So then we would get nine point two eight forecast after broke nine pounds. And now, in order to get it in terms of tongues to a poor intensity for nine pounds, one Thanh is going to be two thousand Hell's thes.
They're gonna cancel. So our family answer is going to be four point six for two ten Sentinel six tons. That's a very big number now in part beast, where are asked the lifetime of the Sun. Then if it is actually losing four point six times, sent six tons of matter per second remember recalculated for per second.
So we need to know the mess off his son through Be Ansel to be intense for this part. The message says one point nine nine times. Thank you for charity. Kilograms Armless called him. So s so Then you're asking You're looking for racial, right? I'm so s divided by the mass that we capture legal matter though per second. So let me do one for nine nine to total mess Kilogrammes divided by getting killed rooms. Right, Let me write down the kilogram version of what we calculated for the mass.
I'm client tend to borrow knife, kill rams. But this was for a second. Remember this so that when we do buy this number by this, kilograms are gonna cancel. We're gonna have is in canopy in seconds. Four point seven to ten. Center for twenty seconds. Now from the second. Since it's a big number, let's convert this two years.
As you know, four point seven two times ten to four twenty seconds. Let's do the minute first. So one minute is going to be sixty seconds and then off. Show that the statement in the text is correct: namely, that roughly million tons of hydrogen must be converted to helium in the Sun each second to explain its energy output.
Does this answer agree with the lifetime you calculated in Exercise Every second, the Sun converts 4 million tons of matter to energy. Compare your answer with the lifetime of the Sun so far. Raymond Davis Jr. During his experiment, he found that one neutrino reacted with a chlorine atom to produce one argon atom each day. As an Amazon Associate we earn from qualifying purchases.

In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy. Mass of 4 H atoms: 4. This small fraction of the mass is converted into energy. So we want to know how many kilograms of hydrogen undergo fusion per second in the Sun. So we are going to multiply 1 kilogram for every 6.
So we have a kilogram for this many joules times 4. Then in part b , we are asked for how long will this fusion carry on before the Sun changes its character? Now, we are told that 90 percent of the Sun is hydrogen and so we can figure out, how much hydrogen there is by going 0. So that's 0. And we know that in every second, there are 6. And so for every second, we have this many kilograms fusing multiplied by this many kilograms of hydrogen that are available and then this would give us the number of seconds that the Sun can do fusion for but let's express this in years because we can understand years a bit better although this number is so big, it's hard to understand anyway.
