Answer:9.8 m/s²
Explanation:
It was going at 9.8m/s² as this is the acceleration of an object due to gravity
when an object falls it accelerates at a consant and uniform speed which is 9.8m/s²
Hydrogen.
When they run out of hydrogen fuels in its cores, fusion stops. The collapse of the core causes the temperature to increase in it and around it. Eventually the heat of collapse is enough for the shell of hydrogen are the core to fuse and it turns into a red star.

Answer:50![ms^{-1}](https://tex.z-dn.net/?f=ms%5E%7B-1%7D)
</h2>
Explanation:
Let
be the airspeed.
Let
be the cross wind speed.
We know that,ground speed is the vector sum of airspeed and cross wind speed and airspeed is perpendicular to cross wind speed.
If
and
are two perpendicular vectors,the resultant vector has the magnitude ![\sqrt{|v|_{1}^{2}+|v|_{2}^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%7Cv%7C_%7B1%7D%5E%7B2%7D%2B%7Cv%7C_%7B2%7D%5E%7B2%7D%7D)
Given,
![v_{a}=40ms^{-1}\\v_{c}=30ms^{-1}](https://tex.z-dn.net/?f=v_%7Ba%7D%3D40ms%5E%7B-1%7D%5C%5Cv_%7Bc%7D%3D30ms%5E%7B-1%7D)
So,the ground speed is ![\sqrt{40^{2}+30^{2}}=\sqrt{2500}=50ms^{-1}](https://tex.z-dn.net/?f=%5Csqrt%7B40%5E%7B2%7D%2B30%5E%7B2%7D%7D%3D%5Csqrt%7B2500%7D%3D50ms%5E%7B-1%7D)
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
