This is because a milk bottle is transparent but if it has milk in it - (milk's opaque) then you wont be able to see through it which will make the shadow darker.
An empty bottle has less mass than a full bottle. This means that the empty bottle has less force to overcome when lifted which corresponds to less work to lift it.
full or empty?
Yes I do, and why?
It is easier to squeeze an empty bottle because there is less resistance from the air inside the bottle compared to the water. The water in a full bottle creates more pressure and resistance when you try to squeeze it.
$20-$50 for empty bottle, $50 - $100 for full bottle
To fill an empty argon bottle from a full one using a manifold, connect the full bottle to the manifold with a high-pressure hose. Open the valves on both bottles, allowing the argon gas to flow from the full bottle to the empty one. Monitor the pressure gauge to ensure the transfer is complete and disconnect the bottles once done.
err, yes, because: bottle mass + soda mass > bottle mass
The mass of the bottle will remain the same whether it's full or empty however, the weight will change.
The principal of inertia merely says that a body will remain ar rest until moved by a force. The force required to lift a bottle has to be equal and opposite to the force of gravity pulling it down which is proportional to its mass. So the more mass in the bottle the more force required to lift it.
After you get the fishing rod, catch two fish near the cat. The cat runs to the shop. Go to the shop and you get a bottle full of milk. Use the milk and you have and empty bottle
full bottles are top heavy. half full one's are not. The above answer is only true if the bottle is shaped so there is more water in the top half then the bottom half when full. Otherwise the bottle is not top heavy. It is just as heavy (or sometimes only slightly less heavy) on top as it is on bottom. Where as a half empty bottle has a heavier base to keep it from toppling over easier. The same principle is used in the engineering of skyscrapers. The foundation goes deep into the ground and weighs many times the weight of the top so it will not fall because of a windy day.
