To measure gravitational mass one of the methods includes using a spring balance. a balance is a type of scale that is different because it uses known mass to measure the unknown mass. so technically the method measures the weight.
also if you just want to know normal mass then just weigh the object on the scales because technically speaking when you want to see your weight you are actually seeing your mass. because mass never changes whilst weight is from the result of gravity and always changes, so yeah. I hope thos actually makes some sort of sense
The third answer is the one you want. You have to have an adjustable density. All other things being equal, if the tanks you use for holding just water when filled with water will let the sub sink, because the sub is made of a dense metal like iron or steel.
If on the other hand you fill these tanks with air, the net density will be below one and the sub will rise.
Answer:
When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. ” Mono-” indicates one, “Di-” indicates two, “Tri-” is three, “Tetra-” is four, “Penta-” is five, and “Hexa-” is six, “Hepta-” is seven, “Octo-” is eight, “Nona-” is nine, and “Deca-” is ten.
