Yes, an object's weight can change even if its mass remains constant. This happens if it moves to a place with different gravity. An object on the Moon would weigh only one sixth of what it did on Earth.
As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
No, weight changes but mass remains constant irrespective of the surroundings.
the weight reduces due to change in gravity but mass remains constant
The same as on earth because mass remains constant everywhere if you are thinking about the "weight" then it will be changed .

Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
its because of the action of the wind.
Their resemblance is only a fact that the ratio of Nitrogen and Phosphorus remains constant on earth. The phosphorus and nitrogen cycle both are utilized by organisms, and in order to get the required nutrients from the atmosphere.
The percentage of nitrogen remains the same as the amount of oxygen that was used was replaced by the water vapour and carbon dioxide
A tax system that maintains a constant percentage rate on income as it rises is commonly known as a "flat tax".
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.
A Nitrogen molecule has a triple bond.So high amount of energy is needed to break down this bond.Bond dissociates naturally in occasions like lightning.So Nitrogen's reactivity is very low.Nitrogen has a little bit high molecular mass.So it has a high escape velocity.As a result of those Nitrogen remains in atmosphere in huge amount.

the concentration and of carbon dioxide and oxygen remains constant in the atmosphere because when human throw carbon dioxide out of their body so plants take it and when plants throw oxygen so human take it.
When the price level and the money wage rate change by the same percentage, the real wage rate remains constant at its full employment equilibrium level so employment remains constant and real GDP remains constant at "potential GDP" which is the quantity of real GDP at full employment.
The entropy does not remains constant if the system is not isolated.
