The hose material is very elastic.
Since the hose is at rest, it tends to stay at rest.
The force exerted on the water equals the mass of the water times its acceleration.

Rolling Friction
Fluid Friction
Sliding Friction
When you jump out of a plane to go skydiving, you have a parachute so you can safely land. Which answer choice explains why the parachute helps you land safely?
While gravity pulls you down very quickly, Air Resistance (fluid friction) pushes back against gravity and your parachute, slowing you down
While gravity pushes you down very slowly, Air Resistance (fluid friction) pulls back against gravity and your parachute, which means you can land safely
When you have a parachute gravity is not able to pull you down as fast as it normally can
The parachute will get caught on something on your way down which will save your life
