Answer:
Explanation:
We have here values from SI and English Units. I will convert the units to English Units.
We hace for the power P,
we have other values such 
and 
(specific weight of the water), and 0.85 for \eta
We need to figure the flow rate of the water (V) out, that is,
Where 
is the turbine efficiency, at which is,
Replacing,
With this value (the target of this question) we can also calculate the mass flow rate of the waters,
through the density and the flow rate,
converting the slugs to lbm, 1slug = 32.174lbm, we have that the mass flow rate of the water is,
Mass is indirectly proportional to gravity, as moon has less gravity mass would be greater there, if weight of the object is same!
In short, your answer would be "Moon"
Hope this helps!
Answer:-600N
Explanation:
Mass(m)=1000kg
Initial velocity(u)=25m/s
Final velocity(v)=12.5m/s
Time(t)=22 seconds
v=u+axt
12.5=25+ax22
collect like terms
12.5-25=22a
-12.5=22a
Divide both sides by 22
-12.5/22=22a/22
-0.6=a
Acceleration=-0.6
Force=mass x acceleration
Force=1000 x -0.6
Force=-600
The change of velocity is from 18.5 to 46.1 m/s or 46.1 - 18.5 = 27.6 m/s. The time of change is 2.47 s. So the acceleration is 27.6 m/s / 2.47 s = 11.17 m/s^2. The distance traveled is average velocity times time of travel.
