Jet engines work on the principle of conservation of linear momentum, which is; option [C]. According to Newton’s third law, for every action, there is an equal and opposite reaction. In a jet engine, fuel combustion generates high-speed exhaust gases expelled backwards, imparting momentum to the engine in the forward direction. This action-reaction pair conserves linear momentum. The engine accelerates forward due to the expulsion of exhaust gases, propelling the aircraft forward. This principle underpins the operation of jet engines, allowing them to generate thrust efficiently for propulsion. While conservation of energy (option A) and mass (option B) are also fundamental principles in physics, they do not directly govern the operation of jet engines. Similarly, conservation of angular momentum (option D) is not relevant to the linear motion of jet engines, which primarily rely on conservation of linear momentum for propulsion.

The period of a geostationary satellite is 24 hours, which is option [C]. A geostationary satellite orbits the Earth at the same rate as the Earth’s rotation, so it appears stationary relative to a fixed point on the Earth’s surface. This orbit is achieved when the satellite’s orbital period matches the Earth’s rotational period, which is approximately 24 hours. By maintaining this synchronous orbit, the satellite can effectively provide continuous coverage of a specific area on the Earth’s surface, making it ideal for telecommunications, weather monitoring, and other applications requiring constant observation. Option C correctly identifies the period of a geostationary satellite, emphasizing its synchronization with the Earth’s rotational period as a defining characteristic of its orbit.
