Trevon designed a toy rocket and ignited the propellant to see how high the rocket would travel. The toy rocket traveled 5 meters into the air. What should Trevon do to determine whether the force from the propellant is enough to push the rocket 5 meters into the air in repeated trials? Test the rocket several times using an identical amount of the same type of propellant.

Test the rocket several times using different amounts of the same type of propellant.

Test the rocket several times using different amounts and different types of propellant.

Test the rocket several times using an identical amount of different types of propellant.

Test the rocket several times using an identical amount of the same type of propellant.

Explanation:

Propellant is a chemical substance which produces energy that is used to move the object in upward direction. The energy that is produced will be emitted in the form of pressurized gases that provides upward thrust. In this experiment, the rocket travels 5 meters in the air after the ignition of propellant, if the Trevon wants to know that the propellant has the ability to move the toy rocket 5 meters in the air so he has to use same amount of propellant for other trials.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
