Answer 1

#28

Fluid always flow from higher pressure to lower pressure so as we can see the figure liquid is coming out of the spray bottle so it clearly shows that the pressure outside the tube will be lower than the pressure inside the tube.

Momentum is defined as product of mass and its velocity

so here we will have

`P = mv`

here we have

`m = 38 kg`

`v = 2.2 m/s`

so we will have

`P = (38 kg)(2.2 m/s)`

`P = 83.6 kg m/s`
