Is the sun getting heavier or lighter as time goes on explain why?

there are three well known processes that each involve an ongoing change in the mass of the sun.
the sun radiates heat, thus losing energy and thus losing mass. the rate of mass loss by this process can be calculated quite easily and accurately.
the sun blows off matter continuously but somewhat irregularly. this flow of material is known as the solar wind. in this way the sun loses mass.
the sun still collects infalling stray chunks of loose material called meteors and in this way increases in mass.
i do not know the relative sizes of these three processes.

How are the elements carbon nitrogen and oxygen produced in stars like the sun?
These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.
How does a lantern float in the sky?
The fire inside produces hot air, hot air is lighter than clod air so it goes up!
What are the advantages of a space shuttle when it goes into space or even when it is getting ready to do a launch into space?
the shuttle goes fast and when it is in space,it become less weight so it goes easier on the space shuttle.
A sand bag is drooped froma hot air balloon and the balloon rises explain why this happens?
It has less weight holding it down, so it goes higher.
Why does ash from burning wood goes up into the air instead of going downwards even though gravity causes all things to fall downwards?
Air. Density. Lighter or less dense objects float. The ash floats on the hot (less dense) air.
What happens to the speed of a wave as the wave goes from one medium to another?
It depends whether the new medium is "heavier" or "lighter" than the previous medium. If it is "heavier" then the wave slows down. If it is "lighter" the wave speeds up.
What other fabric looks and goes well with velvet or velour's?
satin, silk and lace and sometimes even cotton, georgette go well with satin. Basically think of lighter fabrics to contrast with heavier velvet.
Suppose sand gravel and clay are being carried by a river As the water enters a lake and slows down In what order will these sediments settle out of the water explain why they settel in that order?
As the current slows and goes around bends the heavier silt always settles first. This is the factor that causes 'meanders' in slow moving rivers. The lighter, smaller fragments are carried out to the edge of the delta.
Why Is it harder to stop a heavy football player rushing the ball than it is to stop a lighter one?
Because the heavier football player has a much higher momentum which is product of mass and velocity. To cancel the momentum of a heavier football player one must achieve the same momentum at impact. A lighter player can only do that by increasing his velocity.Momentum = mass x velocityIf a football player weighed 100 Kg and was traveling at 5 m/s (11 miles per hour). A 50 Kg person would have to impact the heavier football player at a speed of 10 m/s (22 miles per hour) to cancel the inertia of the heavier football player.As the heavier football player goes faster it becomes increasingly difficult to stop them. You can also take several lighter players by combining their mass to stop the forward momentum of the heavier football player.
What happens when a ball with a heavier mass goes farther than a ball with a lighter mass when you put both of the objects on a ramp which is a door stopper?
Actually the heavier ball give all kinectic energy to the smaller ball which in turn also moves forward with the same velocity as the other one ,therefore kinectic energy is conserved.
Will a larger bike always have more momentum than a smaller bike?
No.Momentum is a combination of weight and speed, so something lighter travelling faster can easily have the same momentum as something heavier travelling slower.So, if the bigger bike also is the heavier bike, and the bikes are always travelling at the same speed, then it will have more momentum.Otherwise, anything goes.
What do you do if your lighter goes through the wash and dryer?
If your dryer didn't explode, try lighting your lighter. If your lighter lights, then you have nothing to worry about. If it doesn't go buy a new lighter.
Why are all chemicals in the atmosphere gases?
Gases are lighter than solids and liquids, so light that they can be in our atmosphere. Example, when water evaporates it is light and goes up into our atmosphere where it will condense to form liquid, which is now heavier and more dense and therefore falls
Does a heavier person ride a skateboard faster than a lighter person?
The short answer is YES! Bigger wheels mean that if the bearing are spinning the same speed, the outside of the wheel is spinning faster than a small wheel.
How do you weigh the pumpkins on great pumpkin island?
Place them on the balance two at at time, starting with the two on the far left. Each time, leave the heavier one (goes lower) and take off the lighter one. You have to weigh all 7 to get the right one for Lucy.
Why does yoke go to center when boiling an egg?
It goes to the center as the yolk is heavier.
In gymnastics what is a counter balance?
The idea of counterbalancing is like see-saws or scales. You use the weight a part of your body in different positions to equal the the lighter or heavier part of your body to. Example: When you do a arabesque or a scale you lean forward as your leg goes up backwards to counterbalance your weight.
