Answer:
neutral
Explanation:
3p - 3e = 0 and that leaves 2 neutrons so it will be neutral
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
Speed is given as distance divided by time. I think that first you should simplify the two rates 58/2=29km/hr and 71/4=17.75km/hr After that find the mean or average which is (29+17.75)/2=23.375km/hr
Therefore it is safe to say that the average speed of the train is 23.375km/hr. I am not sure about this.
