- Calculate the average density of the following astronomical body: Pluto.High energy cosmic rays from space hit the nitrogen in the atmosphereand convert it from nitrogen (N14) into carbon (C14). This produces a steadyconcentration of C14 in the atmosphere once the decay rate of the C14 back intoN14 matches the conversion rate from the cosmic ray flux (which is assumedto be constant for reasons you can ask me about if you want) a) What kind of radiation (what kind of particle) does the C14 emit when it decays? Tellme how you know?b) The concentration of C14 in plants (and animals) comes into equilibrium with the at-mosphere because living things use the ambient carbon to make their cellular structures.However, once a plant dies, it no longer consumes C14. The C14 starts to decay away—allowing us to calculate when the plant died because the C14/C12 ratio doesn’t match theatmosphere. If the half life of C14 is 5000 years, what is the age of a piece of charcoal froma site from the Clovis peoples of North America if the concentration of C14 is 15% of…Venus' exosphere has a temperature of about 404 K. What is the thermal speed of hydrogen (in km/s) in Venus' exosphere? The mass of a hydrogen atom is 1.67 x 10-27 kg and Boltzmann's constant is k = 1.38 × 10-23 Joule/Kelvin.
- #16- Please solve this on a piece of paper so it will be easier to understand. - Please provide a step-by-step explanation as well.Evidence exists that Mars may have had oceans 0.500 km deep in its early history. We don't know what the atmospheric pressure on Mars was back then, but some studies suggest it may have been as high as 50,000 Pa. What would have been the highest pressure at the bottom of these oceans? Density of water is 1000 kg/m³, gmars = 3.71 m/s².
- In 1999, scientists discovered a new class of black holes with masses 100 to 10,000 times the mass of our sun that occupy less space than our moon. Suppose that one of these black holes has a mass of 1x10^3 suns and a radius equal to one-half the radius of our moon. What is the density of the black hole in g/cm^3? The radius of our sun is 7.0x10^5 km, and it has an average density of 1.4x10^3 kg/m^3. The diameter of the moon is 2.16x10^3 miles.Why do we think that planets in our Solar System were not formed out of the gaseous disk by direct gravitational collapse? Planets are formed in disks. Disks rotate too fast to collapse gravitationally to form planets. In disks that are not massive enough, tidal gravity of the central star prevents the disk gas from collapsing. The material in the disk orbits close to the star. This makes the disk too hot, and pressure support prevented the disk from gravitational collapse. The gravity of the forming planets was not enough to accrete gas.You have negotiated with the Omicronians for a base on the planet Omicron Persei 7. The architects working with you to plan the base need to know the acceleration of a freely falling object at the surface of the planet in order to adequately design the structures. The Omicronians have told you that the value is gOP7=7.29 flurg/grom^2, but your architects use the units meters/second^2, and from your previous experience you know that both the Omicronians and your architects are terrible at unit conversion. Thus, it's up to you to do the unit conversion. Fortunately, you know the unit equality relationships: 5.24flurg=1meter and 1grom=0.493second. What is the value of gOP7 in the units your architects will use, in meter per second squared?
- a. Calculate the surface temperature of Pluto and Charon at perihelion, assuming both bodies are rapid rotators and in equilibrium with the solar radiation field. b. Calculate the escape velocity from Pluto and Charon, and compare these numbers with the velocity of N2, CH4, and H2O molecules. c. Given your answers in (a) and (b), explain qualitatively the differences in surface ice coverage for Pluto and Charon.c) Derive the Schwarzschild criterion for the onset of convection in an ideal gas, namely d ln T d ln P 7-1 Y Explain all steps in your derivation, and justify any assumptions that you make. d) In a region of convective instability near the surface of a solar-type star of total mass M, the temperature and pressure are related approximately by the expression P KT5/2. Show that the temperature gradient for an ideal gas in hydrostatic = equilibrium in this convection zone is given by dT dr 2Gm(r)μ 5Rr² Further, assuming that the mass in the convection zone is small compared to M, show that at a depth h measured from the top of the convection zone, the temperature is approximately given by T = Ts + 2GMμ -h₂ 5RR² when his small compared to R, and Ts is the temperature at the top of the convection zone.
