Answer:
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
Answer:
<em>Height = 5.65 km</em>
Explanation:
is the circumference or we can say measures the boundary of hemisphere of friction-less ice that he is sitting on.
So, the height will be = 2 x 3.14 x (30)^2 = 5654.7 m = 5.65 km
Concept: The frequency won't change in water or in air.
Since wavelength x frequency = speed, wavelength is proportional to speed.
So, Middle C has a longer wavelength in water than in air.

Answer:
V = 1.45x10^3 m/s
Explanation:
number of days in sec = 1.02days * 86400s = 88128 s
Mass of Mars is 6.42*10^23 Kg
gravitational constant G = 6.674*10^{-11}
