Q:

Through inlet orifices, which are facing the direction of motion of the ship, the water from the sea can be taken by the pump.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: Through inlet orifices, which are facing the direction of motion of the ship, the water from the sea can be taken by the pump. We can also take the sea water from the pump when the inlet orifices are at right angles with respect to the motion of the ship.

Q:

The inlet orifices are at what angle with the motion of the ship?

A) 0 B) 30
C) 60 D) 90
 
Answer & Explanation Answer: D) 90

Explanation: The inlet orifices are at right angles with respect to the motion of the ship. The main purpose of the inlet orifice is to take water from the sea by the pump. Thus, the correct angle at which it moves is 90 degress.

Q:

The movement of ships and boats in water is due to __________

A) Water currents B) Jet propulsion
C) Mass flow rate D) Volumetric changes
 
Answer & Explanation Answer: B) Jet propulsion

Explanation: The movement of ships and boats in water is due to Jet propulsion. This mainly happens at the back of the ship or boat. It occurs as it exerts force on the ship and the boat. Thus, the correct option is Jet propulsion.

Q:

Jet propulsion works on the principle of________

A) Newton’s first law B) Newton’s second law
C) Newton’s third law D) Thermodynamic properties
 
Answer & Explanation Answer: C) Newton’s third law

Explanation: Jet propulsion works on the principle of Newton’s third law. Newton’s third law states that for every action, there is an equal and opposite reaction. Thus, the correct option is Newton’s third law.

Q:

The propulsive force drives the jet in the ________

A) Backward direction B) Forward direction
C) Perpendicular direction D) Parallel movement
 
Answer & Explanation Answer: B) Forward direction

Explanation: Force exerted by a jet on a moving plate happens in three cases. The three cases are classified depending on their position. The propulsive force drives the jet in the forward direction. A good example is the aircraft or a boat.

Q:

Component of velocity in direction of jet is -VCos?

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: Component of velocity in direction of jet is -VCos?. The negative sign indicates the that the taken velocity at the outlet is opposite to the jet of water coming out from the nozzle. Thus, it is true.

Q:

A jet after striking a smooth plate comes out with a __________ velocity.

A) Increased B) Decreased
C) Same D) Zero
 
Answer & Explanation Answer: C) Same

Explanation: Force exerted by a jet on a stationery plate happens in three cases. The three cases are classified depending on their position. After it strikes a smooth plate, its velocity remains the same
