In a jet propulsion

In a jet propulsion Correct Answer The propulsive matter is caused to flow around the propelled body

Jet propulsion is the propulsion of an object in one direction, produced by ejecting a jet of fluid in the opposite direction.
By Newton's third law, the moving body is propelled in the opposite direction to the jet.

The force exerted by a jet of water impinging normally on a plate which due to the impact of jet, moves in the direction of jet with a velocity v is
Water, having a density of 1000 kg/m3, leave from a nozzle with a velocity of 10 m/s and the jet strikes a bucket mounted on a Pelton wheel. The wheel rotates at 10 rad/s. The mean diameter of the wheel is 1 m. The jet is split into two equal streams by the bucket, such that each stream is deflected by 120°, as shown in the figure. Friction in the bucket may be neglected. Magnitude of the torque exerted by the water on the wheel, per unit mass flow rate of the incoming jet, is
The important characteristics about Jet stream are- Jet streams are narrow, fast-flowing, meandering air currents in the atmospheres of some planets, including Earth. The strongest jet streams are subtropical jets at the higher altitude and somewhat weaker are polar jets.
A statement is given below in the question followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Statement: Jet Airways has defaulted on salary payments again. The cash-strapped airline on Wednesday sought over 10 more days from its employees to pay balance 25 per cent of their salaries for August. Jet Airways had paid 50 per cent of August salaries to its employees on September 11 and the rest was to be paid on Wednesday. But it could pay only half of the balance amount.  Courses of action: I. The cash-strapped airline, which is struggling to meet its cost of operations, had earlier attempted to cut salaries of its employees, but the move was met with stiff resistance that forced it to defer the plan.  II. Jet Airways will today remit half of the second installment of pending emoluments of its pilots, AMEs and senior management for August 2018. III. While the management regrets the attendant inconvenience, it also appreciates the continued support and understanding of its employees.
