U is for Uranium. Natural uranium consists of 235U (percent abundance P₁ = 0.7300%, A₁ =
3.12 x 10-¹7 [s-¹]) and 233U (percent abundance P₂ = 99.27%, 2₂ = 4.92 × 10-¹8 [s-¹]).
Consider the time when Earth was formed 4.5 billion years ago.
Setup the time dependence of percent abundance of the two uranium isotopes. Use №₁ and N₂
as current particle count of the isotopes (use №₁,0 and N₂,0 for the initial particle count back
when Earth was formed)
Then, Compute for the initial percent abundance of each uranium isotopes when the Earth was
formed.

The photons that make up the cosmic microwave background were emitted about 380,000 years after the Big Bang. Today, 13.8
billion years after the Big Bang, the wavelengths of these photons have been stretched by a factor of about 1100 since they were
emitted because lengths in the expanding universe have increased by that same factor of about 1100.
Consider a cubical region of empty space in today's universe 1.00 m on a side, with a volume of 1.00 m³. What was the length

- (a) Estimate the mass of the luminous matter in the known universe, given there are 1011 galaxies, each containing 1011 stars of average mass 1.5 times that of our Sun. (b) How many protons (the most abundant nuclide) are there in this mates? (c) Estimate the total number of particles in the observable universe by multiplying the answer to (b) by two, since there is an electron for each proton, and then by 109, since there are far more particles (such as photons and neutrinos) in space than in luminous matter.arrow_forwardThe explosive energy of a ton of TNT is 4.184*109 Joules, according to Google. A megaton of TNT is a million times that. According to Wikipedia, the Tsar Bomba (Links to an external site.) was the most powerful thermonuclear weapon ever exploded, at 50 megatons of TNT. (For comparison, the explosive energy of WWII nuclear bombs was about 20 kilotons.) Suppose one kg of antimatter came into contact with matter. How would the explosive energy compare with the explosive energy of the Tsar Bomba? (c = 3 * 108 m/s) Group of answer choices 1.There is no way to compare the two. 2.The kg of antimatter would produce at least a hundred times more energy. 3.The Tsar Bomba produced at least a hundred times more energy than the kg of antimatter. 4. They would be approximately the same.arrow_forwardA magnetic field turns the velocity of a particle but does not change the speed, because the force is always perpendicular to the velocity. Particle accelerators (like CERN,) bubble chambers (to detect and characterize particles,) and mass spectrometers (to identify ions) all rely on this circular motion of charged particles in a magnetic field. In section 26.3, we learn that the radius of the circle made by a charged particle moving perpendicular to a magnetic field is T = mv qB (a) A particle is observed moving to the right when it enters a magnetic field. The magnetic field points into the page. When the particle enters the field, it moves in a clockwise circle. What is the sign of the charge? (b) Explain using physics language why the radius gets larger when the mass increases, and smaller when the charge or field increase. Discuss also why the radius tends to infinity (ie the path becomes a straight line) when the charge goes to zero. (c) At CERN, protons move almost the speed of…arrow_forward
- Vapor pressure of a pure component (Psat) can be computed from the correlation equations. Beattie et al.(1951) gives the following equation between 50.00 to 160.60 °C for neopentane: 1136.462 log10 pat = 3.901633 + 4.99118 10-4 T T (temperature in K and vapor pressure is in atmospheres). The critical temperature (Te) and critical pressure (Pc) of neopentane are 160.60°C and 31.57 atmospheres respectively. Using the information given above and the class notes, answer the questions #1. 1. The acentric factor w is used a characterization parameter in phase behavior calculations. Acentric factor is a measure of sphericity of a molecule. The definition of w is given below. psat @ =- log10 --1.0 prat is calculated at T/Tc= 0.7 Pc Here Pal is the vapor pressure of the component and, P. and T are critical properties of the component. Psat/P¢and T/Tc must be unitless (T and Tc must be in R or K). Calculate the acentric factor of neopentane (CSH12) using Antoine vapor pressure equation.

- Edwin Hubble observed that the light from very distant galaxies was redshifted and that the farther away a galaxy was, the greater its redshift. What does this say about very distant galaxies? When Hubble first estimated the Hubble constant, galaxy distances were still very uncertain, and he got a value for H of about 600 km/s per Mpc. What would this have implied about the age of the universe? What problems would this have presented for cosmologists?arrow_forwardThe "classical" radius of a neutron is about 0.81 fm (1 femtometer = 10-15 m).
