Since Power is equal to the product of Force and Displacement all over time, George needs 6.86 W of power to push the wheelbarrow. Power can also be calculated by multiplying Force applied on the object and the speed of the object being applied of the force.
I think the question need to use extrapolation. FInd the linear function of the first and second data. And then, the anwser is 5.4 liters.
Answer:
Explanation:
a net force of F causes a cart with a mass of M to accelerate at 48 cm/s/s.
F = M x 48
Mass M = F / 48
a )
When force = 2F and mass = M
Acceleration = force / mass
= 2F /F/48
= 48 X 2 = 96 cm/s²
b )
When force = F and mass = 2M
Acceleration = force / mass
= F /2F/48
= 24 cm/s²
c )
When force = 2F and mass = 2M
Acceleration = force / mass
= 2F /2F/48
= 48 cm/s
d )
When force = 2F and mass = 4M
Acceleration = force / mass
= 2F /4F/48
= 24 cm/s
e)
When force = 4F and mass = 2M
Acceleration = force / mass
= 4F / 2M
= 4F / 2 F/48
= 48 x 2
Acceleration = 96 cm/s²
Answer:
1.12 m
0.08291 m
Explanation:
u = Upstream velocity = 0.4 m/s
Re = Reynold's number = 
(turbulent)
= Viscosity of water = 
Here the flow is turbulent so we have the relation
The approximate location downstream from the leading edge where the boundary layer becomes turbulent is 1.4 m
Boundary layer thickness relation is given by
The boundary layer thickness is 0.08291 m
