What else can I help you with?
Why does the weight of rocket change during liftoff?
Because the engines are burning large amounts of fuel and oxidizer every second (in some rockets as much as ten tons per second) and ejecting the products of this burning at high velocity to generate thrust.
What is Advantage of cryogenic engine in rockets?
More bounce per ounce of fuel..
How much fuel does a 707 use on take off?
This intercontinental long range plane burns 5 to 6 litres of fuel per second during take off until it reaches 3000ft then 3 to 4 liters per second until she reach cruising level at 35000ft where it burns 1 to 2 liters of fuel per second.This values are approximative.In her fuel taks she carries 80000liters of fuel.
Why do rockets need so much fuel for take off?
Rockets require a significant amount of fuel for takeoff primarily due to the need to overcome Earth's gravity and atmospheric resistance. The massive energy required to accelerate the rocket to escape velocity, which is around 17,500 miles per hour (28,000 kilometers per hour), necessitates a large amount of propellant. Additionally, the fuel must produce enough thrust to lift the entire vehicle, including its payload and the fuel itself, making efficient fuel usage crucial for successful launches.
How much fire power do you need to send a rocket to the moon?
It depends on the size, weight and shape of the rocket, but the amount of fuel used in NASA rockets is about 1000 tons of fuel per launch. The combined thrusting force required is around 25,000,000 N.
What is the speed of a rocket in meters per second?
Military rockets of the 1800s achieved velocities on the order of 100 meters per second. Robert Goddard achieved mach 1 (about 350 m/sec) with his rockets. To escape the gravity of our Earth, a rocket would need to achieve a velocity of about 11,000 m/sec. The X-15 rocket plane achieved a speed of over 110,000 meters per second.
How much Fuel airplane used per second?
Depends on the airplane type, the engine settings set by the pilot, etc. Small airplanes typically burn about 10 gallons per hour. Airliners can burn up to hundreds of pounds per second
How much does Bill Gates make per second?
300 per second
Which is faster 720 kilobytes per second or 300 megabytes per second?
300 megabytes per second is much faster.
How much money does Oprah make per second?
Ten dollars per second !!
At how much speed does a light travel per second?
It is about 186,000 miles per second
How much is 2500 kilometers per hour in meters per second?
i think that it is 694.44444 metres per second
