Answer 1

Explanation:

any thing that occupies space and has mass is called matter.........

Answer 2

Explanation:

Let Units of Force, Length and Time are F, L and T respectively.

density = Mass / Volume = (Force/Acceleration)/Volume .................(1)

Acceleration = (Change of velocity ) / Time = (distance /Time) /Time ..............(2)

from eqn.(2), we can write uint of acceleration = L / T2 ....................(3)

hence using unit of acceleration and using eqn.(1), unit of mass = begin mathsize 12px style fraction numerator F over denominator begin display style open parentheses bevelled fraction numerator begin display style L end style over denominator begin display style T squared space space end style end fraction close parentheses space cross times L cubed space end style end fraction space equals space fraction numerator F space cross times T squared over denominator L to the power of 4 end fraction end style
