Answer:
d)no unit
Explanation:
refractive index is a unit less quantity.
Explanation:
Area=1.5(1.5)=2.25m^2
Force of gravity=10N
\begin{gathered}\\ \sf\longmapsto Pressure=\dfrac{Force}{Area}\end{gathered}
⟼Pressure=
Area
Force
\begin{gathered}\\ \sf\longmapsto Pressure=\dfrac{10}{2.25}\end{gathered}
⟼Pressure=
2.25
10
\begin{gathered}\\ \sf\longmapsto Pressure=4.4Pa\end{gathered}
⟼Pressure=4.4Pa
You have to do distance÷time= 250÷5=50 mph
Answer:total mechanical energy of the system to
Explanation:
Total mechanical energy=kinetic energy+potential energy
Electricity is the flow of electrical power or charge.
