The flow will be laminar if Reynold's number
is less than 2000.
Use the Reynold's formula and rearrange to calculate velocity of water in the pipe.
Where, 
is velocity of the fluid, 
is the diameter of pipe, and 
is the kinematic viscosity i.e. 
for water at 288.7 K from Appendix.
So, velocity is:
The flow rate <em>Q</em>:

Where A is the area of cross section of pipe.
The time taken to fill is:
Where V is the capacity of the tank.
This is an elastic collision
bcuz i think they move apart after the collision
sorry if im wrong
Explanation:
Earth rotates in prograde mation.As viewed from the north pole star Polaris.Earth turns counterclockwise,, the north pole is point in the northern,, Hemisphere where Earth's Axis of rotation meets it's surface
Answer:
The sun looks bigger than other stars because it is closer to the Earth, distance makes it look larger
Angles, they line up their pool que with the pocket and make the shot
