A water hose has a flow rate of 3.0 kg/s of water.If the velocity of the water as it leaves the hose is 5.0 m/s,then the force to hold the hose is
A) 15 N.
B) 26 N.
C) 30 N.
D) 45 N.
E) 57 N.

The force required to hold the hose can be calculated using the formula F = Δ(mv)/Δt = m * v, where m is the mass flow rate (3.0 kg/s) and v is the velocity (5.0 m/s). Thus, F = 3.0 kg/s * 5.0 m/s = 15 N.
