Answer:
Explanation:
a ) The centre of mass of a can filled completely with any liquid of any mass lies at the center of the can or at height h /2 where h is height of the can . So centre of mass of can of mass .140 kg of height 12 cm will lie at height 6 cm . Similarly center of mass of its content will also lie at height 6 cm that is center point of the content .
Hence overall center of mass of can along with its content will lie at height 6 cm initially .
b )
After the can loses all the soda , can becomes empty . Hence its center of mass will lie at its center again .
c ) Its center of mass remains unchanged as the soda drains out completely .
d ) When soda starts draining out of the can , its lower part becomes heavier than the upper part . Hence its center of mass moves downwards . Its height is lowered . As height of soda is lowered in the can , center of mass also is lowered . It reaches its lowest point when soda in the can reaches half the height or when the can is half filled .
After that center of mass again starts rising upwards until the can is completely empty .
