An asteroid closely passes the Earth at a range of 17200mi and a relative speed of 7.8km/s.The diameter is estimated at 30mwith a specific gravity of 3. If this asteroid had impacted Earth, how much energy would have been released? Express this quantity in units of mega-tons (M ton) where a megaton is the energy released by one million metric tons of TNT explosive. A metric ton is 1000kgand the explosive energy density of TNT is 4184J/g.Hint: If the asteroid hits the Earth, its relative velocity becomes zero. Ignore any change in asteroid velocity due to gravitational acceleration or air resistance.
A neutron star is a cold, collapsed star with nuclear density. A particular neutron star has a mass twice that of our Sun with a radius of 12.0 km. (a) What would be the weight of a 100-kg astronaut on standing on its surface? (b) What does this tell us about landing on a neutron star?
Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?

We measure nuclear explosives in terms of kilotons of TNT (the bomb that destroyed Hiroshima in WWII was a 20 kiloton weapon.) 1 kiloton = 4.19 × 1012 Joules. How many Hiroshima-type bombs would you have to explode every second to equal the Sun's energy output? The purpose of this question is to illustrate that the most powerful (and destructive) things we (as a species) have created, there are things in the universe that are almost unimaginably more powerful.Number of Hiroshima-type bombs needed to equal 1 s of the Sun's energy output = _____ bombs/s
The temperature (T) of a planet (ignoring any other sources of heating) is solely a function of how far away the Sun is (d) and how bright it is (luminosity, L); planets are also reflective, so the light that they reflect (A) will not change their temperature: 1/4 L(1-A) T = 16σπα? o here is just a constant, like TT. 10. How much hotter is the Earth at perihelion than at aphelion? To answer this, solve for the ratio TT, where d, = r, (the perihelion distance) and d, = r, (the aphelion distance). You should have found that r, = 1.034rp. If you did not, use this new value and redo the previous problems.

In the Bohr model for hydrogen, the radius of the nth orbit can be shown to be »² times the radius of the first Bohr orbit = 0.05 nm (see Example 10.3). Similarly, the energy of an electron in the nth orbit is times its energy when in the - 1 orbit. What is the circumference of the n = 100 orbit? (This is the distance the electron has traveled after having revolved around the proton once.) For such large-n states, the orbital frequency is about equal to the frequency of the photon emitted in a transition from the nth level to an adjacent level with n + 1 or n - 1. Given this, find the frequency and corresponding period of the electron's orbit by computing the frequency associated with the transition 100 to n = 101. Using your values for the electron's orbital size (distance) and travel…

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 atmosphere 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…
