Force required is 100 N
<u>Given that;</u>
Rate of acceleration = 5 m/s²
Mass of object = 20kg
<u>Find:</u>
Force required
<u>Computation:</u>
Force = Mass × Acceleration
Force required = Rate of acceleration × Mass of object
Force required = 20 × 5
Force required = 100 N

The answer is D, by adding the most water you will get the most diluted solution.
Answer:
I think the answer is C but I'm probably wrong.
Answer: The maximum velocity of fluid flowing in a circular channel occurs at the centre of the channel.
Explanation: starting from the material balance equation and going through Newton's law of viscosity.
The velocity profile of a circular channel is
V(r) = Vmax(1 - (r/R)^2))
V(r) is velocity at any point in the circular channel along the radial direction starting from r=0 at the centre and r=R at the internal side of the circular channel.
So, the maximum obtainable from that distribution is at the centre where r=0 and V(r) = Vmax.
