w=pg.
It means w is directly proportional to gravity. Hence w will not vary anywhere on the earth as gravitational acceleration is assumed more or less constant all over the earth
But this force of gravity varies on other planets hence sp.wt will change too.
Here 'other places' refers to places including earth and universe.
Answer must be B and C.

I think the answer should be B and C because the value of g change from place to place even on earth so it does not remain contact at every place. And specific weight depends upon g and mass So it will change from place to place.

Mass remains the same everywhere.
But, SP. Weight (N/mm^2) changes from place to place.

B should be the correct answer.

B and C both correct.
Because Sp.Wt =density (multiply) acceleration. Acceleration is variable place to place.
Because Sp.Wt =density (multiply) acceleration. Acceleration is variable place to place.

It should be B, as the acc Due to gravity changes from place to place even on our earth, so the Specific weight Also changes in accordance.

I think it changes on another planet.

So at= wt. /vol, with an increase in temperature Specific weight Decrease because Temp increase, vol. Of fluid increase.

Sp wt w=pg.
It depends on g only so B, C correct.
It depends on g only so B, C correct.

As the change of value of g is negligible on earth, so the correct answer will only be B.
