Then the NaCl(aq) will have different chemical properties(reactivity,etc) than NaCl(s) right?

Then does the ion surrounded by water molecules forms another compound?

When you dissolve, for example, NaCl in water, then you get "NaCl in water" solution. Will the "NaCl in water " solution have different chemical properties from its constituents(NaCl and H2O)? i.e. is a "NaCl in water" solution a new compound with respect to NaCl or H2O ? And is the ion...

Is this correct? "The systematic error in a measuring instrument due to non-uniform or wrongly marked graduation due to which a measurement may be less or greater than actual measurement is called zero error of the measuring instrument". Another one: The measuring instruments are combination...

By saying passing through rest frame, I didn't mean that the object got through another physical body but now, I too agree that it's bad to say it "passes through" a rest frame. It would seem better to say "the particle instantaneously shares a rest frame with the observer".

Can anyone tell the meaning of frame? Just for confirmation.:wink:

At maximum height, the velocity of the ball is equal to 0, but it doesn't continuously remain at zero for a continuous time period, even not for the millionth part of second….but the ball simply passes through rest. Look at the velocity-time graph in the picture below. At point B , when the...

At each extreme of the pendulum the velocity is equal to zero therefore the magnitude of velocity vector is also equal to zero. But the gravitational acceleration is constant at every position of the pendulum. Therefore, the object is not completely at rest but momentarily at rest as it will...

Its correct because it is momentarily at rest and not completely at rest. This satisfies Newton's law.

When a ball is thrown upward it becomes at rest at maximum height, at this it is not in equilibrium although it is at rest. It is not at equilibrium because force of gravity is acting on it? Still I cannot find good explanation from exam point of view.I also cannot find the figure/diagram.

I don't get it

Then is it correct to say infinite pieces instead of almost infinite pieces in that video?

I remember hearing someone say "almost infinite" in this video. As someone who hasn't studied very much math, "almost infinite" sounds like nonsense. Either something ends or it doesn't, there really isn't a spectrum of unending-ness. In this video he says that ''almost infinite'' pieces of...
