False.
Force is found by multiplying mass of an object by its acceleration.
F = mass * acceleration
 
        
             
        
        
        
Hey there! 
The correct answer to your question is: Intensity
The rate which light flows through a given area of space is referred to as its intensity. I<span>ntensity and wavelength are two factors which contribute to light energy.</span>

Given,
The initial inside diameter of the pipe, d₁=4.50 cm=0.045 m
The initial speed of the water, v₁=12.5 m/s
The diameter of the pipe at a later position, d₂=6.25 cm=0.065 m
From the continuity equation,

Where A₁ is the area of the cross-section at the initial position, A₂ is the area of the cross-section of the pipe at a later position, and v₂ is the flow rate of the water at the later position. 
On substituting the known values,

Thus, the flow rate of the water at the later position is 5.99 m/s
