About 33 percent of the total results from e-e collisions with the rest from e-z collisions mainly e-p and e-alpha.

. Luminosity is an absolute measure of radiant power. Wavelengthfrequency the flux is determined at. You are tasked with building a solar power plant in the Arizona desert using solar panels with 10 efficiency.

How many tons of matter in the sun is annihilated every second to produce its luminosity of 39 x 10 33 ergs per second. To the equation E mc2 then estimate the Main Sequence lifetime. The luminosity of the Sun is 41033 ergs and its radius is 71010 cm.

Luminosity of the sun- 38461026 watts. The luminosity of the Sun is 4 1033 erg s-1 and its distance to the Earth is 15 1013 cm. The suns luminosity is about 38 x 1026 Joules a second.

That is its value is independent of. Eddington 1920s suggested that the sun might generate energy by fusing hydrogen into helium. In terms of mass you can think of the total energy output as about 4000000 tons every second.

Where Does the Sun Get Its Energy. He occurs at an. The Suns absolute B magnitude is MB 548.

To understand how fusion occurs we must know more about subatomic particles and the interactions between them. From Einsteins famous equation E mc2 and using c 3 x 1010 centimeterssec the Suns luminosity is equal to a loss of mass from the fusion cycle of about 2 x 1012 gramssecond. To measure the brightness or luminosity also called as radiant power of a star astronomers use the Suns own level of luminosity as their point of comparison.

Or 38461033 ergs per. Try and define that. How large an area km2 must your solar panels cover to match the power output of a large nuclear powerplant about a Gigawatt.

Life time is related to source of energy life time energy available luminosity Gravitational Contraction. The solar luminosity L is a unit of radiant flux conventionally used by astronomers to measure the luminosity of stars galaxies and other celestial objects in terms of the output of the Sun. Energy per fusion is small 4x10-5 ergs and the luminosity of the sun is 4x10 33 ergssecond but there are lots of atoms in the sun.

39 x 10 33 30 x 10 20 13 x 1013 grams per second or 13 x 1013106 13 x 105 metric tons of mass. Usually the total energy given off by an object per second. One nominal solar luminosity is defined by the International Astronomical Union to be 38281026 W.

Usually measured in ergs. LSirius-B 000071 x 4900 km x 10 5 cmkm 2 27400 4 95 x 10 31 ergssec LSirius-B 95 x 10 31 ergssec 36 x 10 33 ergssec 0026 Lsun. Luminosity in astronomy the amount of light emitted by an object in a unit of time.

This does not include the solar neutrino luminosity which would add 0023 L or 881024 W. Solar luminosity is the total power output of the Sun radiated to space. One metric ton 10 6 grams.

Ergss it is determined for whatever. Assume the Suns core 10 of the total. The luminosity of the Sun is 200 trillion trillion watts or 2 x 1033 ergs per second.

However the Suns luminosity does not always stay the same. The total luminosity Lg in gravitons is about 79 x 10 to the 14th ergss close to an earlier estimate by Weinberg 1965 1972. An erg is about the energy of.

6 The Sun radiates a total luminosity of about 4 x 1026 Watts 4 x 1033 ergss into space. Imagine a supernova explodes at the center of the Solar System. Luminosity - energy per second.

What is the flux of sunlight on the Earth in units of ergs-ls-cm-2. The luminosity of the Sun is 41033 ergss and its distance to the Earth is 15 1013 cm. Solar irradiance in contrast is the total power per unit area at a distance of 1 AU see solar constant.

2 4 L 4 pi R sigma T. One solar luminosity unit therefore is equal to about 38391026 W or 38391033 ergs or the Suns commonly accepted luminosity. Suns Luminosity 3828 x 10³³ ergs.

If we think of this as a miniature internal sun then the total luminosity of this internal surface is. Magnitude The magnitude is the standard unit for measuring the. We are located at about 1013cm from the Sun.

Suns Surface Area 609421 x 10²² square centimeters. The luminosity of the Sun is 3846 10 26 watts or 3846 10 33 ergs per second. You are tasked with building a solar power plant in the Arizona desert using solar panels with 10 efficiency.

The Suns radius is about 7 x 108 m 7 x 1010 cm. The luminosity of an object measured over all wavelengths. How large an area km2 must your solar panels cover to match the power output of a large nuclear powerplant about a GigaWatt.

The mass of the sun is 198 x 10 33 grams.

Efficiency of 07 and that mass is converted into energy according. Where sigma 56 x 10-5 so that L 4 x 3141 x 2500 x 1052 x 56 x 10-5 x 45004 or 18 x 1028 ergssec. 5 When it first ignites a rough estimate for the luminosity of a supernova is 1051ergssec about 1018or a billion billion times more luminous than the Sun.
