A blue giant star whose surface temperature is 23 kK radiates energy at the rate of $3.4 \times 10^{30} \mathrm{W}$. Estimate the average temperature on Pluto, treating the dwarf planet as a black body whose great distance from the Sun means that it receives energy from the Sun at the rate of only $0.876 \mathrm{W} / \mathrm{m}^{2}.$, The table below shows temperature versus time for $500 \mathrm{g}$ of water heated in a microwave oven. In high-mass stars, the cores begin to fuse helium into carbon and oxygen at a rapid rate. Two stars, both of which behave like ideal black bodies, radiate the same total energy per second. (a) What's the rate of heat conduction through the stove wall? Blue giants have a luminosity typically about 10,000 times that of the Sun and a surface temperature of 20,000 K or more. (d) Using the answer to part (a), estimate the rate at which photons leave the surface of the star. Strong UV continuum. (b) How much is the solar gain worth? Zero Kelvin equals -273 degrees Celsius. In a microwave, essentially all the microwave energy goes into the water-containing food in the oven. Giant and Supergiant Stars - Old, Large Stars RED GIANT A red giant is a relatively old star whose diameter is about 100 times bigger than it was originally, and had become cooler (the surface temperature is under 6,500 K). What is the hink-pink for blue green moray? Metallic lines become noticeable. (b) What's the rate of heat loss by radiation from the stove? As stars begin to die, they become giants and, Smaller stars (like our Sun) eventually become faint. The surface temperature of the star Rigel is $10^{4} \mathrm{K}$. Water's specific heat in the range from $0^{\circ} \mathrm{C}$ to $100^{\circ} \mathrm{C}$ is given very nearly by $c(T)=c_{0}+a T+b T^{2},$ where $c_{0}=4207.9 \mathrm{J} / \mathrm{kg} \cdot \mathrm{K}, a=-1.292 \mathrm{J} / \mathrm{kg} \cdot \mathrm{K}^{2},$ and $b=0.01330 \mathrm{J} / \mathrm{kg} \cdot \mathrm{K}^{3}.$ Use this expression to find the heat required to raise the temperature of $1.000 \mathrm{kg}$ of water from $0^{\circ} \mathrm{C}$ to $100^{\circ} \mathrm{C} .$ By what percentage does this differ from the result you would get using the value of $c$ in Table 16.1 over the entire temperature range? Who is the longest reigning WWE Champion of all time? So are is square p overhaul by tens e 10 saying what has t to a power for and t which the temperature has given us 23 killer Calvin, which is 23,000 Calvin. Okay, Over full by times E, which is one ties, five point six. Okay, so we know the power coming. Blue supergiants are supergiant stars (class I) of spectral type O. So the service areas off the stars a default, my arse work, okay. Ano ang Imahinasyong guhit na naghahati sa daigdig sa magkaibang araw? Assuming the sun to be a perfect blackbody sphere with a radius of $6.96 \times 10^{8} \mathrm{m},$ find its surface temperature (in kelvins). Assume the emissivity of the Sun is 0.986 .

I don't have an account. Assume that water's specific heat is independent of temperature (which is only approximately true; see Problem 73 ).$$\begin{array}{|l|c|c|c|c|c|c|c|}\hline \text { Time (s) } & 0 & 25 & 60 & 95 & 125 & 160 & 190 \\\hline \text { Temperature ('C) } & 12 & 20 & 39 & 53 & 64 & 83 & 93 \\\hline\end{array}$$. And times 23 1000. The surface of the Sun has a temperature of about 5800 $\mathrm{K}$ . Watts. (c) Use the results of (a) and (b) to find how much heat the stove loses by a combination of conduction and convection in the surrounding air. Singly ionized helium lines (H I) either in emission or absorption. Suppose a star with radius $8.50 \times 10^{8} \mathrm{m}$ has a peak wavelength of 685 $\mathrm{nm}$ in the spectrum of its emitted radiation. What's per meter? And t is the temperature Okay, so a can you go to P over E sigma Testy. There are many giant stars ranging from 30,000 K down to less How long will the footprints on the moon last? Go to Eastlake among has a test you for power for E is the facility was just curious. Ooh, p, which is 3.4 times sense of authority. Find the star's radius, assuming it bchaves like a blackbody. Okay, so if you're plugging all these values or get the radius R, it's just simply equal to square. In his case, Sigma is the Stefan Constant, which is 5.67 times 10 to a power in 88. They are extremely hot and bright, with surface temperatures of between 20,000 - 50,000 degrees Celsius. A star become a red giant when the core contracts, the temperature increases and the outer layers of the star begin to expand. Okay, so it seems area Can we go to four Pi r Square? You must be logged in to bookmark a video. Assume the star is a blackbody $(e=1)$ . Plot the data, determine a best-fit line, and use the slope of your line to determine the microwave power of this particular oven. View Winning Ticket. Above: the blue giant star in the centre is a main sequence O class star (the largest star shown in the Main Sequence Star picture) with a diameter about 18 times that of the Sun. Why? When did organ music become associated with baseball? And this will give us The radius is about four point 13 times 10 to the power when I meter. Calvin into the power for okay. By the end of this phase, the star can be 10 to 100 times it diameter. What is the time signature of the song Atin Cu Pung Singsing? The Study-to-Win Winning Ticket number has been announced! Its interior wall is at $650^{\circ} \mathrm{C}$, while the exterior is at $647^{\circ} \mathrm{C}$. The Sun has a radius of $6.96 \times 10^{5} \mathrm{km}$ and a blackbody temperature of $5780 \mathrm{K}$. The surface of the star is red, which according to Wien's Law, is a direct result of a low surface temperature. Go to your Tickets dashboard to see if you won! So the question was asking us to find a star's radius.
