Density is mass over volume. Density is also a charecteristic property wich defines a substance and two different substance cant have the same charasteristic property.
To be honest, there's no sure way to answer that, because you haven't defined your terms and we can't be sure of what j or s might be.
Tell you what I'll do:. I'll assume definitions for j and s, and then I'll answer the question that I invented.
Assume that j stands for Joule, the unit of energy. And assume that s stands for 'second', the unit of time.
Then j/s is the rate of transferring energy or doing work.
Its unit is the Watt, equivalent to 1 Joule per second.
In your system of notation, it would be 'w' .
yes because your mass doesn't change but your weight can
ex- if you travel to Saturn your weight would change but your mass would stay the same
You would multiply the speed by the time. So the answer would be 840 miles.
