Consider a photon produced in the center of the sun. (A) How long this
Would it take photon to cross the sun and reach the surface if there was no absorption? (B)
Suppose the photon is continually absorbed and reissued so that its path to
surface can be considered as a random walk process. Assuming that reissues
occur instantaneously after each absorption, estimate the time needed for the photon to reach the
surface.

Expert Solution

(A) Time taken to reach surface with absorption of photon = 2.33 Sec

(B) Time taken by photon to reach surface with absorption taking place = 1 X 10⁵ years

how fast is the sun orbiting the center of the milky way? the revolution period is 230 million years. assume that the sun is 2/3 of the distance towards the edge of the milky way and the milky way is a galaxy of a typical size of a 100000 light years across. answer in Km/. speed of light is 300000 km/s

At this rate how long will the sun last? To estimate the age based on this you need to know: Percent of sun currently hydrogen – the sun is about 73% hydrogen by mass 6.5 x 1014 J/kg is released converting hydrogen to helium (You looked up the mass of the sun in kilogram You looked up the power of the sun in Watts (Joules/second) Using these four factors you can come up with the expected life of the sun)

How long does it take the Sun to melt a block of ice at 0∘C with a flat horizontal area 1.0 m2 and thickness 1.9 cm ? Assume that the Sun's rays make an angle of 32 ∘ with the vertical and that the emissivity of ice is 0.050. Express your answer to two significant figures and include the appropriate units.

Rotation: (a) The Sun orbits the center of the Milky Way at a speed of 220 km/s and a distance of 8 kpc. How much mass is interior to the Sun’s orbit, in units of the Sun’s mass? (b) A star three times the distance from the center of the Milky Way also orbits at 220 km/s. How much mass is interior to its orbit? To solve this, use your answer from part (a) and a ratio. (c) A star...

1. Imagine that the energy generation rate in the center of the Sun were suddenly to decrease. How would the size of the core, and hence density, change in response to changes you described in your answer to the previous question? 2.How would the density change in the previous question in turn affect the energy generation rate and hence the temperature? 3. Put your answers to the three previous questions together to explain how the Sun maintains a perfect structural...

Consider a high energy photon interacting in tissue. The photon first interacts via pair production before undergoing a Compton Interaction. The positron from pair production undergoes annihilation at the end of its life (no longer in-flight). One annihilation photon undergoes a Compton interaction and scatters at an angle of 100 degrees. Calculate the kinetic energy of the scattered photon.

Consider an infinitely long, straight coaxial cable consisting of a homogeneous cylindrical center conductor with radius a and a surrounding conductive tube (shield) with inner radius b. The space between the center conductor and the screen is filled with a dielectric with er (epsilon r) = 1. In the inner conductor, a direct current I is distributed evenly over the cross section. In the outer conductor there is a corresponding return current. On the surface of the inner conductor there...

Use the inverse square law to estimate how the brightness of the Sun would change if you moved from Earth at 1 AU to Saturn's location at 10 AU (i.e., give a fraction or percentage, not magnitude). Then, the brightest known star is R136a1 with an absolute magnitude of -12.5, explain why you cannot make a precise determination of its brightness as seen from Earth without more information
