Which of the following operations does the small reaction control thrusters in Space Shuttle doesn’t serve?

Which of the following operations does the small reaction control thrusters in Space Shuttle doesn’t serve? Correct Answer Take-off

Same engines can be used for different purposes. An example for one such engine is the small reaction control thruster for the Space Shuttle which serves the main purpose of attitude control, but in addition to it plays a role in docking and small trajectory corrections as well. It is however not used for take-off as it is a low thrust, high specific impulse delivering device.

If Helal serves on football committee, which of the following must be true?
Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is
For a reaction, the extent of reaction equation is Ni = Nio + ϒVi is Where: Ni = Moles of species I present in the system after the reaction occurs Nio = Moles of species I present in the system when the reaction starts Vi = Stoichiometric coefficient for species i in the specified chemical reaction equation ϒ = Extent of reaction
