Answer:
F=547.5
Explanation:
To Find the answer you have to remember the Formula for work. Work= Force* distance, because we are not finding work we have to fill in the variables or rearrange the formula to Force= Work/Distance
Work= 16,700
Distance=30.5M
Force=?
So,
16,700=F*30.5
Now you isolate the variable by dividing both sides by 30.5
or
Force=16,700J/30.5M
and you get F=547.5
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
Answer:
Normal force=mg
Explanation:
The reaction force of weight is the normal force.
in order to find the normal for we need to write all the forces and set it equal to the net force:
N-mg=ma (since it is a constant speed the a=0)
N=mg
B is a right answer, and maybe C? I think so.
Answer: It goes inside filling most of it .
Explanation: This happens because the bottle is empty and the bucket is full of water.
