The surface of the Sun has a temperature of 5500 ∘C. Treat the sun as a perfect blackbody with an emissivity of 1.0 and a radius of 7.0*10^8 m. Given; the temperature of space is 3.0K and the power that it takes for the sun to radiate into space is 3.9 * 10^26 W. The solar constant is the number of watts of sunlight power falling on a square meter of the Earth's upper atmosphere. Calculate the solar constant given...

The surface of the sun has a temperature of about 5800K and consists largely of hydrogen atoms. Find the rms speed of a hydrogen atom at this temperature. (The mass of a single hydrogen atom is 1.67×10−27kg.) The escape speed for a particle to leave the gravitational influence of the sun is given by (2GM/R)1/2, where M is the sun's mass, R its radius, and G the gravitational constant. The sun`s mass is M=1.99×1030kg, its radius R=6.96×108mand G=6.673×10−11N⋅m2/kg2. Calculate the...
The surface of the Sun is approximately 5, 500 K, and the temperature of the Earth's surface is approximately 291 K. What entropy change occurs when 6,000 J of energy is transferred by heat from the Sun to the Earth?
The Sun shines with a blackbody temperature of 5780 K and a total power output of 3.8 x 1026 w. The Sun has been doing this for 4.5 x 10 yr, during which time the surface temperature has increased by a few percent and the luminosity by 20%, ie. they have remained roughly constant. (a) (5 marks) Use the heat-flow formula for entropy change to calculate the total entropy in all the sunlight the Sun has ever emitted. (b) (3...
A beam of helium atoms, originating from a supersonic nozzle maintained at a temperature 400 K, strike a closely packed nickel surface at normal incidence. The kinetic energy of the helium atoms is equal to 3 KĖTnozzle where ke is the Boltzmann constant. The molar mass of helium is 4.003 x 10-3 kg mor? Given that the spacing between the rows of nickel atoms is 240 pm calculate the angle to the perpendicular at which the fourth order diffraction peaks...
