Answer:
0.556 Watts
Explanation:
w = Weight of object = 762 N
s = Distance = 5 m
t = Time taken = 29 seconds
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s²
Equation of motion

Mass of the body

Force required to move the body

Velocity of object

Power

∴ Amount of power required to move the object is 0.556 Watts

Answer:
The correct answer is option 'a': 0.046 meters.
Explanation:
We know that the exit velocity of a jet of water is given by Torricelli's law as

where
'v' is velocity of head
'g' is acceleration due to gravity
'h' is the head under which the jet falls
Now since the jet rises to a head of 90 meters above ground thus from conservation of energy principle it must have fallen through a head of 90 meters.
Applying the values in above equation we get the exit velocity as

now we know the relation between discharge and velocity as dictated by contuinity equation is

Applying values in the above equation and solving for area we get

The circular area is related to diameter as

Thus the diameter of the nozzle is 0.246 meters
