Yes because it glows when it glows the tube expands to create space for it to glow
since it is balanced the net moment about the pivot is zero. The meter stick center of gravity mass is at the 50 cm point, or 25 cm to the right of the pivot. 150 x 25 = mass of stick x 25 ; so mass is also 150 grams
The mass of the whole doesn't change, it's simply the sum of the mass of the solute and the mass of the solvent.
The answer will depend on how wide and thick it is.
It is a physical change.
no it doesnt gain mass at allIt can change the bio mass. But cannot change the mass of earth as it uses resources within earth
Europium can be used in an assortment of glow in the dark paints. The metal itself does not glow.Europium:Symbol: EuAtomic Mass: 151.9Atomic Number: 63

Mass does not change with temperature
in mass they are. depends on where you are. in mass they are. depends on where you are.

A bag of sugar !
At 500 mm, halfway through the width of the stick.
In this case mass doesn't change.
Your mass will not change, but your weight will.
The mass will hardly change. What changes is the weight.The mass will hardly change. What changes is the weight.The mass will hardly change. What changes is the weight.The mass will hardly change. What changes is the weight.
