Question

what is relative density ???​

Answer 1

Answer:

the ratio of the density of a substance to the density of a standard, usually water for a liquid or solid, and air for a gas.

Answer 2

Explanation:

Mass (m) = 2 kg

⠀⠀⠀Force (F) = 20 N

▬▬▬▬▬▬▬▬▬▬▬

We Have to Find Acceleration

\huge \boxed{ \red { \boxed { \bf Force = Mass \times Acceleration }}}Force=Mass×Acceleration

Substituting the Values

\dashrightarrow \bf20 = 2 \times a⇢20=2×a

\dashrightarrow \bf a = \cancel\dfrac{20}{2}⇢a=220

\dashrightarrow \bf a = 10 \: m \: {s}^{2}⇢a=10ms2

Therefore, Acceleration = 10m/s²

\bf F = m \times aF=m×a

\bf v^{2} - u^{2} = 2asv2−u2=2as

\bf v = u + atv=u+at

\bf S = ut + \dfrac{1}{2} at^{2}S=ut+21at2
