Define Hydrogen Rocket?
The reaction chamber of a rocket engine is supplied with a mass flow rate m of sufficient oxygen and hydrogen to allow complete burning of the fuel and the cross section of the chamber is A and the pressure at the cross section is P with temperature T. Evaluate the force that this chamber is able to provide.
Describe Acceleration In physics, acceleration is the rate at that the velocity of a body changes with time. In common, velocity and acceleration are vector quantities, along w
A VDR is a special type of resistor that changes its resistance with rise in voltage. It has a very high resistance at low voltage (below the trigger voltage) and very low resista
