The mass Mt of gunpowder burned per unit time in the rocket engine chamber depends on the pressure P according to the law Mt = APn. Find the exponent n if, when the cross-section of the engine nozzle is reduced by a factor of 2, the pressure in the chamber increases by a factor of 4. The speed of gas flow from the nozzle is proportional to the pressure in the chamber P.
