Any help will be appreciated:)
1) When a soda bottle is opened,gas bubbles rise up. Will they continue to rise if the bottle slips and starts falling?
(Note:-I've noo idea what they mean!)
2) An hourglass is kept on a weighing machine. Will the weight recorded be more if all the sand is in the lower compartment,or if sand gradually falls from one compartment to the other?
(Note:- I think this has something to do with impulse. Weight recorded should be more in the 2nd case,because an additional impulse is exerted on the weighing machine by the falling sand. I can be completely wrong of course,hehe.)
Please help!
