Apparently the Sun loses 4200 000 000 kilograms of mass every second, how do you measure something like that?

Answer 1

Earth's orbital velocity changes from the distance of the sun and this with Keppler's law and Newton's law weight is arrived at with a formula:
The short answer is that there is no other way to *directly* measure the mass of the Sun or any other star than by observing the gravitational effects of one object on another.
You can estimate the mass of the Sun one of two ways. Both use Newton's Laws of motion. The first way uses Newton's revision of Kepler's third law, which states that the period squared or any body orbiting the Sun is proportional to its average distance from the Sun cubed. Newton generalized this for all gravitating systems. In the case of the Sun, the equation we can use is:

Mass_of_Sun=((4*pi2)/G) (a3/P2), where pi=3.14159, G is a fundamental constant, a is the radius of the Earth's orbit about the Sun, and P is the orbital period of the Earth about the Sun.

Another method uses Newton's second law and gravitation. In this case, one starts with F=m*a (where F is the force on an object, m is the mass of the object and a is the acceleration of the object due to the force). Since the gravitational force can be expressed as

F = G(MSun)(Mearth)/(R2)

where MSun and Mearth are the masses of the Sun and Earth, and R is the distance between the two, and the acceleration for a circular orbit is equal to the velocity2/R, Newton's second law can be rewritten in this case to give

Mass_of_Sun=velocity2*R/G

In both cases, putting in the values for Earth's orbital velocity, distance from Sun and the value for G gives a value of about 2 x 1030 kg for the mass of the Sun. (That's 2 with 30 zeroes after it.)

Answer 2

This is not an exact measurement, it is an estimate calculated
by the calories produced which reach the earth x distance. These
calories are produced by burning hydrogen. But the major upset in
this calculation are the atomic explosions that occur, and this
is not a constant. Also the sun looses mass as it burns, which
reduces gravity and allows the burning flames to expand. All
of this is so minimal in relation to our lifespan that we consider
sunlight to be be a constant, and it is certainly is not. So a few
kilos here or there is good enough, for the time being.

Answer 3

The sun produces energy in the form of heat and light by an atomic reaction (nuclear fission). As we know, E=mc(squared), where E-energy, m-mass and c-speed of light. This means that when there is an atomic reaction causing energy to be given out, there will be a loss of mass equivalent to that energy divided by c(squared) where c is the speed of light. From the heat and light of the sun incident on the earth, and what we know about the way that heat and light dissipate, we can estimate the energy given off my the sun every second, and therefore calculate the mass that must be lost in order to provide this energy.

Answer 4

The americans have a scale (similar to a kitchen scale) that is 2mile across and it sits on the Yukon mountain. It catches the rodioactive matter from the sun and they measure it. From this they can calculate the total mass the sun has emmetted over a period of time

Answer 5

properly, the lists in the Bible variety—there at the instant are not any 2 same lists! Gen. 40 9: Reuben, Simeon and Levi, Judah, Zebulun, Issachar, Dan, Gad, Asher, Naphtali, Joseph, Benjamin Numbers a million: Reuben, Simeon, Judah, Issachar, Zebulun, Joseph (Ephraim, Manasseh), Benjamin, Dan, Asher, Gad, Naphtali Ezekiel 40 8: Dan, Asher, Naphtali, Manasseh, Reuben, Judah, Levites (sons of Zadok), Benjamin, Simeon, Issachar, Zebulun, Gad Revelation 7: Judah, Reuben, Gad, Asher, Naphtali, Manasseh, Simeon, Levi, Issachar, Zebulun, Joseph, Benjamin the reason of this is each and every each and every now and then the descendants down the line have been named extremely than the unique individual. they are all nevertheless considered by making use of Jewish government to be literal lists (take a catalogue of the names from Revelation to an area Rabbi to substantiate). Why might Ephraim not be specially stated in Revelation (even however Joseph is, so as that tribe remains coated)? That answer may be contemporary in Isaiah 7:8: “"For the top of Aram is Damascus and the top of Damascus is Rezin (now interior yet another sixty 5 years Ephraim would be shattered, {so as that this is} not A human beings).” additionally see Hosea 4:17: "Ephraim is joined to idols; enable him on my own." (& Hos. 7:a million-sixteen) -- v. 13 says, "Destruction is theirs, for they have rebelled against Me!" Why might Dan not specially be secure? it must be using fact Judas replaced into from the tribe of Dan. Acts a million:sixteen says, “Brethren, the Scripture had to be fulfilled, which the Holy Spirit foretold by making use of the mouth of David concerning Judas, who grew to grow to be a instruction manual to those who arrested Jesus.” which would be observed to Psalm 109:8-13: “enable his days be few; enable yet another take his place of work…enable HIS POSTERITY BE shrink off; IN A FOLLOWING era enable THEIR call BE BLOTTED OUT.” Or the respond must be contemporary in Judges 17:a million-18:31, the place we are informed the Danites grew to become to idol worship and Amos 8:11-14, which says, "they're going to fall and not upward push back." i should be off course right here, yet I do experience like this is a exceedingly stable, knowledgeable wager taking those Scriptures into attention.

Answer 6

That's amazing !
Based on the numbers quoted in the answers above, that means the sun will burn for another (roughly) 15.1 million, million years ! That's HUGE !

I'm having trouble envisaging just how big the sun must physically be ! Does anyone know it's diameter ?

Answer 7

Einstein gives us a formula for converting energy to mass. All you have to do to see how much mass the Sun loses is to determine how much energy it gives off.

Answer 8

With a very large set of scales and a stop watch

Answer 9

An abestos suit, oven gloves and goggles?

Answer 10

using connected rates of change method:
i.e: dx/dy = dx/dt * dt/dy
so if they get anyone probably using much complicated scientific methods they could solve the whole thing.
