Doesn't matter to the balloon. The amount to be lifted is identical and in this case air resistance is not a factor.
hydrogen! Iron+acid=hydrogen
Because they each weigh 300 pounds, they weigh the same, thus neither is heavier than the other.
Iron.
they are both equal in weight, there are jsut more feathers. Bot still weigh the same as a ton is a measurement of weight
Sattin does not refer to a type of steel, it is a degree of finish. Therefore-considering that we do not know what particular steel is sattin finished, this question can't be answerd.
Because they have the same mass, the same force would be required to lift both 1kg of steel and 1kg of feathers. The "ease" of lifting the two masses would be equal.
Density. The mass of a pound of any two materials on Earth is always the same. However, a pound of steel has far less volume for a pound than a pound of feathers. Thus, steel is far, far denser than feathers are.
the material used is called sandpaper
hydrogen! Iron+acid=hydrogen
are you being serious, if you are no, 15 is not heavier than 18 pounds of feathers.
steel copper aluminum
Because they each weigh 300 pounds, they weigh the same, thus neither is heavier than the other.
The acid in the fruit reacts with the steel of the can to make hydrogen gas. This defect is known as a 'hydrogen swell'.
yes
no feathers do cause Jacob Davis said so
It was a cheaper and easier way to make steel.
Two pounds of feathers are heavier than one pond of steel, but the feathers are less dense than the steel so two pounds of feathers have a greater volume than one pound of steel. Density determines weather an object will float or sink. If an object can float on water it has to be less than 1. If the object is more dense than water than it will sink.
