Neutron stars are so named because they are composed of neutrons and have a density the same as that of a nucleus. Part A Given that the nuclear density is 2.3 × 1017 kg/m³, find the radius of a neutron star whose mass is 0.58 that of the Sun. Express your answer using two significant figures.

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. (In data…

One of the end stages of stellar life is a neutron star, where matter collapses and electrons combine with protons to form neutrons. Some liken neutron stars to a single gigantic nucleus. Calculate the radius in meters of a neutron star with a mass 3.34 x 1030 kg, treating it as a giant nucleus. Consider the mass of a nucleon 1.675 x 10-27 kg. Your answer should be in the form of N x 104 years.

What is the Doppler shift of the gamma ray frequency to an outside observer(in Hz) ? Please answer it asap.

When a star has exhausted its hydrogen fuel, it may fuse other nuclear fuels. At temperatures above 1.0 x 10° K, helium fusion can occur. Write the equation for the following processes. (a) Two alpha particles fuse to produce a nucleus A and a gamma ray. What is nucleus A? (Enter the mass number in the first raised box, the atomic number in the second lower box, and the element, with charge if necessary, in the third box.) (b) Nucleus A absorbs an alpha particle to produce a nucleus "B" and a gamma ray. What is nucleus B? (Enter your answer using the same format as above.) (c) Find the total energy (Q) released in the reactions given in parts (a) and (b). Note: the mass of 4 = 8.005 305u. MeV

Let's say that gamma is a function of rho: y(p), and you suspect that gamma is proportional to rho raised to some power c. Yx p° You plot Ln(Y) on the vertical axis and Ln(P) on the horizontal axis, then apply a linear trendline resulting in the following equation y =3x + 1.0986 [ Select ] v is the proportionality constant that relates gamma and rho. rho is raised to the [Select] power.

At a neutrino detection facility deep underground in an abandoned salt mine, a research team is making calculationson how muchof two materials they will need in order to line the inside of adetection tank. The detection tank is a large sphere with an interior radius of 45.55 ft±0.500in. The two materials needed are gold with a density of 19.33 g/cm3and titanium with a density of 0.1630 lbs/in3. On the interior, the titanium layer will be applied first and the gold on top of that. The researchers look to purchaseenough titaniumto apply a layer that covers the entire interior of the sphere and has a thickness of 1.335 cm±0.500cm. Theprice of titaniumis $29.00per kg. On top of the titanium, the researches need to apply a layer of gold that is 700.0 microns thick and coversthe entire interior of the tank. The price of gold is $2,035per oz. What is the percent error in your calculation of gold needed if you ignored the change in volume to the tank created by applying the titanium layer…

If the gas is 4.49L were Radon instead of Hydrogen, what would it's mass be if it's density is 9.73g/l at STP? Is my calculatio/answer correct below: 9.73g/l x 4.49 = 43.6877 or rounded to 43.69g/l? Thank you
