To achieve high rocket velocity, one must have ______?

ہائی راکٹ کی رفتار حاصل کرنے کے لئے، ایک _____؟

High exhaust velocity and low mass loss of mass during propulsion

Low exhaust velocity and higher loss of mass during propulsion

High exhaust velocity and higher loss of mass during propulsion

None of these

Rocket velocity is governed by the rocket equation, which depends on exhaust velocity and the rate of mass ejection.

Higher exhaust velocity and more mass loss (fuel ejection) produce greater thrust, resulting in higher rocket velocity.
