SRP revolves around the idea that electromagnetic waves are mass-less, but exhibit mass-like properties. The photons in light emitted from the Sun move at the speed of light and have momentum. Because they have momentum, when they hit other objects, they transfer momentum to that object, giving it a boost in velocity.
The flow of electric charges that is observed in electrolytes
The difference between the rocket speed and the propellant speed is called the exhaust speed
The equivalence ratio is given by the formula:
The stoichiometric ratio is the optimum amount where the reaction proceeds to completion:
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s. It depends strongly on temperature as well as the medium through which a sound wave is propagating – WIKIPEDIA
