Answer:
Escape speed is the minimum speed with which a mass should be projected from the Earth's surface in order to escape Earth's gravitation field. Escape speed, also known as escape velocity is defined as: ... ve is the escape speed. G is the universal gravitational constant (G≅6.67×10-11 m3kg-1s-2)

★ Physics is a branch of science. It is one of the most fundamental scientific disciplines. The main goal of physics is to explain how things move in space and time and understand how the universe behaves. It studies matter, forces and their effects.
★ The minimum velocity that a moving body (such as a rocket) must have to escape from the gravitational field of a celestial body (such as the earth) and move outward into space.
★ Surface tension could be defined as the property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of the water molecules.
★ An isothermal process is a thermodynamic process, in which the temperature of the system remains constant: ΔT=0. The change in temperature remains zero in the process. Any system where the temperature is maintained constant is an example of the isothermal process.
