Question

1. (a) Calculate the weight of the body whose mass is 30 kg. Take g = 10 m/s.
(b) What is meant by thrust?​

Answer 1

Answer:

☛W = m× g

= 30×10=300

☛Thrust is a mechanical force, so the propulsion system must be in physical contact with a working fluid to produce thrust.

Answer 2

Answer:

a) weight = mg

= 30×10

=300.

b) Thrust is the force which moves an aircraft through the air. Thrust is used to overcome the drag of an airplane, and to overcome the weight of a rocket. ... The engine does work on the gas and accelerates the gas to the rear of the engine; the thrust is generated in the opposite direction from the accelerated gas.
