What else can I help you with?
Propellant propellent which is correct?
Propellant
One of the first propellant used was?
Gunpowderwas the first propellant used
Why are hollow cores used in some solid propellant engines?
To get an even burn through the full length of the propellant. Also, burning from the inside out keeps the propellant tube from overheating. A crack in the propellant would cause a burn to the tube wall and rupture before all the propellant is consumed.
What does Burn Time for a rocket mean?
The length of time from ignition of propellant to when all propellant has been consumed.
What causes rocket engines can obtain forward momentum with fuel additives?
Rocket engines achieve forward momentum by expelling exhaust gases at high speeds, based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. Fuel additives can enhance combustion efficiency, increase energy output, and improve the overall performance of the propellant, allowing for greater thrust. By optimizing the combustion process, these additives help generate more forceful exhaust, leading to increased acceleration and improved rocket performance.
What are two types of rocket propellant?
Two common types of rocket propellant are liquid propellant and solid propellant. Liquid propellant consists of fuel and oxidizer stored separately and combined in the combustion chamber, allowing for controlled thrust and engine shutoff. Solid propellant, on the other hand, consists of a mixture of fuel and oxidizer that is preloaded into the rocket, providing a simpler design but less control over the burn once ignited. Each type has its advantages and applications in different rocket systems.
What is the propellant used in whipped cream?
The propellant used in whipped cream is nitrous oxide, also known as laughing gas.
What was the first propellant that was used?
Bob.
Why hair spray is heterogeneous?
Hair spray is heterogeneous because it is made up of multiple components that do not form a uniform mixture. It typically consists of a solvent, propellant, polymer, fragrance, and other additives which do not blend together completely. This results in a visibly distinct mixture with different components that can be separated.
Th mixture of explosive chemicals housed within a bullet is called what?
The mixture of explosive chemicals housed within a bullet is called the propellant. This propellant is ignited by the primer when the trigger is pulled, causing the bullet to be propelled out of the firearm.
What is whipped cream propellant?
Nitrous Oxide
What was the first propellent used?
Liquid Propellant!!
