distributed uniformly throughout the universe, what number density (#/m3) of spherical objects would be required to make the density equal to the critical density of our Universe? Values: m = 4 kg r = 0.0407 m Answer must be in scientific notation and include zero decimal places (1 sig fig --- e.g., 1234 should be written as 1*10^3) I don't follow the work and I got the wrong answer, so please help and show your work as I do not follow along easily thanksarrow_forward
