Prithvi II is an indigenously developed nuclear capable missile. With a strike range of 350 km, the Prithvi-II is capable of carrying 500 kg to 1,000 kg of warheads and is thrusted by liquid propulsion twin engines. It uses advanced inertial guidance system with manoeuvring trajectory to hit its target. It is a short range surface to surface missile.

Inducted into Indian armed forces in 2003, the nine-metre-tall, single-stage liquid-fuelled Prithvi-II is the first missile to be developed by the DRDO under the Integrated Guided Missile Development Programme.

Project Loon is a research and development project being developed by X (formerly Google X) with the mission of providing Internet access to rural and remote areas. Aquila by Facebook is a solar power plane that beams internet connectivity from the Sky. White Fi by Microsoft uses unused spectrum to provide connectivity.

: Aquila is the code name of the unmanned solar-powered drone developed by Facebook. The company plans to use a linked network of the drones to provide internet access to large rural areas. Recently Facebook completed the first successful flight of Aquila. However, as with its Internet.org project, Facebook will not be dealing with customers directly, instead partnering with local ISPs to offer the services.

All the statements are correct. Ketosis is a normal metabolic process. When the body does not have enough glucose for energy, it burns stored fats instead; this results in a build-up of acids called ketones within the body.

Some people encourage ketosis by following a diet called the ketogenic or low-carb diet. The aim of the diet is to try and burn unwanted fat by forcing the body to rely on fat for energy, rather than carbohydrates.

Ketosis is also commonly observed in patients with diabetes, as the process can occur if the body does not have enough insulin or is not using insulin correctly.

ELISA Pathfinder is paving the way for future missions by testing in flight the very concept of gravitational wave detection: it will put two test masses in a near-perfect gravitational free-fall and control and measure their motion with unprecedented accuracy. It’s objective is to detect thegravitational waves and not the dark matter and Dark Energy. LISA Pathfinder is an ESA mission, which also carries a NASA payload. Only feasible in space LISA pathfinder is a pioneer mission. Not only are these technologies new, they cannot be properly verified on the ground. This is because Earth’s gravity and environment would hamper the test results.
